because the HiCommand Database was not refreshed. The management server does not support
provisioning for ports designated as Initiators on these storage systems.
The Software Is Unable to Map a Host to Volumes
in Different Host Storage Domains of the Same Port
on HDS 9900V
On HDS 9900V storage systems, if a host is already mapped to a volume and you try to map the
same host to a volume in another host storage domain, corresponding to the same port, it will fail.
However for HDS 9900, the host can be mapped to a volume in another host storage domain
corresponding to the same port.
A Default LUN Number Is Used Instead of a User-Specified One
When you create a LUN, the user-specified LUN is ignored. The LUN is created with the next
available default number.
Issues Specific to HP Storage Systems
• ”Size Reported as 0 on EVA Array Volumes of 1 GB or More (Correct Size is Reported After
Running Get All Details on EVA Array” on page 380
• ”Cannot Always Delete Selected Volume on MSA, MSA Allows Deletion of Only Topmost or
Last Volume” on page 380
Size Reported as 0 on EVA Array Volumes of 1 GB or
More (Correct Size is Reported After Running Get All
Details on EVA Array
If you create a volume of 1 GB or more on an EVA, the size reported is 0 until a Get All Details is
run on the EVA array. Smaller volume sizes do not exhibit this problem. This is a limitation in the
EVA array software, and AppIQ is working with HP to resolve this issue.
Cannot Always Delete Selected Volume on MSA, MSA Allows Deletion of
Only Topmost or Last Volume
You can delete only the last or topmost volume on each of the MSA array’s controllers (modeled as
pools). Attempting to delete other volumes will return a generic error code 4. This is a limitation in
the MSA array software and AppIQ is working with HP to resolve the issues.
Issues Specific to Engenio Storage Systems
This section describes the following for Engenio:
• ”Creating and Deleting Storage Pools” on page 380
• ”Creating and Deleting Storage Volumes” on page 380
Creating and Deleting Storage Pools
For Engenio, 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 Engenio 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 Engenio storage system:
