MSA 2042 Expand Disk-Group with only one HD

[UrsBreu]

Hello

I would like to expand a Disk Group online with an additional HD. Unfortunately I do not have more HD available.

# show vdisks

Depending on several factors, vdisk expansion can take a significant amount of time to complete. The size of the physical disks in the original vdisk, the amount of capacity being added, and the level of I/O activity during expansion will influence the time of completion.
It is strongly recommended to review the Best Practices white paper before starting a vdisk expansion. See the online help to access this white paper.
Are you ready to continue? (y/n) y

Unfortunately I always get the following error message

Error: The pool requested is of the wrong storage class.

Can someone please help me ?

Best regards

Hi,

MSA 2042 supports both linear vdisk and virtual Pools.

Disk groups created under Virtual Pool does not support disk group expansion where as linear vdisk could be expanded.

As per the command output shared the disk groups has been configured as part of virtual pool.

You can add only a new disk group to the Pool which requires a minimum of 2 hard drives.

Please refer to the System concepts topic in SMU guide for more information:
