When ever backup tool tries to backup a VM it fails with an error :
Backup tool uses VCB.
ABC\ABC.vmdk Failed Failed to open disk
ABC\ABC_1.vmdk Failed Failed to open disk
ABC\[XXX-XXX-XX-XX-XXX] ABC/ABC_1_1.vmdk Failed Failed to open disk
ABC\[XXX-XX-XX-XX-XXX] ABC/ABC_1_1_1.vmdk Failed Failed to open disk
ABC\ABC_2_1.vmdk Failed Failed to open disk
ABC\ABC_3.vmdk Failed Failed to open disk
We tried to
1) Consolidate the Disk. Consolidation Successfull.
2) Restart VM.
3) Took a new snapshot and deleted it.
4) vMotion the VM.
Still at the time of backup same error occurs.
