7 Invisible Body Tag 1 Installing and Configuring the HBA and Driver This chapter describes the procedures for installing an EMC-approved QLogic host bus adapter (HBA) into a Sun Solaris host environment and configuring the host for connection to an EMC storage array over Fibre Channel. This chapter contains the following sections: Planning Zoning and Connections in a Fabric Environment Installing the HBA Installing the HBA Driver Configuring Host Files Partitioning and Labeling Devices Updating the HBA Fcode Symmetrix/Fabric Case Study Installing and Configuring the HBA and Driver 1-1

8 1 Installing and Configuring the HBA and Driver Planning Zoning and Connections in a Fabric Environment Before setting up the hardware in a fabric configuration with an EMC storage array, you should plan for the connectivity and fan-in/fan-out topologies, including zoning and Access Logix (CLARiiON) or Volume Logix (Symmetrix) configuration. For more information, refer to these documents: Switch manufacturer s user documentation (Symmetrix) Volume Logix Product Guide, EMC P/N Connectrix 2 Gb/s Enterprise Storage Network System Planning Guide, EMC P/N Refer to Symmetrix/Fabric Case Study on page 1-25 for a Symmetrix planning example. 1-2 EMC Fibre Channel with QLogic HBAs in Solaris Hosts

9 Installing and Configuring the HBA and Driver 1 Installing the HBA Follow the instructions included with your adapter, including installation of all required Solaris system patches. The adapter installs into a single slot, and has no user-configurable jumpers or switches. Indentifying QLogic HBAs Each QLogic HBA is identified in the Solaris host by the driver instance number. An administrator can determine the mapping between the physical card and the driver instance X as follows: 1. Reboot the host with the -r option. 2. View the /var/adm/messages file and search for information similar to the following: Jun 16 15:48:02 losao067 qla2200: QLogic qla2200 Fibre Channel Driver v4.05 Instance: 3 Jun 16 15:48:04 losao067 qla2200: qla2200-hba3-adapter-node-name="200000e08b0035ec"; Jun 16 15:48:04 losao067 qla2200: qla2200-hba3-adapter-port-name="210000e08b0035ec"; Installing the HBA 1-3

10 1 Installing and Configuring the HBA and Driver Installing the HBA Driver Using the QLogic adapter with the Solaris operating system requires HBA I/O driver software. The driver functions at a layer below the Solaris SCSI driver to present Fibre Channel devices to the operating system as if they were standard SCSI devices. If an earlier version of the HBA port driver package is already installed on the server, you must remove it before installing the new version. The naming convention for the drivers, associated files, and messages is QLA; however, the Solaris SPARC driver supports standard QLogic PCI boards (QLAxxxx) and cpci boards (QCPxxxx). To install the driver: 1. Be sure you have the latest qualified driver software. If necessary, you can download the driver from the QLogic Web site. Refer to release notes provided with the driver for information that might be unique to new driver revisions. 2. The next step depends on the type of installation: Type of Installation Go to: New Installing a New Driver on page 1-4 Upgrade Installing a Driver Upgrade on page 1-7 Installing a New Driver Use the following procedure to load the driver from the QLogic CD-ROM, and perform a first-time install. 1. Log on to the system as a superuser. 2. From the root of the system, create a driver directory: mkdir qlogic_driver 3. Insert the QLogic CD-ROM. 1-4 EMC Fibre Channel with QLogic HBAs in Solaris Hosts

