Dell PowerVault MD3420 - Manual (Page 237)

Parameter Description
virtual disk name has special characters, you must
also put quotation marks (" ") around the virtual
disk name.
userLabel Name of the snapshot virtual disk. You must put
quotation marks (" ") around the snapshot virtual
disk name. If you enter more than one snapshot
virtual disk name, this command fails.
warningThresholdPercent Percentage of repository capacity at which you
receive a warning that the repository is nearing full.
Use integer values. For example, a value of 70
means 70 percent. The default value is 50 percent.
NOTE: If warningThresholdPercent is not
specified, the previously set value is used.
repositoryFullPolicy Specifies how snapshot processing continues if the
repository is full. You can choose to fail writes to
the source virtual disk (failSourceWrites) or fail
writes to the snapshot virtual disk
(failSnapShot). The default value is
failSnapShot.
NOTE: If repositoryFullPolicy is not
specified, the previously set value is used.
Additional Information
NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the
names. Command names can have a maximum of 30 characters. If you exceed the maximum
character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation.
You can recreate a single snapshot virtual disk or multiple snapshot virtual disks with optional parameters:
• If you specify one or more of the optional parameters, the re-create operation processes each
snapshot virtual disk separately.
• If you try to use the same user label for more than one virtual disk, the command fails.
• If you do not set the warningThresholdPercent parameter or the repositoryFullPolicy
parameter, values that you previously set are used.
You can recreate multiple snapshot legacy virtual disks without optional parameters:
• If you list multiple snapshot legacy virtual disks to be re-created but do not specify any of the optional
parameters, the re-create operation processes the snapshot virtual disks as a batch process.
• Validation checks for the necessary snapshot-restarted preconditions are performed before restarting
any snapshot. If any of the listed snapshot virtual disks fail the validation, the entire command fails and
the snapshot virtual disks are not re-created. If the validation is successful for all of the snapshot
virtual disks in the list, but one or more of the snapshots in the list fails to restart, the entire command
fails and none of the snapshots are re-created.
• During snapshot re-creation, all affected virtual disks (snapshots, base, and repository) are
appropriately quiesced and I/O operations are resumed to all affected virtual disks after all snapshots
have been successfully re-created.
