MSA2040 SAS Expand RAID6

Hi,

 

we have a MSA 2040, latest Firmware with 2 SAS Controller.

 

We created a RAID6 (Virtual) using 6 Drives. Now, we added Drive 7 and want to expand the Array with the 7th Disk.

 

I can't find an option to expand the RAID, do you have any hint?

Issue: unable to add disks to the disk group.

Please check page number 39 and 40. You will see following:

Page number 39
Note Disk Group Expansion is not supported with Virtual Storage. If you have Virtual Storage and are running out of storage space, the procedure to get more storage space would be to add another Disk Group to a pool.


Page number 40:
Note Disk Group Expansion is only available when using Linear Storage. During Disk Group expansion, other disk utilities are disabled. These utilities include Disk Group Scrub and Rebuild

Hope this helps
