Creating The Snapshot Using The Advanced Path - Dell PowerVault MD3220 Owner's Manual

4 Follow any additional instructions for your operating system. Failure to
follow these additional instructions can create unusable snapshot virtual
disks.
NOTE:
If your operating system requires additional instructions, you can find those
instructions in your operating system documentation.
After your host server has been prepared, see "Creating a Snapshot Virtual
Disk Using the Advanced Path" on page 140 to create the snapshot using the
advanced path.
If you want to use a snapshot regularly, such as for backups, use the Disable
Snapshot and Re-create Snapshot options to reuse the snapshot. Disabling
and re-creating snapshots preserves the existing virtual disk-to-host mappings
to the snapshot virtual disk.

Creating the Snapshot Using the Advanced Path

Removing the drive letter of the associated virtual disk in Windows or
unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive
for the Snapshot.
