I have a HP StorageWorks MSA2312i Dual Controller Modular Smart Array and a second enclosure.
I have four vdisks:
- vd01 (RAID5) (Current Owner A)
- vd02 (RAID5) (Current Owner B)
- vd03 (RAID10) (Current Owner A)
- vd04 (RAID10) (Current Owner B)
With two volumes per vdisk (vd01_001, vd01_v002 and so on)
The problem is that while Xen can see all the volumes in vd01 and vd02 (whose main controllers are A and B respectively), Xen cannot see any other volumes from vd03 and vd04.
EDIT2: If I add the disks of the second enclosure to a vdisk with disks of the first enclosure, I can see the new space, as workaround.