11 Installing and Configuring the HBA and Driver 1 4.

Installing the HBA Driver 1-9

16 1 Installing and Configuring the HBA and Driver 13. The pkgadd program notifies you when the driver installation is complete. 14. If you do not have any boot devices configured on the EMC storage array, go to step 15. If you have one or more boot devices configured on the EMC storage array, you must copy the binding information from the old qla2x00.conf file (that you backed up in step 2) to the new qla2x00.conf file, or you will not be able to access the GUI. Use any text editor to copy the binding information from one file to the other. 15. Edit any necessary files as described under Configuring Host Files on page Reboot the host with the -r (reconfigure) option: reboot -- -r Driver-Related Issues Note these issues (and resolutions) related to installing a QLogic adapter: Scenario 1 The server already contains a QLogic HBA that is controlled by the Sun ifp or qlc driver If the additional adapter is installed before installing the QLogic driver, both adapters will be initially controlled by the Sun ifp or qlc driver. When the QLogic driver is installed it will indicate that it is installed but has failed to attach. This is okay, since the driver will attach itself to the second adapter after a reboot with the reconfigure option (reboot -- -r). By default, each QLA2200 and QCP2202 adapter distributed by Sun has a PCI subsystem device ID of 0x2200. You must remove and reinstall the qlc driver using this default subsystem device ID if you do not want the qlc driver to attach to the adapters distributed by QLogic without the presence of the QLogic drivers. To do this, issue the following commands: rem_drv qlc add_drv -c fibre-channel -i "pci1077,2200" -n qlc 1-10 EMC Fibre Channel with QLogic HBAs in Solaris Hosts

17 Installing and Configuring the HBA and Driver 1 Scenario 2 The server has a QLA2200 built into the motherboard The Sun Fire 280R is an example of a server with a built-in adapter. If the built-in QLA2200 has PCI subsystem device IDs of 0x2200 (pci1077,2200), the following steps are recommended: a. Install the EMC-qualified QLA2200 driver into the host system. b. Halt the host system and power it off. c. Install the QLA2200 adapter(s). d. Boot the system with the reconfigure option (boot -rv). Installing the HBA Driver 1-11

18 1 Installing and Configuring the HBA and Driver Configuring Host Files Once the EMC storage array has devices assigned with device addresses and the directors have been switched on line, the host can see all the target storage array devices assigned to that host interface. Devices are presented to the host in the same manner as devices accessed through a standard SCSI interface. To insure smooth integration and maximum performance from the host and EMC storage array, you must edit these files: QLogic driver configuration file Refer to Setting QLogic Driver Configuration Variables on page Host sd driver configuration file sd.conf Refer to Editing sd.conf to Add LUNs on page System specification file /etc/system Refer to Editing /etc/system on page After editing the files, type reboot -- -r and press ENTER to reboot the host with the -r (reconfigure) option, which rebuilds the kernel and implements the changes. QLogic Persistent Binding Implementation This section applies only to fabric configurations. QLogic persistent binding is implemented through the file /kernel/drv/sd.conf and either the GUI or /kernel/drv/qla2200.conf (or qla2300.conf). The matching between the storage array port, the target ID, and the driver happens inside qla2200.conf (or qla2300.conf). Each mapping is considered a single property. The format for each binding entry must be followed by the HBA information. Each entry works as the mapping between the WWN of the HBA and the driver instance. Example: hba0-scsi-target-id-0-fibre-channel-node-name=" bbff7a9c"; hba0-scsi-target-id-0-fibre-channel-port-name=" bbff7a9c"; In this example: The X in hbax-scsi is the driver instance number of the HBA. This instance number corresponds to the instance entry inside the /etc/path_to_inst EMC Fibre Channel with QLogic HBAs in Solaris Hosts

19 Installing and Configuring the HBA and Driver 1 The Y in SCSI-target-id-Y is the device address, as in the following address: /dev/rdsk/c3tyd0s0. The fibre-channel-node-name and fibre-channel-port-name are the target WWNN and WWPN of the EMC storage array. On a Symmetrix console, this information can be found using the e2 command. The output is similar to the following example for Fibre Channel director port 13B: WWN WWN HI LOW / BBFF7A9C / BBFF7A9C The WWNN and WWPN of Symmetrix Fibre Channel port 13B are both BBFF7A9C. Multiple entries for the binding must be matched with the multiple distinct target ID, as in the following example: hba4-scsi-target-id-0-fibre-channel-node-name=" bbff7a80"; hba4-scsi-target-id-0-fibre-channel-port-name=" bbff7a80"; hba4-scsi-target-id-2-fibre-channel-node-name=" bbff7a9c"; hba4-scsi-target-id-2-fibre-channel-port-name=" bbff7a9c";! CAUTION If the HBA WWPN in the NVRAM is different from what specified inside qla2200.conf/qla2300.conf, the adapter will be assigned the NVRAM WWPN. The matching between the target ID and the LUNs happens inside /kernel/drv/sd.conf. Each of the entries represent a LUN Z, as in the device address: /dev/rdsk/c0t0dzs0. Because of the class="scsi" entries, the sd target driver will probe multiple adapters, even multiple adapters across multiple drivers (for example: isp, glm, fas). Configuring Host Files 1-13

