Cannot Always Delete Selected Volume on MSA
MSA volumes must be deleted in the reverse order of their creation. For example, if you have six
volumes, and you want to delete the second one you created, you must delete the volumes one at a
time, starting with the volume created sixth and continuing with the fifth, fourth, third, and then the
second. Attempting to delete other volumes will return a generic error code 4.
If the volume deleted is the last volume of the storage array (also known as the storage pool), the
storage array is also deleted.
Selective Storage Presentation must be enabled on MSA
Selective Storage Presentation (SSP) for the array must be enabled for provisioning to work.
Issues Specific to LSI Storage Systems
This section contains the following topics:
• Creating and Deleting Storage Pools , page 569
• Creating and Deleting Storage Volumes , page 569
Creating and Deleting Storage Pools
For LSI, a storage pool is the same as a volume group. Create at least one storage pool before
provisioning a volume. When you delete a storage pool on an LSI storage system, all the volumes
for the volume group are deleted, including the placeholder volume.
Creating and Deleting Storage Volumes
Keep in mind the following when you create a volume on an LSI storage system:
• Make sure you select a volume group that can accommodate the requested size for the new
volume.
• You can create volumes from existing free extent areas within a volume group.
• The volume capabilities, their cache read ahead multiplier and segment size are shown in
