How do we increased available space in a volume on an MSA 1050 SAN?

We have an MSA 1050 SAN containing 10x 1.2TB drives in a RAID-6 configuration (single drive pool, single volume). We want to increase the disk space available in the volume and have done this on an MSA 1040 by simply adding disks to the disk group/pool and expanding the array, but this doesn't appear possible on the 1050. We want to avoid having to back up / wipe / reconfigure / restore the array if at all possible. How can we increase available disk space?

Thanks. Seems very odd to remove a feature that was available previously! We added 12 disks to the existing 10 in the end, creating a 10-disk RAID-6 volume and two global spares.

That's odd, with dual controllers you would normally add that many disks as a new disk group on the other controller. They like to have a balanced config with half of the disks owned be each controller before adding more.

I was not aware of the ability to add disk groups on different controllers. How would I tell which controller owns which disk group? I don't see it in the GUI,

To recap, we now have 10 disks in RAID-6 (Pool A, Disk Group dgA01, Vol001), another 10 disks in RAID-6 (Pool B, Disk Group dgB01, Vol002) and two global spares.

My bad, you don't have to set ownership it distributes disk groups automatically between the two controllers.

Storage information
The Storage A and Storage B blocks provide more detailed information about the logical storage of the system. The
Storage A block shows information about virtual pool A, which is owned by controller A. The Storage B block shows the
same types of information about virtual pool B.