20 1 Installing and Configuring the HBA and Driver Example: # # Copyright (c) 1992, by Sun Microsystems, Inc. # #ident "@(#)sd.conf /05/03 SMI" _ name="sd" class="scsi" target=0 lun=0; name="sd" class="scsi" target=0 lun=1; name="sd" class="scsi" target=0 lun=2; name="sd" class="scsi" target=0 lun=3; name="sd" class="scsi" target=0 lun=4; name="sd" class="scsi" target=0 lun=5; name="sd" class="scsi" target=0 lun=6; name="sd" class="scsi" target=0 lun=7; name="sd" class="scsi" target=0 lun=8; name="sd" class="scsi" target=0 lun=9; QLogic implements auto-binding at all times. To prevent the undesired effects of auto-binding, all targets must be bound to target IDs. Any target you do not want bound must be designated with a target ID that is not defined in sd.conf. Setting QLogic Driver Configuration Variables To edit the QLogic driver configuration variables, follow these steps: If this is a new installation of the GUI, you must reboot the host before you can open the GUI. 1. Open the QLogic SANblade Control FX Application (SANblade GUI): cd /opt/qlgic_corporation/sanblade_control_fx./scfx 2. Click the host name s pin located at the upper left of the SANblade GUI. 3. Click an adapter for which you want to set the variables; for example, Adapter 2200 (Instance #0). 4. At the Tab dialog, click HBA Options EMC Fibre Channel with QLogic HBAs in Solaris Hosts

Select Advanced Firmware Parameters, and set the variables according to the following table: Variable Required Setting if No PowerPath or Veritas DMP Required Setting if PowerPath or Veritas DMP Enable Adapter Hard Loop ID Enable Enable Hard Loop ID Enable LIP Full Login Enable Enable Login Retry Count FC-AL: 5 FC-SW: 10 FC-AL: 5 FC-SW: 10 Enable Class 2 Service Disable Disable Interrupt Delay Timer 0 0 Enable ACK0 Disable Disable Enable Read Transfer Ready Disable Disable Operation Mode No Multiple Responses No Multiple Responses When finished, click Save. 6. At the Tab dialog, click Target Setting. In the Target ID field, the user can bind the target device by any ID in the range When finished, click Save. Once the user saves the configuration, all targets that have the Bind column checked will be persistently bound in the configuration file /kernel/drv/qla2x00.conf. Example: hba0-scsi-target-id-1-fibre-channel-node-name=" c3a0d752"; hba0-scsi-target-id-1-fibre-channel-port-name=" c3a0d752"; 7. Repeat step 3 through 6 to set the variables of any other QLogic adapters. 8. On the SANblade Control FX main window File menu, select Exit to exit the QLogic SANblade Control FX GUI. Changes to the variables will not take effect until the host is rebooted EMC Fibre Channel with QLogic HBAs in Solaris Hosts

23 Installing and Configuring the HBA and Driver 1 Descriptions of the Driver Configuration Variables Here are the descriptions: Connection Options Defines the type of connection (loop or point-to-point) or connection preference. Port Down Retry Count Specifies the number of times the software retries a command to a port returning port down status. Frame Size Specifies the maximum frame length supported by the QLA2xxx adapter. Execution Throttle Specifies the maximum number of commands executing on any one port. When a port s execution throttle is reached, no new commands are executed until the current command finishes executing. Enable Fibre Channel Tape Support Enables/disables Fibre Channel tape support. Enable Fibre Channel Confirm Enables/disables the Fibre Channel Confirm option, which is used only in configurations that require Fibre Channel tape support. Data Rate determines the QLA23xx board data rate. Settings include: 1 GB/sec The QLA23xx board runs at 1 Gb/s. 2 GB/sec The QLA23xx board runs at 2 Gb/s. Auto-negotiate An attempt is made to determine what rate your system can accommodate. The rate is set based on the interrogation. Persistent Targets Plus New Reports to the OS the discovery of persistent bound and non-bound devices. If this field is checked and the configuration saved, it sets the persistent-binding-configuration parameter in the configuration file to 0. Persistent Targets Only Reports to the OS the discovery of persistent bound targets only. If this field is checked and the configuration saved, it sets the persistent-binding-configuration parameter in the configuration file to 1. This field is mutually exclusive with Persistent Targets Plus New (previous entry), meaning that only one of these can be selected at a time. Configuring Host Files 1-17

