Configuration requirements for Tru64 UNIX on HP AlphaServer hosts

You must configure the operating system before you can use Tru64 UNIX® on HP AlphaServer hosts with the SAN Volume Controller.

Before you configure the host operating system, the following tasks must be completed:

Your IBM® service representative must have installed the SAN Volume Controller.
You must have installed the appropriate host bus adapter (HBA) and driver on your host system.

After the prerequisite tasks are complete, use the following general steps to configure your Tru64 UNIX host system.

Zone the host system to the SAN Volume Controller on the fibre-channel SAN.
Configure and map VDisks to the host.
For Tru64 UNIX 5.1 and later versions, you can discover the disks by using the hwmgr scan scsi command.
The disks are discovered as IBM 2145 disks, and the number of discovered devices depends on the number of adapters and zoned paths to the SAN Volume Controller.
Optionally, check the status and number of attached disks by using the following commands:
- hwmgr view devices
- hwmgr show scsi
- hwmgr show components

The following example shows output from the hwmgr view devices command:

# hwmgr v d
