7 About the EMC Disk Library Introduction to the EMC Disk Library The EMC Disk Library combines hardware controllers with a storage-system disk into an appliance that makes virtual tape libraries available on a Fibre Channel storage area network (SAN). These virtual tape libraries are direct, plug-and-play replacements for physical libraries. The basic logical components of a EMC Disk Library system are: Virtual libraries Virtual tape drives Virtual volumes SAN clients Physical libraries (optional) Hardware and software components The EMC DL210 Disk Library rack series (or field install kit) includes the following base hardware components: One Intel-based EMC Disk Library server, which contains the following: One flexible-use port that you can interchange for either host connections, expansion storage connection, or a physical library configuration: o One auto-negotiating target port 1, 3, and 5 for connection to the Fibre Channel (FC) storage area network (FC SAN), or Direct Connection (FC-AL) with the backup systems. For information on supported switches and backup systems, refer to the EMC Support Matrix. o One auto-negotiating FC 4 Gb/s or initiator port 5 for physical tape libraries or physical tape drives. EMC supports a maximum of four physical tape libraries or physical tape drives per Disk Library server. Six available direct connections to the enclosed EMC AX-series storage system. One auto-negotiating 10/100/1000 Mbps Ethernet NIC to increase performance with LAN-based communications. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. Depending on the DL210 system ordered and configured, up to six AX-series Storage Enclosures can be added to the base appliance hardware. Adding Storage Enclosures (Shelves) increases the total aggregate capacity in the DL210 appliance. CAUTION The EMC storage system is preconfigured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC DL4x00 Disk Library rack series includes the following base hardware components: One or more Intel-based EMC Disk Library servers that contains the following: Eight flexible-use ports that you can interchange for either host connections or a physical library configuration: o Four auto-negotiating target ports 1, 3, 7 and 11 for connection to the Fibre Channel (FC) storage area network (FC SAN) with the backup systems. EMC does not support a direct connection to backup systems. For information on supported switches, refer to the EMC Support Matrix. 1

8 EDL printed help o Four auto-negotiating FC 4 Gb/s or initiator ports 4, 5, 8 and 9 for physical tape libraries or physical tape drives. EMC supports a maximum of four physical tape libraries or physical tape drives per Disk Library server. Note: The DL4200 and DL4400 front-end, flexible-use ports support FC-loop mode (FC-AL) only and require a switch that support FC-loop mode. FC-loop mode allows a single port to take on multiple WWPNs to support the active-active with active engine failover feature, if it is enabled. The backup hosts will still use FC-fabric mode (FC-SW) connections to the switch. The FC-AL to FC-SW interconnections are handled by the switch. FC-AL connections are required whether or not active engine failover is enabled. For information about the DL4200 and DL4400 configurations, refer to EMC Disk Library configuration. For information about the active-active with active engine failover, refer to Using active-active with active engine failover. Four direct connections to the enclosed EMC CX3 series storage system. Four auto-negotiating 10/100/1000 Mbps Ethernet NIC to increase performance with LAN-based communications. EMC Disk Library functions that use the network will see an advantage when additional network ports are used. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. Depending on the model, one or more CX3 series storage systems with one or more shelves of SATA (serial advanced technology attachment) drives, you can add shelves of 15 SATA disk drives to the base hardware. Adding shelves increases the total aggregate capacity of the CX3 series storage system as well as the capacity in the DL4x00 storage systems. CAUTION: The EMC storage system is pre configured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC DL6x00 Disk Library rack includes the following base hardware components: Two to Four Intel-based EMC Disk Library servers each of which contains the following: Four auto-negotiating FC target ports 1, 3, 7 and 11 for connection to the Fibre Channel (FC) storage area network (FC SAN) with the backup systems. Four auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 4, 5, 8 and 9 (in the DL6300) and two auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 4 and 8 (in the DL6100) for physical tape libraries or physical tape drives. Four auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 0, 2, 6, and 10 (in the DL6300) and six auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 0, 2, 5, 6, 9, and 10 (in the DL6100) for connection to the storage element. Four auto-negotiating 10/100/1000 Mbps Ethernet NICs per engine to increase performance with LAN-based communications. Note: The DL6100 and DL6300 front-end, flexible-use ports support FC-loop mode (FC-AL) only and require a switch that support FC-loop mode. FC-loop mode allows a single port to take on multiple WWPNs to support the active-active with active engine failover feature, if it is enabled. The backup hosts will still use FC-fabric mode (FC-SW) connections to the switch. The FC-AL to FC-SW interconnections are handled by the switch. FC-AL connections are required whether or not active engine failover is enabled. 2

