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:

  1. 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
