HP StorageWorks 3000/5000 Enterprise Virtual Array connectivity for IBM AIX installation and reference guide (5697-7040, November 2007)

Creating and pre
senting virtual disks
Use the followi
ng procedure to create and present additional virtual disks to the host servers:
1. Create a virtual disk on the Enterprise Virtual Array using HP Command View EVA.
2. Set values for the following parameters:
• Virtual disk name
•Vraidlevel
•Size
• Present to host (the host you just created)
The following
two values must be set as indicated:
• OS Unit ID should be set to 0.
• Preferred path/mode should be set to No Preference.
3. Select a LUN n
umber if you chose a specific LUN on the Virtual Disk Properties pag e.
4. Restart the server or rescan the bus.
NOTE:
There is a field on the Virtual Disk properties page for OS Un it ID. Set the OS Unit ID to zero for IBM
AIX hosts.
Verifying virtual disks from the host
This section describes how to verify that operating system hosts can access the virtual disks created on the
Enterprise Virtual Array with HP Command View EVA. The host can re cognize Enterprise Virtual Array
devices either through a system restart or by rescanning the bus.
Scanning the bus
Use the following procedure to scan the bus and display information about the Enterprise Virtual Array
devices:
1. Execute the following command:
cfgmgr -v
The cfgmgr command rescans the bus for additional resources. The -v switch (verbose output)
requests a full output.
2. Execute the following command:
lshsv
The lshsv command lists all the Enterprise Virtual Array devices. The output sho uld look similar
to the following:
hdisk3 Available 37-08-00-4,0 HP HSV110 Enterprise Virtual Array CCL
hdisk5 Available 3A-08-00-4,0 HP HSV110 Enterprise Virtual Array CCL
hdisk6 Available 37-08-00-4,1 HP HSV110 Enterprise Virtual Array
NOTE:
You should see a disk with the LUN ID that was assigned to the virtual disk in the HP
Command View EVA. In the sample output above, the LUN ID is 1.
If you are unable to access the virtual disk, check the following:
