On a Windows 2008R2 server, I am getting this message in Event Viewer:

However, there is no disk 11 on this server. The disks stop at 10.

disk management mmc showing disks 9, 10, and the DVD drive

This particular server is a Hyper-V host in a cluster. All of the disks are either CSV disks or pass-through disks, all backed by iSCSI.

How can I identify which drive this is?

wmic does not list the drive:

Has there never been a disk 11? That error is usually caused by an unclean dismount. –  Nathan C Jul 8 '13 at 14:45
    
I have no idea. Do you know how to find out? Perhaps by snooping through the registry? –  longneck Jul 8 '13 at 16:14
    
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP might be a place to look. You can also try "wmic diskdrive list brief" from cmd –  dusan.bajic Jul 9 '13 at 16:37
    
@dusan.bajic no joy on either. –  longneck Jul 9 '13 at 17:02

This is a bit of a WAG but have you tried recompiling the iSCSI MOF files? I've come across similar behavior where NetApp's SnapDrive can't enumerate all the of the iSCSI drives on a particular server. This blog pointed me at this KB2001997.

Try comparing the results of the following WMI query on this server to another known good one:

Get-WmiObject -NameSpace Root\WMI MSiSCSIInitiator_PersistentDevices