24 1 Installing and Configuring the HBA and Driver Persistent Bind HBA If set, the current HBA is bound in the configuration file. The application binds the HBA s OS instance number with the World Wide Node Name and World Wide Port Name of the HBA. Fast Error Reporting Enables/disables the ability of the OS to handle the rate at which errors are returned. Setting the field sets the value of the fast-error-reporting parameter in the configuration file to 1 (enabled), and vice versa. Link Down Error Disables the driver error reporting during link down conditions. Loop Down Timeout Specifies the amount of time the driver will wait for a Fibre Channel loop to come up before reporting the failure. Setting this field to small values may report transient errors that should be ignored. Enable Target Reset Enables the drivers to issue a Target Reset command to all devices on the loop when a SCSI Bus Reset command is issued. Enable Fast Command Posting Decreases command execution time by minimizing the number of interrupts. Enable 4GB addressing Should be enabled if the system has more than 4 GB of memory available. Maximum LUNs per Target Specifies the number of LUNs per target. Enable Adapter Hard Loop ID Forces the adapter to attempt to use the ID specified in the Hard Loop ID setting. Enable LIP full login Instructs the ISP chip to re-login to all ports after any loop initialization process (LIP). Enable Class 2 service Enables Class 2 service parameters to be provided during all automatic logins (loop ports). Enable ACK0 Determines the type of ACK used: Enabled = use sequence ACK. Disabled = use frame ACK. The Enable Class 2 Service setting must be enabled to use the Enable ACK0 setting. Enable Read Transfer Ready Is reserved. The default is Disabled EMC Fibre Channel with QLogic HBAs in Solaris Hosts

25 Installing and Configuring the HBA and Driver 1 Hard Loop ID Is an ID the adapter will attempt to use if Enable Adapter Hard Loop ID is enabled. Login Retry Count Specifies the number of times the software tries to log in to a device. Interrupt Delay Timer Specifies the time (in 100-microsecond increments) used by a timer to set the wait time between accessing (DMA) a set of handles and generating an interrupt. Operation Mode Specifies the reduced interrupt operation (RIO) modes, if supported by the software driver. RIO modes allow posting multiple command completions in a single interrupt. Editing sd.conf to Add LUNs Solaris maintains a configuration file named /kernel/drv/sd.conf, which lists all disks (LUNs) that a user may want to access. This file contains entries for LUN 0 only. As a result, you must edit the file to add entries for any LUNs with numbers greater than 0 that you will bind in the storage systems connected to the server. Before editing the current /kernel/drv/sd.conf file, make a copy of it just in case the file is lost or errors are made. When editing the file, follow these precautions: Do not delete any original data from this file; the Solaris operating system might not boot properly. Do not insert hidden format characters. The file is very sensitive to hidden format characters, and a misplaced tab or other formatting character can make all subsequent entries unreadable. Enter all LUN numbers as decimal numbers. Changes to sd.conf will not take effect until the host is rebooted. Devices accessed via Fibre Channel using the QLogic driver are addressed behind a single target ID with up to 256 LUNs. (This differs from existing SCSI device addressing, which might have multiple targets and LUNs.) In the standard EMC storage array device definition file, target 0 should have 256 LUNs, and all other targets (1 through 125) have a LUN 0 only. Edit sd.conf to list all targets and all LUNs that might be addressed. The Target ID needed to address a device is determined by the Fibre Channel Arbitrated Loop Physical Address (AL_PA). A Loop_ID of Configuring Host Files 1-19

