HP P6000 Command view - Disk Group Issue

[RBCCV]

Greetings,

i have 2 EVA4400 with several enclosures and disk groups configured.

One of the disk groups has 12 Disks (8x146GB and 4x450GB).

The P6000 command view eva shows the following properties for this disk group:

Summary:

Total: 1785 GB
Allocated: 990 GB
Allocation level: 55 %
Requested: 989 GB
Oversubscribed: 0 GB

Since there is about 45% of non allocated space, it shoud had more space available that indicated (see attachment)

Available (estimated)

Vraid0: 5 GB
Vraid1: 0 GB
Vraid5: 2 GB
Vraid6: Not available

What seems to be the problem, any help ?
I cannot create any VDisk greater than 5 GB( Vraid0) .
Best regards,

[Cali]

I can see a Hardware Warning.

May be you have some failed Disks?

From the screenshot you have protection level set to single. With 450GB disks in the group you will have reserved 900GB, two x largest disk. This is reserved for disk failures and is not available to allocate to Vdisks.  This is one of the reasons why it is not good to mix capacities in a group. Also the 450GB disks will be hot spots as they will get 3 writes for each write to a 146GB disk.
