HP ProLiant Storage Server SAN Connection and Management Application Notes (5697-6495, September 2007)

Expanding storage for Enterprise Virtual Arrays (single node environment)

The act of presenting a virtual disk makes it available for use by a host. You can present a virtual disk to

a host during or af ter virtual disk creation. The virtual disk must be completely created before the host

presentation can occur. If you choose host presentation during virtual disk creation, the man agem ent

agent cannot complete any other task until that virtual disk is created and presented. Therefore, HP

recomm ends that you wait until a virtual disk is created before presenting it to a host.

Toextendavir

tual disk (single-node environment):

1. Using an HP StorageWorks Storage Management Appliance (SMA), or Command View EVA hosted

on a server, create or extend the virtual disk presented to the storage server.

2. On the storage server, open Device Manager, right-click the EVA LUN, and scan for hardware

changes.

3. Open a command prompt and run DiskPart.exe.

4. List the current volumes of the system (List Volum es).

5. Select the

volume to be extended (select volume X)

6. Extend the volume (extend [size=n], where size is optional).

7. ExtendaLUNforEVAstoragearrays(clusteredenvironment).

To extend a

LUNonanEVAstoragearrayinacluster:

1. Review re

quirements and procedures from the storage array hardware provider for expanding

or extending storage.

2. Ensure that Microsoft Windows Server 2003 SP1 is installed.

3. Run Command View EVA on the storage server to increase the size of the presented EVA LUN.

4. Run Microsoft DiskPart.exe to add the additional space to the volume.
