Hyper VMM - Fails to start -> VMM cannot complete the WMI operation on server <server-name> because of error: [MSCluster_Resource.Name="<vm-name>"] The group or resource is not in the correct state to perform the requested operation


  • Running into a random issue, that impacts a couple of our virtual machines.  First our setup:

    3 Host Cluster - 2 * Dell PowerEdge R710 and 1 720.  Connected to Equal Logic SAN.  Running in a CSV.  All servers have latest BIOS/Firmware for NICs.  They are all running 2008 R2 Datacenter with SP1, and fully patched as of last week.

    Symptom ->  When restarting a VM on a host, it will shut down, and then fail with the error listed in the question.  Looking at Event Logs, it indicates it "Failed to open Attachment" points to C:\ClusterStorage\Volume# and the location of the VM/VHD.  Second part of the error "A Device attached to the system is not functioning".

    We have already tried the FSdepends fix on all the Host Servers.  We have also removed all A/V software from the hosts.

    The fix I am using right now, is via SCVMM.  I "migrate storage" to another Host, and then migrate the VM.  The VM ALWAYs will start up again - until the next time I have to do a shut down.  Then I have to migrate the storage, and repeat.  I have 3 or 4 VM's that will do this, regardless of what host they are on.  It is the migrate storage that corrects the issue - if I just migrate the VM, it will not start.

    I am at a loss - ?
