■ OS Unit ID should be set to 0
■ Preferred path/mode should be set to “No Preference”
3. If you chose a specific LUN on the Virtual Disk Properties page, you are
prompted to select a LUN number.
4. Restart the server or rescan the bus.
OS Unit ID
There is a field on the Virtual Disk properties page for OS Unit 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 IBM AIX hosts can access the virtual
disks created on the Enterprise Virtual Array with Command View EVA. The host
can recognize devices either through a system restart or by rescanning the bus.
Scanning the Bus
Use the following procedure for the host to recognize virtual disks presented after
the initial program load (IPL).
1. Execute the command:
cfgmgr -v
The cfgmgr command rescans the bus for additional resources. The -v
switch (verbose output) requests a full output.
2. Execute the command:
lshsv
The lshsv command lists all of the Enterprise Virtual Array devices. The output
should 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
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:
■ Verify all cabling to the switch, Enterprise Virtual Array, and host.
