Today I was getting errors in my vCenter task bar complaining about Wipe an Flex-SE Virtual disk:
Wipe an Flex-SE virtual disk vmPC-019 A general system error occurred:
Wipe Disk failed: Failed to complete wipe operation.
Turns out vRanger Backup Solution had enabled Change Block Tracking for these VMs and vmWare doesn’t like that! Right click and disable change block tracking for the View VMs and you will no longer get the errors.
I used http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2039907 to help me figure out what was going on.