9 About the EMC Disk Library For information about the DL6100 and DL6300 configurations, refer to EMC Disk Library configuration. For information about the active-active with active engine failover, refer to Using active-active with active engine failover. EMC Disk Library functions that use the network will see an advantage when additional network ports are used. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. CAUTION The EMC DMX storage system is preconfigured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC Disk Library Console program. You will install and run the Console program on a customerprovided management workstation with Windows 2000 SP2 or higher, Windows XP or Windows Server 2003 installed. The management station must have a LAN port that is connected to the same network to which the EMC Disk Library is connected. The network connection can be 10BaseT, 100BaseT, or GigE. For information on device and backup software package, refer to the EMC Disk Library Release Notes. EMC Disk Library configuration The EMC Disk Library is available in six configurations, which include the DL210, DL4100 (1 x 1), DL4200 (2 x 1) and, DL4400 (2 x 2), DL6100 (2 x 1), and DL6300 (4 x 1). Note: In the DL4200, DL4400, DL6100, and DL6300 configurations, virtual tape libraries created on one Disk Library host do not have access to tapes on the other Disk Library host. All DL4200 configurations come with a minimum of one DAE3P-SATA 15-disk shelf. You can add more shelves to the EMC storage system to increase the storage capacity. All DL210 configurations come with a minimum of one AX150SC storage system. You can add more AX150SC storage systems to increase the storage capacity. The DL6100 model can be configured from 4 to 6 Storage Cabinets. The DL6300 model can be configured from 6 to 10 Storage Cabinets. Adding cabinets increases the total aggregate capacity of the DMX series storage system as well as the capacity in the DL6x00 storage systems. The older configurations, DL310, DL710, DL720, and DL740, are supported with the upgrade to the EMC Disk Library Console. EMC recommends that you keep a configuration sheet listing the items below. You can use this configuration sheet in case you need to re-configure the EMC Disk Library manually. EMC Disk Library Configuration Sheet 3

10 EDL printed help About the EMC Disk Library Console You administer the EMC Disk Library through the EMC Disk Library Console, which you must install on a system in your environment. The Console is a user interface (UI) tool that you use to configure the EMC Disk Library, add and configure clients, set properties, and manage the import/export of tapes. You can use the Console to manage more than one EMC Disk Library. Note: The Console icon for v3.x on the management workstation will display as EMC Disk Library Console 3.x. You can install v2.x and v3.x on the same management workstation Related Topics: To install and set up the EMC Disk Library Console, see Installing and Setting Up the Disk Library Console. For information on the Console s main menu, tree, and main window options, see Trees, Menu Options, and the Main Window. 4

