Dell PowerVault MD3620f - User-Defined Parameters

72 Using the Snapshot Feature
The command in this example creates a new snapshot repository virtual disk
that consists of three physical disks. The three physical disks comprise a new
disk group with a RAID level of 5. This command also takes a snapshot of the
source virtual disk, which starts the copy-on-write operation.
The following example is the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4" repositoryRAIDLevel=5
repositoryPhysicalDiskCount=3;
User-Defined Parameters
Parameters for the create snapshotVirtualDisk command enable you to
define the snapshot virtual disk to suit the requirements of your storage array.
Table 4-3 lists the parameters and descriptions of what the parameters do.

repositoryDiskGroup Specifies the disk group in which to build the snapshot
virtual disk. Default builds the snapshot repository
virtual disk in the same disk group as the source
