Creating A Snapshot Virtual Disk With Software-Assigned Physical Disks - Dell PowerVault MD3620f Command Line Interface Manual

Creating a Snapshot Virtual Disk with Software-Assigned Physical
Disks
This version of the create snapshotVirtualDisk command lets you choose an
existing disk group in which to place the snapshot repository virtual disk. The
storage management software determines which physical disks to use. You can
also define how much space to assign to the repository virtual disk. Because
you are using an existing disk group, the RAID level for the snapshot virtual
disk defaults to the RAID level of the disk group in which you place it. You
cannot define the RAID level for the snapshot virtual disk. The general syntax
for this command is:
create snapshotVirtualDisk sourceVirtualDisk=
"sourceVirtualDiskName" [repositoryDiskGroup=
diskGroupNumber freeCapacityArea=
freeCapacityIndexNumber 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 define your
configuration. It is not necessary to use any optional parameters.
The following example is a command in which software assigns the
physical disks:
client>smcli 123.45.67.89 -c "create
snapshotVirtualDisk sourceVirtualDisk=
\"Mars_Spirit_4\" repositoryDiskGroup=2
freeCapacityArea=2;"
The command in this example creates a new snapshot repository virtual disk
in disk group 2. The source virtual disk is Mars_Spirit_4. The size of the
snapshot repository is 4 GB. This command also takes a snapshot of the
source virtual disk, which starts the copy-on-write operation.
