14 Chapter 3 Notes > 3.3 Fibre Channel Switch Notes 3.3 Fibre Channel Switch Notes Which Fibre Channel switches can be connected to the ETERNUS Disk storage system varies depending on the connection environment (server OS and ETERNUS Disk storage system model). Refer to the "Server Support Matrix for FC-SWITCH" before starting. When using a Fibre Channel switch (ETERNUS SN200 series, Brocade DCX series) between the server and ETERNUS Disk storage system, refer to the "ETERNUS Disk storage systems Server Connection Guide (Fibre Channel) Fibre Channel Switch Settings" for help in preparing and setting up the Fibre Channel switch. If AIX server is connected to a Fibre Channel switch, the Fibre Channel switch port link speed must be set. Set the link speed of the Fibre Channel switch ports according to the link speeds of the server-side Fibre Channel cards, as follows: Fibre Channel card (Maximum link speed) Paired devices Fibre Channel switch (Maximum link speed) 8Gbps 8Gbps 8Gbps fixed 4Gbps 4Gbps fixed 2Gbps 2Gbps fixed 4Gbps 8Gbps 4Gbps fixed 4Gbps 2Gbps 2Gbps fixed 2Gbps 8Gbps 2Gbps fixed 4Gbps 2Gbps Set the Fibre Channel switch port link speed to... If the devices being connected together both have automatically set link speeds, the resulting link speed may be less than optimal. The default link speed setting for Fibre Channel switch ports is "Automatic". The link speed setting for true IBM Fibre Channel cards is always "Automatic". The link speed setting of a true IBM Fibre Channel card cannot be changed to other than "Automatic", so the Fibre Channel switch port link speeds must be fixed to match the actual speed of the server-side Fibre Channel cards, as per the above table, so that the same link speed is always used. 3.4 LVM Notes Disable [Bad Block Relocation] for a LVM logical volume that was created on ETERNUS Disk storage systems' LUN. Also, [Bad Block Relocation] must be disabled for the logical volume in which file system logs are stored. 14

15 Chapter 3 Notes > 3.5 Server Startup and Power Supply Control Notes 3.5 Server Startup and Power Supply Control Notes Before turning the server on, check that the ETERNUS Disk storage systems and Fibre Channel switches are all "Ready". If the server is turned on and they are not "Ready", the server will not be able to recognize the ETERNUS Disk storage systems. Also, when the ETERNUS Disk storage system power supply is being controlled by a connected server, make sure that the ETERNUS Disk storage system does not shut down before the connected servers. Similarly, the Fibre Channel switches must also be turned off after the connected servers have been shut down. If turned off, data writes from the running server cannot be saved to the ETERNUS Disk storage systems, and already saved data may also be affected. 3.6 VERITAS Volume Manager (VxVM) Notes Refer to "8.4 Installing the FJspio Package" and install the FJspio package on the AIX system before installing VxVM. Install VERITAS Array Support Library after installing VxVM. Installing VxVM VxVM should be installed as specified in its accompanying documentation. To use VxVM, set the Fibre Channel card parameters that are specified in the VxVM documentation. When using VxVM 4.0 or VxVM 5.0 If the ETERNUS Disk storage systems are connected to a configuration that uses the VxVM, the VERITAS Array Support Library (ASL) will also need to be installed. Which version of VERITAS ASL is required will depend on the storage system and version of VxVM used. Download the VERITAS ASL version that matches your environment from the following Symantec web-site. Refer to the Symantec web-site for VERITAS ASL installation details. Storage system VxVM ASL download URL ETERNUS2000 VxVM 5.0 MP1 or later ETERNUS4000 ETERNUS8000 VxVM 4.0 MP3 or later VxVM 5.0 MP1 or later When using VxVM 5.1 ASL does not need to be installed VERITAS Cluster Server (VCS) Notes VERITAS Cluster Server should be installed according to the directions given in the documentation provided with VERITAS Cluster Server. 15

16 Chapter 3 Notes > 3.8 Multipath Notes 3.8 Multipath Notes Refer to the "Server Support Matrix" for details of the different combinations of Multipath configurations. 3.9 Virtual I/O Server (VIOS) Notes Perform the settings described in this document only for a VIOS. When setting the VIOS, the root privilege for the VIOS environment is required. Make sure to install ETERNUS Multipath Driver 2.0 on the VIOS. When installing software on a VIOS, the root privilege for the VIOS environment is required. Only a virtual SCSI adapter connection is supported. Assign hdisk to the virtual SCSI adapter. Configuring LVM on the VIOS is not supported. 16

17 Chapter 4 Checking the Server Information Check the World Wide Name (WWN). Execute the following command to display the WWN of fcs0. # lscfg -vl fcs0 The WWN is displayed in the [Network Address]. If multiple Fibre Channel cards are installed, change the parameter and reexecute the command. 17

18 Chapter 5 Installing and Setting up ETERNUSmgr If ETERNUSmgr is to be used, install it according to the directions given in the "ETERNUSmgr Install Guide". After the installation, set up ETERNUSmgr following the instructions in the "ETERNUSmgr User Guide". 18

19 Chapter 6 Setting up the ETERNUS Disk Storage Systems Set up the ETERNUS Disk storage systems using ETERNUSmgr. ETERNUS Disk storage systems' setup can be performed independently of server setup.