11 Installing and Setting Up the Disk Library Console Installing the EMC Disk Library Console program The EMC Disk Library Console is a Windows-based application. The management system on which you will install and run the EMC Disk Library Console program must have a LAN port that is connected to the same network to which the EMC Disk Library is connected. This enables communication between the management station and the EMC Disk Library server. The Disk Library Console uses TCP port to communicate with the Disk Library server, and UDP port for remote copy. If you plan to have the Disk Library Console and the Disk Library server communicate through a firewall, you must open up both these ports. For information on operating systems supported by the Disk Library Console, refer to the EMC Disk Library Release Notes. Note: Only a power user or an administrator can install the Console. To install the EMC Disk Library Console 1. Insert the EMC Disk Library Management Console Software and Documentation CD into the CD- ROM. The CD automatically launches a menu window. Note: If the CD does not automatically launch a menu window, navigate to the CD-ROM drive in an Explorer window and select the setup.exe file. 2. Select Software. The Software window displays. 3. Follow the instructions on the Software window to install the Console. Required procedures for the EMC Disk Library Console setup The following procedures are required to set up the Disk Library Console: Setting up and configuring the Disk Library Initializing the Disk Library DL210 servers Adding a Disk Library server to the Console Logging in to the Disk Library server Viewing and managing the event log Changing the default password Using the Configuration wizard Saving and restoring Mirroring the virtual tape library database 5

12 EDL printed help Setting up and configuring the Disk Library An EMC service provider sets up and configures the Disk Library. You can configure additional virtual tape libraries using the Disk Library Console. Default SAN client The Everyone_FC SAN client is the default SAN client. All non-configured host systems use the Everyone_FC SAN client. Once you have configured a host system as a SAN client, that system no longer uses the Everyone_FC SAN client object. If you assign one or more virtual tape devices (libraries or drives) to the Everyone_FC SAN client, then all non-configured host systems on the FC SAN with the Disk Library server will be able to use these resources (provided that FC switch zoning allows these host systems to see the Disk Library server). You can assign the default library to the Everyone_FC client. This is useful when you initially configure the Disk Library server because it allows the pre-configured virtual tape library to be available to all of the FC systems permitted by your FC zoning. Initializing the Disk Library DL210 servers Before you add a Disk Library DL210 to the Disk Library Console, you must initialize and set up the IP address on the Disk Library DL210 server. Follow the steps below to initialize and set up the IP address using the initialization wizard: 1. Go to Tools and select Initialize Disk Library servers. 2. The EDL Initialization Wizard will appear. Select Begin. 3. The available EDLs window will appear with the serial numbers of the available DL210s on your network. Select the serial number of the DL210 that you want to configure and select Configure. The IP Configuration window will appear. Enter the IP address and net mask for the DL210 and click Next. Note: Use a distinct IP address to initialize the Disk Library DL210 to avoid an IP address conflict. 4. The Gateway window will appear. You can enter an optional gateway and click Next. 5. A Finish window will appear with the configuration summary. Verify the details that appear in the window. Click Finish to complete the configuration. Once you initialize the DL210 system, it will disappear from the Available EDLs window. 6. To see the DL210 system in the Console, follow the steps in Adding a Disk Library server to the Console. Adding a Disk Library server to the Console The Disk Library Console communicates with each Disk Library via the Disk Library server. To add your Disk Library server to the Disk Library Console: 1. Open the Disk Library Console program. 2. In the EMC Disk Library Console window, right-click the Disk Libraries and select Discover. Note: Instead of performing a Discover, you can right-click your Disk Library server icon, and select Add. Enter your Disk Library server s IP address or IP name in the Disk Library Server text box. Enter dladmin in the User Name text box and password in the Password text box. For default username and password information, refer to Logging in to the Disk Library server. Click OK and skip to step 4. 6

