We got a call today. Something we've never seen before. It looks like the IT has not added any DC outside the Hyper-V R2 cluster (failover cluster ion Windows 2008 R2)
During an electric failure in their office both hosts went down. Off lcourse all DCs (VMs part of the cluster) are down now.
As far as I know Windows failover cluster must access the Active directory to operate. Is there something we can do to get at least the DCs back online ?
I've been trying to start the VM from the hyper-v manager (saved-critical) but I got "failed to restor virtual machine state".
I can access the cluster through the IP, but it doesn't help much. I can read the warning "The cluster network name is not online". As no Dc are available the name can not been used (no DNS)
And guess what? All VMs but SCVMM were managed from SCVMM.
From the failover cluster I've been trying to restart the VMs But I had no much success
The disks (iSCSI SAN) storage and CSV are still online. But I'm unable to start any VM
Any advice is welcomed.
