Hello Folks,
I have recently been boggled yet again from Windows and failover cluster manager.
I have at the time of incident a 5 node cluster all running 2008 R2 Enterprise. I had one of my nodes become overwhelmed by having to many VM's running on it at the same time. During this hang up the host migrated all of the virtual machines to other hosts and killed its service. At which point I was able to restart and bring it back online.
Something happened during the migration of these VM's. When I was going to have them migrate back to the host they were just evacuated from all of them were missing there NIC's. I had to manually re-add the NICs to the virtual machines settings. What I didn't notice till a few days later is a VHD was completely gone from the configuration on the VM. Not only was it gone from the settings but the Clustered Shared Volume aswell.
The affected VM had three Drives attached to it via vhd's. C:, E: and D:. When I created the VHD I created the D:\ drive using an ISCSI controller because the two IDE controllers were already in use. Is this a bad thing because now this VHD file is completely gone along with 20GB of data it had residing of it. I do not have backups of my CSV's.
I am not looking to restore the data but simply figure out what caused this this thing to loose it's VHD file completely and to not have it happen again.
Thanks in advanced,
Eddie
