After you have used a Virtual Storage Console for VMware vSphere attach operation to retrieve the files you need, you can disconnect the virtual disks that contained the files by performing a VSC detach operation. The detach operation checks VSC to see whether there are attached virtual disks. It displays the ones it finds and gives you the option to detach them.
Your system must be running clustered Data ONTAP 8.2.2 or later.
You must have registered VSC with SnapCenter.
You must have attached disks using a VSC attach operation.