26 1 Installing and Configuring the HBA and Driver 00 (AL_PA of EF) will have LUNs behind Target ID 0, Loop_ID 01 has LUNs on target ID 1, and so on. Since each Fibre Channel port can have only one loop ID (or AL_PA), all devices accessed through a port will have the same target ID. If you need to access existing devices that previously had multiple target IDs, be aware of changes required for raw device addressing. Your actual target/lun assignment will vary depending on unique system configuration requirements. Be sure that existing and new configurations are well documented before upgrading to Fibre Channel directors. Make sure that only the target=x lun=0 line is specified for any target ID that does not need LUN support. This decreases the time needed to reboot the system. Sample sd.conf file Here is an example of sd.conf: name= sd class= scsi target=0 lun=0; name= sd class= scsi target=0 lun=1;.. name= sd class= scsi target=0 lun=255; name= sd class= scsi target=1 lun=0; name= sd class= scsi target=2 lun=0;.. name= sd class= scsi target=125 lun=0; Device definition files are available on EMC s FTP server, ftp.emc.com, in /pub/elab/solaris. The file sd.conf.fibre is a device definition file for Fibre Channel devices. Change the file name to sd.conf and copy it to the /kernel/drv directory. Editing /etc/system Operation in a Solaris environment requires that some parameters in the file /etc/system first be modified, as described in this section.

27 Installing and Configuring the HBA and Driver 1 The modification to the parameter sd_max_throttle is required specifically for Fibre Channel. Other settings apply to both standard SCSI and Fibre Channel. 1. Type set sd:sd_max_throttle=20 and press ENTER. 2. Type set scsi_options = 0x7F8 and press ENTER. The bit meaning for scsi_options is as follows: Bit Mask Meaning 3 0x8 Disconnect enable 4 0x10 Link enable 5 0x20 Sync xfer enable 6 0x40 Parity support enable 7 0x80 Tag commands enable 8 0x100 Fast SCSI enable 9 0x200 Wide SCSI enable 10 0x400 Ultra SCSI enable Since /etc/system can also affect other disks in the system, consider the effects of implementing the scsi_options=0x7f8 mask on the other disks. If it is not set, EMC storage array operations will not benefit from these options. 3. The next step depends on whether the host will run PowerPath: If yes, add this line: set sd:sd_io_time = 0x3C If no, add this line: set sd:sd_io_time = 0x78 This setting prevents the host from issuing warning messages when non-disruptive operations are performed on the EMC storage array.

HBA-based zoning includes only one HBA port and single/multiple target ports per zone. For further information on zoning, refer to the Connectrix Enterprise Network System Planning Guide. Volume Logix requires an available Symmetrix device as the gatekeeper for administration on a particular host. Any of the hosts in the example may contain a gatekeeper, which must be assigned in /kernel/drv/sd.conf. Any of the devices defined in the gatekeeper must be mapped to the certain LUN number associated with the Symmetrix port; for example, device 0x80 LUN 0 of FA 3A. For further information on Volume Logix, refer to the Volume Logix Product Guide. The switch zoning must coincide with Volume Logix mapping to allow probing any Symmetrix devices. Such planning as that shown in the table can help present a complete picture before setting up the persistent binding EMC Fibre Channel with QLogic HBAs in Solaris Hosts

37 Invisible Body Tag 2 Configuring a Boot Device on the EMC Storage Array EMC supports booting Solaris from the storage array through an EMC-qualified QLogic Fibre Channel HBA. (Refer to the EMC Support Matrix for specific HBAs and drivers.) This chapter contains the following sections: Configuring a Symmetrix Boot Device Configuring a CLARiiON Boot Device Configuring a Boot Device on the EMC Storage Array 2-1