13 Installing and Setting Up the Disk Library Console 3. In the Discover Disk Library Server dialog box, enter your subnet in the Subnet filter box. The Subnet filter will show the subnet information for the system on which you are running the Console program. The Disk Library server ships from the factory with the address Note: On a DL4200, DL4400, DL720, and DL740 server A ships with the default IP address , and server B ships with the default IP address On a DL6100 and DL6300, server A ships with the default IP address , server B ships with the default IP address , server C ships with the default IP address , and server D ships with the default IP address Note: model DL6100 only comes with server A and B. If you need to change the address, you can temporarily add an address in the subnet to the system running the Console program, for example, This allows the system to find the Disk Library server while it uses the default IP address. To change the IP address, see Accessing the Disk Library server through the Console. Click OK. 4. The Console program locates your Disk Library and adds an entry for the Disk Library under the Disk Library servers icon. Note: When you start the Disk Library server after an installation, it will not assign the address to its network interface card (NIC) if another system on the network is using the same IP address. To overcome this, you can either shut down the system or change its IP address. If the system does not have an IP address on the same sub-net as the Disk Library Appliance you would like to manage. Follow the procedures given in the link below, to add an IP address to the system on which you are running the Disk Library Console and access the Disk Library server through the Console. Accessing the Disk Library server through the Console After the Disk Library server is available on the network, follow the procedures in Setting up the network configuration in the Disk Library Console to set the network configuration in the Disk Library Console. Deleting a Disk Library server from the Console To delete your Disk Library server from the Disk Library Console, do the following: 1. Run the Disk Library Console program. 2. In the EMC Disk Library Console window, right-click the Disk Library server that you want to delete, and select Delete. The Console program removes this Disk Library server from the display. The Disk Library server will continue to function, and you can manage it from another Console program in your environment. Logging in to the Disk Library server 7

14 EDL printed help To log in to a Disk Library server: 1. Right-click your Disk Library server icon, and select Connect. 2. In the Disk Library User Login dialog box, you can log in with either of the two user names and passwords. Enter dladmin for Username and password for Password. Click OK. The Console Login dialog box opens, and displays server status messages, beginning with the message, Connecting to Disk Library Server. Logging in with this username and password provides you with privileges to access all the features of the Console. Enter dlmon for Username and monitor for Password. This login allows you to only monitor and create reports, but not edit them. Note: On a DL4200, DL4400, DL720, DL740, DL6100, and DL6300 the server you log in to will connect first, and then search the subsequent server(s) to connect. Viewing and managing the event log Once you have logged in to a server, you can view, filter, export, purge, or print the event log for that server as described in this section. The event log reports messages such as job completions, tape creations, user management, and hardware notifications. Viewing the event log Exporting the event log Purging the event log Printing the event log Changing the default password Once you have configured the Disk Library Console, you should change the default configuration password as follows: 1. Right-click the Disk Library server icon and select Change Password. 2. Enter the default password, a new password, confirm the new password. 3. Click OK. 8 Note: For information on the default username and password, refer to Logging in to the Disk Library server. Using the Configuration wizard Creating a virtual tape library and virtual tapes, and associating these with physical libraries and SAN clients, requires a number of steps. To simplify the standard configuration process, the Disk Library Console provides a configuration wizard. To open the Configuration wizard: 1. From the Console, select your Disk Library and right-click Virtual Tape Library System and select the Configuration wizard. Alternatively, you can click the Configure button that appears in the main window of the Disk Library Console. The wizard lists an overview of the standard configuration steps.

Manually saving the Disk Library configuration 9

16 EDL printed help Manually restoring the Disk Library configuration Mirroring the virtual tape library database Mirroring the database protects your configuration if the disk storing the database is lost. With mirroring, each time the data is written to the virtual tape library database, the same data is simultaneously written to the mirrored copy. The disk maintains an exact copy of the database. In the event that the database is unusable, the virtual tape library seamlessly swaps to the mirrored copy. Note: The mirroring feature is already set up (factory default), if needed you can use the following procedure to enable the mirroring feature. Follow the steps below to set the mirroring feature: 1. Select the Disk Library server you want and expand it. 2. Expand Virtual Tape Library System. Right-click Database, and select Mirror > Add. The Create Virtual Tape Library Database Mirror window opens. 3. In the Create Virtual Tape Library Database Mirror window, click OK to create the virtual tape library database mirror.

