Creating and presenting virtual disks

Use the following 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)

• Set the OS Unit ID located on the Virtual Disk Properties page to a unique value for each

virtualdisk.TheOSUnitIDmustbeuniqueacrosstheentireSAN.Itisdisplayedbyviewing

the output of a SHOW DEVICE command. The following example shows how a virtual disk

with the OS Unit ID set to 50 is displayed:

Disk $1$DGA50

CAUTION:

The storage administrator needs to plan the OS Unit ID numbers in advance. Ensure that no

duplicates are entered as more virtual d isks are presented to OpenVMS hosts. A duplicate OS UNIT

ID number can corrupt data through LUN identity confusion. Also ensure that the OS Unit ID

number is a value between 1 and 32767. The host does not recognize a value set to zero.

3. Select a LUN number if you chose a speciﬁc LUN o n the Virtual Disk Properties page.

4. Restart the server or rescan the bus.

To rescan the bus, enter the following command:

$ MC SYSMAN IO AUTO

Verifying virtual disks from the host

This section d escribes 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.