38 2 Configuring a Boot Device on the EMC Storage Array Configuring a Symmetrix Boot Device Partitioning the Boot Device 1. Use the format command to verify that the sizes of the partitions on the Symmetrix device chosen for the Solaris installation are large enough to copy the current OS partitions. Examine the partitions of the host source drive where the current OS resides: a. At the %> prompt, type format and press ENTER. b. When prompted choose disk 0, press ENTER. c. At the fomat> prompt, type partition and press ENTER. d. At the partition> prompt, type print and press ENTER. Sample output: Part Tag root swap backup unassigned unassigned unassigned usr home Flag wm wm um wm wm wm wm wm Cylinders Size MB MB 2.12GB MB 1.28GB 2. Select the Symmetrix device on which to install the Solaris operating system as follows: a. At the partition prompt, type quit and press ENTER to return to the format menu. b. At the format prompt, type disk and press ENTER. c. Information similar to the following appears: AVAILABLE SELECTIONS c0t0d0 <SUN4,2G cyl 3880 alt 2 hd 16 sec 135> /pci@1f,4000/scsi@3/sd@0,0 2. c3t0d0 <EMC-SYMMETRIX-5265 cyl 4088 alt 2 hd 15 sec 64> /pci@1f,4000/qlgc,qla@4/sd@0,0... specify disk (enter its number): Type 1 and press ENTER. 2-2 Symmetrix Fibre Channel with QLogic HBAs in Solaris Hosts

39 Configuring a Boot Device on the EMC Storage Array 2 Important: Make sure your Symmetrix device path has the form /pci/qlgc,qla. If the path has the form /pci/scsi, you must down load Fcode again and then reboot the system with the command reboot -- -rv. 3. Repartition the Symmetrix device (if necessary) to model the partition information from the host source drive in order to match the drive configuration: a. At the format prompt, type partition and press ENTER. a. At the partition prompt, type modify and press ENTER. b. After the partition in the Symmetrix device has been created, type modify and press ENTER at the format prompt. Creating Filesystems Create filesystems on the required partitions in the designated Symmetrix Boot device. Below is an example in which the OS is being copied to a Symmetrix device of Target 0 LUN 0 on controller 2: newfs /dev/rdsk/c3t0d0s0 newfs /dev/rdsk/c3t0d0s6 newfs /dev/rdsk/c3t0d0s7 To use a different Symmetrix Device, change t0 to t<symmetrix Device target number>. To use a different controller, change c3 to c<controller number>. You must create both the root partition (slice 0) and the /usr partition (slice 6). You should also create other partitions (/export/home, /var, /opt) to mirror the current layout. Use the newfs command to create the filesystems. Installing a Bootblk Install a bootblk (the information required by the host to boot the operating system) on the root partition of the Symmetrix boot device. 1. Use the uname -a command to determine the architecture of the workstation. This determines the directory in /usr/platform where the bootblk will be found. The example below gives sun4u as the architecture, and subdirectory for /usr/platform. Example: At the %> prompt, type uname -a and press ENTER to display a line similar to the following: SunOS patriot 5.8 Generic_ sun4u Sparc SUNW,Ultra-60 Configuring a Symmetrix Boot Device 2-3

40 2 Configuring a Boot Device on the EMC Storage Array 2. At the %> prompt, enter the following to install a bootblk onto the Symmetrix boot device: /usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/ c<controller number>t<symmetrix device target number>d0s0 For example, entering the following installs a bootblk onto a boot device of Target 0 LUN 0 on controller 1: /usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0 Note the information about the boot device s path. This information will be useful later, in the procedure for modifying OpenBoot. In the example above, your boot device s path is /pci@1f,4000/qlgc,qla@4/sd@0,0. Copying Required Files Use ufsdump and ufsrestore to copy the required files and directories from the host source drive to the Symmetrix boot device. 1. At the %> prompt, type mount /dev/dsk/c3t0d0s0 /mnt and press ENTER to mounts the root directory of the Symmetrix device to /mnt. 2. Use the ufsdump command to create the required directory structure on the new Symmetrix device and copy the files. Below is an example where the current operating system is located on /dev/dsk/c0t0d0. Example: At the %> prompt, type the following and press ENTER: ufsdump 0f - /dev/dsk/c0t0d0s0 ( cd /mnt; ufsrestore rf - ) When the above command completes, the Symmetrix device (c1t0d0s0) will have the complete image of the root partition. 3. In the /mnt/etc directory update the vfstab file to indicate the Symmetrix boot device address to be mounted during boot. Modify all partitions that will be located on the Symmetrix boot device. a. At the %> prompt, type cd /mnt/etc and press ENTER. b. At the %> prompt, type vi vfstab and press ENTER. 2-4 Symmetrix Fibre Channel with QLogic HBAs in Solaris Hosts