18 EDL printed help Using active-active with active engine failover The Disk Library active-active with active engine failover feature improves the availability and recoverability of the system. This feature uses two Disk Library servers that have the ability to recover from a failure of one of the servers, or from a loss of connection to one of the servers. Note: The active-active with active engine failover feature is optional on DL720, DL740, DL4200, DL4000 and standard on DL6100, and DL6300 configurations. The term engine in active engine failover refers to either one of the two, or four servers in a DL720, DL740, DL4200, DL4400, DL6100, or DL6300 respectively. The two Disk Library servers in a DL720, DL740, DL4200, DL4400, and DL6100 are peers that monitor the health of each other at regular intervals. For example, if Disk Library server A fails, then Disk Library server B will, in addition to its own emulation services, restart the emulation services that were provided by server A by taking ownership of those virtual devices and making them available to the backup hosts. Related Topics: Failover_requirements Setting_up_failover Suspending, resuming or removing failover Fibre_Channel_failover Zoning an EMC Disk Library configuration enabled for active engine failover Zoning an EMC Disk Library configuration enabled for active engine failover in a multi-fabric environment Failover options Failover_information_tab In a DL6300, the four servers are divided into two groups where Server A and B are a pair, and the Server C and D are a pair. Just as mentioned above for the DL720/740, and DL4200/4400 models, Server B can restart emulation services that were provided by the Server A. However, Servers C and D are a different pair and cannot resume emulation services for either Server A or B. To enable active-active with active engine failover in the Disk Library Console, you must purchase the failover license (failover is standard on DL6x00 series). After a failover, the active-active with active engine failover feature allows the Disk Library to re-establish the availability of the emulated devices; however, external actions will always be required to continue or restart backup operations to the Disk Library. The nature and degree of this external intervention depends on the backup software application and the operating system. When a failover occurs, the backup and restore jobs in progress to the failed server will terminate or be suspended, and will deliver a failure notification to the backup operator. This is in contrast to similar functions available with EMC storage systems that are designed to deliver transparent application level failover without any loss of data written to the storage system. This limitation is due to the nature of the backup applications and tape operation. Refer to the EMC Disk Library Release Notes for additional information. 12

19 Adding Optional Software and Console features About the tape shredding feature The tape shredding feature prevents specialized programs from reading data from deleted or erased virtual tapes. The tape shredding feature uses the US Department of Defense (DoD) M algorithm to erase data on virtual tapes by overwriting disk data with multiple patterns of bits, which makes it difficult or impossible to recover the original data. To use the tape shredding feature, see Using the tape shredding feature. Using the internal backup software inside the Disk Library This optional, licensed feature allows use of the NetWorker Storage Node or the Veritas Netbackup Media Server component of backup software inside the Disk Library. Note: You can install only one of the two licenses on your Disk Library at a time. It yields a Disk Library that supports all of its current functions (notably, emulating tape devices on a FC SAN). In addition, the internal backup software will use the Disk Library server resources to write to virtual and physical tape devices. A special SAN client allows virtual tape devices to be made available to the embedded internal backup software. This is especially attractive for tape duplication operations -- since the internal backup software running in the Disk Library is in charge of creating the duplicate media, the NetWorker or Netbackup software will know of the existence and location of any duplicate media. This is not the case with current Disk Library-directed duplication operations The embedded internal backup software is best used in the following scenarios: Local cloning / duplication Virtual tape libraries can be shared by the production storage nodes, which generate backup save streams that are written to virtual devices in the Disk Library, and by the embedded internal backup software. When backups are complete, the embedded internal backup software can clone / duplicate these backup save sets to physical tape devices attached to the Disk Library. Remote cloning Cloning can also occur between internal backup software-enabled Disk Library systems, such that savesets on virtual or physical tape in the local Disk Library can be cloned / duplicated via IP to a remote Disk Libraries, and then written to either physical or virtual tape. See website for white papers on using the Networker Storage Node or the Veritas Netbackup Media Server inside the Disk Library. To start or stop the internal backup software, or to check its status, refer to topic Trees, menu options, and the main window. 13

