I have an MD3200 SAS connected to two Poweredge R510 servers running Windows 2008.
Before upgrading one of the servers, both servers "saw" (in Disk Management) three disks matching the three virtual disks I'd created on the SAS (disk0 is/was the internal disk of the servers):
- disk1 (2 GB)
- disk2 (1,8 TB)
- disk3 (1,8 TB)
So far so good. Then I upgraded one of the two servers from Windows 2008 to Windows 2008 R2 without reinstalling.
After the upgrade, on the machine that is now running R2, when I open Disk Management I see this:
- disk1 (offline, unknown, 20 MB)
- disk2 (offline, unknown, 20 MB)
- disk3 (2 GB)
- disk4 (1,8 TB)
- disk5 (1,8 TB)
So I have these two "ghost" disks. Based on diskpart output, these disks should be the two virtual disks appearing in Modular Disk Storage Management as "Access virtual disks", mapped to LUN 31.
I understand these disks are needed and created by default. What I don't understand is why I now see them in Disk Management on the machine that has been upgraded to 2008 R2 (the other machine, still running 2008, does not see them in Disk Management).
Is this by design? Is this a problem, if so how do I fix it?
I haven't (yet) reinstalled MDSM on the 2008 R2 machine, do you think it could fix the issue?
Thanks
