HP StorageWorks SAN Virtualization Services Platform administrator guide (5697-8056, March 2009)

• Array to VSM servers
• If adding the array also involves using a new DPM quad, add the new DPM quad to the VSM
server zones and verify that the DPM ports are licensed.
• Using the management interface of the new array, create or define DPMs and VSMs as hosts, and
then present the back-end LUs to the DPMs and VSMs. Each pair of quads should have a unique
host definition.
• Refresh the VSM software using the VSM refresh button. Once the new back-end LU is visible, use
it and others to create stripe sets, then create pools. Use the pools to create front-end virtual disks.
• Refresh the VSM software using the VSM refresh button. Once the new back-end LU is visible, use
it and others to create stripe sets, then create pools. Use the pools to create front-end virtual disks.
Adding EVAs
When using HP Command View EVA to create back-end LUNs on the EVA that will be presented to
the SAN Virtualization Services Platform domain (both DPM and VSM servers), or when presenting
existing EVA virtual disks to the domain (for data import) the following presentation rules apply:
• Each DPM quad and each VSM server must be defined as hosts and include all ports.
• Create a small number of large LUNs rather than many smaller LUNs.
• Display the virtual disk to the DPM quad and VSM server using the same LUN number. The EVA
virtual disk must be presented to both the DPM and VSM servers.
• The LUN must use the appropriate preferred controller setting of “failover/auto failback” option,
and not “no preference.”
NOTE:
• Do not expand LUNs that are already configured in VSM. If a particular storage pool runs out of
free space and you want to expand it, create a new virtual disk on the EVA and add it to the pool.
• Do not change LUN numbers for LUNs that are already managed by VSM.
• Remove LUNs from VSM management only after releasing them from storage pools and stripe
sets.
• Do not use HP Business Copy EVA or HP Continuous Access EVA on any virtual disk presented
to the SVSP domain.
• Once a virtual disk is presented to the SVSP domain, do not change any characteristics of the
virtual disk.
Adding MSAs
The following process describes how to create back-end LUs on an MSA2000 and present them to
SVSP. For other MSAs, consult the MSA documentation.
