Configuration: Premium Feature—Snapshot Virtual Disks 143
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.