20 EDL printed help Using compression Backup software products commonly use the following two compression methods: Client-side compression performed by backup client software running on a backup client. Device-side compression performed inside the tape drives. Related Topics are: Benefits_of_enabling_compression To_enable_or_disable_compression The_compression_icon The Disk Library uses device-side compression. Note: Although you can use both client-side compression and device-side compression, EMC recommends using one or the other. Using both methods will not increase your storage capacity, but will degrade the throughput of the Disk Library. The Disk Library system incorporates software compression with an LZO algorithm that runs on the Disk Library server. You can enable or disable compression for the entire Disk Library; that is, the Disk Library server compression option applies globally to all the virtual tape devices in the system. The Disk Library server compression option is disabled by default. Some backup software packages can enable or disable device-side compression. If the Disk Library compression option is disabled, then enabling or disabling the device-side compression on the backup software will have no effect. If the Disk Library server compression option is enabled, and you disable device-side compression on the backup software, then compression will be disabled only for the virtual tape devices you selected. For the DL6x00 series models, a Hardware Compression Feature is standard. This uses a hardware component within the EDL engine which will perform all compression tasks in-line. The hardware feature is used be default in lieu of software compression, however if the compression hardware should fail for any reason software compression will be used. The setting in the console for both Hardware and Software compression is the same and the system will intelligently choose hardware compression if so equipped. Note: When using Disk Library compression, all the data on a virtual tape may not fit on a physical tape counterpart when exported. This is because of better efficiency of the LZO compression method on a Disk Library compared to data compression methods on tape drives such as SDLT s DLZ, SAIT s ADLC, and LTO s SDLC. Note: Hardware Compression feature is not supported on the DL2x0, DL3x0, DL7x0, and DL4x00 series models. Forwarding SNMP traps The storage system generates and sends Simple Network Management Protocol (SNMP) traps to the Disk Library server. When an event occurs on a storage system, it generates an SNMP trap that contains an event code and text that describes the error. The storage system sends the SNMP trap to the Disk Library server. The Disk Library server translates the SNMP trap and logs the event in the event log. You can view 14

21 Adding Optional Software and Console features the event log in the Disk Library Console. You can also configure the Disk Library Console to forward SNMP traps to an SNMP server that you specify. In the case of the DL6100 and DL6300 models the Symmetrix based storage system in these appliances will also call home to EMC separately, to notify EMC of any proactive service measures required on the storage system and notify EMC of any storage subsystem errors. To configure the Disk Library Console to forward SNMP traps: 1. In the Disk Library Console, right-click your Disk Library server and select Properties. The Server Properties window opens. 2. In the Server Properties window, select SNMP Maintenance. 3. In the SysLocation field, type the location where the Disk Library server is located. 4. In the SysContact field, type the contact details of the person providing technical support for the Disk Library server. 5. Select the Trap Level, which specifies the type of message that will be sent. The following five levels of messages are available: None No messages will be sent. Critical Critical errors that stop the system from operating properly will be sent. Error Errors (failures such as a resource is not available or an operation has failed) and critical errors will be sent.

About error forwarding Error forwarding is a program that automatically contacts EMC when a problem occurs on your Disk Library. Only a qualified EMC representative can set up and access the error forwarding feature on each Disk Library. For error forwarding features on the DL2x0 series, see Enabling EDL alerts. Using the Attention Required tab If a fault occurs on a storage system that is part of your Disk Library, the Disk Library Console indicates the fault as follows: The Disk Library server icon is displayed with a red exclamation point. An Attention Required tab is displayed in the main window of the Disk Library Console. The following events may activate the Attention Required tab: 15

22 EDL printed help A fault occurs or the storage processor (SP) write cache is disabled. A Disk Library server hardware issue occurs; for example, power supply fails. A physical library goes offline. Export activities occur. The Attention Required tab disappears after you address and resolve the event. Some events may require manual clearing. Note: When you first power up the Disk Library, the write cache is disabled until the standby power supply (SPS) is fully charged. A write cache indication can last 1/2-hour or longer when you power up the Disk Library. To view the fault messages, in the Disk Library Console, 1. Click the icon for the Disk Library server indicating the fault 2.

