5. After the virtual disk and volumes are created successfully, the volumes can be discovered as
back-end LUs from VSM GUI as shown below.
6. Create a storage pool using the MSA back-end LUs. Use this pool to create SVSP virtual disks
based on your requirements.
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 MSA and add it to the
same 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 any array-based features such as local replication 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.
Using non-HP branded arrays
The general process is:
1. Create a LUN using the array's management software with properties similar to those of an EVA
LUN, for example, failover with autofailback.
2. Present the LUN to at least one and not more than two quads per DPM and both VSM servers of
the SVSP domain, consistent with the array-to-DPM zoning.
