How to offline a volume in Windows Server

I wanted to offline a volume so I could remove HD from virtual servers. Found this command:

mountvol E: /p

Worked well.

VM will not power on

One of my VMs would not power up. The error it was giving was:

"Cannot open the disk '/vmfs/volumes/......vmdk' or one of the snapshot disks it depends on. Reason: Argument list too long."

I went into "Edit Settings" for the VM and found that hard disk 2 was referencing was not valid, an empty file. I removed the hard disk, and re-added the hard disk, but pointing to the correct VMDK file.

After that the VM started up just fine.
