Page 7: Installing And Configuring Aix For The Xp Disk Array
1 Installing and configuring AIX for the XP disk array You and the HP service representative each play a role in installation. The HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from the HP service representative. -

Installing and configuring the disk array The HP service representative performs these tasks: Assembling hardware and installing software Loading the microcode updates Installing and formatting devices After these tasks are finished, you will use XP Remote Web Console, XP Command View Advanced Edition Software, or XP Array Manager to complete the remaining tasks listed below. -
Page 11: Host Group Mode (Option)
The following host group mode is available for AIX: Table 1 Host group mode (option) Host Group Mode Function Default Comments Veritas Storage Foundation for Oracle RAC, Previously MODE186 DBE+RAC Database Edition/Advanced Cluster for Real Application Clusters or if Inactive Do not apply this option Veritas Cluster Server 4.0 or later with I/O to Sun Cluster. -
Page 12: Setting The System Option Modes
Setting the system option modes The HP service representative sets the system option mode(s) based on the operating system and software configuration of the host. Notify your HP representative if you install storage agnostic software (such as backup or cluster software) that may require specific settings. Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using XP Remote Web Console (shown) or XP Command View Advanced Edition Software. -

Page 14: Fabric Zoning And Lun Security For Multiple Operating Systems
Figure 3 Multi-cluster environment Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems). How you configure LUN security and fabric zoning depends on the operating system mix and the SAN configuration. Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate zoning and LUN security as follows:... -
Page 15: Defining The Paths
Defining the paths Use XP Remote Web Console (shown) or XP Command View Advanced Edition Software to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.” In XP Remote Web Console and XP Command View, LUN mapping includes: Configuring ports Enabling LUN security on the ports... -
Page 16: Configuring Disk Array Devices
Use the lsdev command to display system device data and verify that the system recognizes the newly installed devices. The devices are listed by device file name. All new devices should be listed as “Available.” If they are listed as “Define,” you must do more configuration before they can be used. Example #lsdev -Cc disk hdisk0 Available 10-60-00-5, 0 16 Bit SCSI Disk Drive... -

Parameter Default Value Required Value Queue type None Simple Table 5 Device parameters-queue depth Parameter Recommended Value Queue depth per LU Queue depth per port (MAXTAGS) 1024 The recommended queue depth settings may not provide the best I/O performance for your system. You can adjust the queue depth setting to optimize the I/O performance of the disk array. - Page 18 Repeat these steps for each OPEN-x device on the disk array. TIP: The lsattr command also shows other useful information, such as LUN ID of the mapped LDEV, worldwide name of the disk array FC port, and N-Port ID. Another useful command for determining the slot position and port worldwide name of the FCA is the lscfg l hdiskx command.

Enter values for the following fields: SIZE of file system (in 512-byte blocks). Enter the lsvg command to display the number of free physical partitions and physical partition size. Calculate the maximum size of the file system as follows: (FREE PPs - 1) x (PP SIZE) x 2048 Mount Point: Enter mount point name. - Page 25 Mount the file system. Enter: mount mount_point_name Example # mount /vg01 Repeat step 1 for each new file system. Use the df command to verify the size of the file systems. The capacity is listed in 512-byte blocks. To list capacity in 1024-byte blocks, use the df k command.
- Page 26 Use the df command to verify that the file systems have successfully automounted after a reboot. Any file systems that were not automounted can be set to automount using the SMIT Change a Journaled File System screen. If you are using HACMP or HAGEO, do not set the file systems to automount. Example # df File system 512-blocks...

Page 47: Glossary
Glossary AL-PA Arbitrated loop physical address. array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P). - Page 48 OPEN-E). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. Logical unit number. A LUN results from mapping a SCSI logical unit number, port ID, and LDEV ID to a RAID group. The size of the LUN is determined by the emulation mode of the LDEV and the number of LDEVs associated with the LUN.