Click Next. 6. The Reports wizard opens and displays the Create the Report window. 7. Click Finish to create the report. Note: The reports generated are available in both textual and graphical formats. You can export the textual reports to be saved as a text file. Using the standby server Note: The standby server applies only to the DL710, DL4100, and DL210 configurations. It is not applicable to the DL720, DL740, DL4200, DL4400, DL6100 and DL6300 configurations. If your Disk Library has the standby server option, an EMC service provider has already mounted the second Disk Library server in the rack and cabled it to the storage system. Only the primary server s power cords are connected. The power cords for the standby server should not be plugged in. 18

25 Adding Optional Software and Console features CAUTION: Never power up both servers simultaneously! Doing so will corrupt the Disk Library software. To use the standby server Before using the standby server, you must: 1. Consult with your EMC service provider to verify that the primary Disk Library server has developed a hardware problem. 2. If possible, halt the primary server using the Disk Library Console. If you cannot halt the primary server, shut the primary server off. 3. Unplug the power cords from the primary server. 4. Plug in the standby server s power cords and turn the standby server on. 5. Since you can cable the primary server in different ways, the procedure for bringing the standby server completely online differs. Depending on the availability of switch ports, do one of the following: Cable the corresponding ports of the primary and standby servers to the same switch (or switches). When the standby server ports come online, each assumes the WWPN of the same numbered port in the primary server. With WWPN zoning in the switch, the transition is automatic. If the switch does not have enough free ports to accommodate cables from the standby server and the primary server, you must move each front-end target port cable from the primary to the standby server. Be sure to move the cable to the corresponding port on the standby server. For HP-UX and AIX, the transition is not automatic. Move each front-end target port cable from the primary to the standby server. Be sure to move the cable to the corresponding port on the standby server. Configuring Network Time Protocol (NTP) synchronization You can configure the Disk Library server to synchronize with clocks from Network Time Protocol (NTP) time servers. Note: In the DL4200, DL4400, DL6100, and DL6300 configurations, you cannot configure NTP on the two servers if they are configured for failover. Refer to ntp.isc.org for NTP and time server information. You can configure as many as five time servers. The Disk Library server polls the configured NTP time servers and uses the most accurate time server for clock synchronization. Note: The Disk Library server must have access to external networks to be able to reach a time server. To set up NTP on a Disk Library server: 1. Double-click the system time at the bottom right corner of the Console to open the Date and Time Properties window. 2. In the Date and Time Properties window, click the NTP tab. You can add, edit, re-order, and delete servers as follows: Click Add to add a time server to the server list. In the pop-up window, enter the time server name or IP address and click OK to add the time server. Note: The time server appears in the server list. You can add up to five time servers. Click Edit to edit a selected time server name or IP address. Click Up and Down to re-order time servers in the list. Click Delete to delete a selected time server from the server list. 19

Console Version Indicates the installed Disk Library Console version number and build number. Patches Indicates software patches that are installed. Configuring multi-node Disk Library server groups The multi-node feature allows you to group up to eight Disk Library servers to simplify management. The multi-node group could include a combination of the older models that include the DL310, DL710, DL720, and DL740, or the newer models that include the DL210, DL4100, DL4200, DL4400, DL6100, and DL6300 Disk Libraries. A Disk Library server can be part of only one multi-node group. All the Disk Libraries that form the multi-node group can be managed with a single login from the Disk Library Console. Note: Multi-node server groups containing DL210s cannot contain members of the DL4000 or DL6000 family. Only server groups of DL210s can be created. Pre-existing usernames do not get propagated when a Disk Library.
