Creating The Initial Snapshot Virtual Disk - Dell PowerVault MD3220 Cli Manual

3 Remove the drive letter(s) of the source in Windows or unmount the
virtual drive(s) in Linux to help guarantee a stable copy of the drive for the
Snapshot. If this is not done, the snapshot operation reports that it has
completed successfully, but the snapshot data is not updated properly.
NOTE:
clicking the Summary tab and then clicking the Disk Groups & Virtual
Disks link.
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.
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.
After your server has been prepared, see "Creating the Initial Snapshot Virtual
Disk" on page 66.

Creating the Initial Snapshot Virtual Disk

After first preparing the host server(s) as specified in the preceding procedure,
use the following examples to make a virtual disk snapshot.
The following syntax is the general form of the command to create a snapshot
virtual disk:
create snapshotVirtualDisk sourceVirtualDisk=
"sourceVirtualDiskName" [repositoryRAIDLevel=(0 |
1 | 5) (repositoryPhysicalDisks=
(enclosureID0,slotID0 ... enclosureIDn,slotIDn)
userLabel="snapshotVirtualDiskName"
warningThresholdPercent=percentValue
repositoryPercentOfSource=percentValue
repositoryUserLabel="repositoryName"
repositoryFullPolicy=(failSourceWrites |
failSnapShot)] [enclosureLossProtect=(TRUE | FALSE)]
NOTE:
Use one or all of the optional parameters as needed to help define your
configuration. You do not, however, need to use any optional parameters.
