When I go into Edit Settings and add a Hard Drive choosing existing hard drive I get the following error:
Failed to add disk scsi0:1
Failed to power on scsi0:1
Reason: Failed to lock the file
Cannot open the disk '/vmfs/volumes....vmdk' or one of the snapshot disks it depends on
Some VMs I can. Until I get these others working I can't get my backup software working.
Why can't I add these?
