Using the Snapshot Feature

Creating a Snapshot Virtual Disk by Specifying a Number of Physical
Disks
With this version of the create snapshotVirtualDisk command, you must
specify the number of physical disks and the RAID level for the snapshot
repository virtual disk. This version of the
create snapshotVirtualDisk
command creates a new disk group. You must have physical disks in the
storage array that are not assigned to a disk group for this command to work:
create snapshotVirtualDisk sourceVirtualDisk=
"sourceVirtualDiskName" [repositoryRAIDLevel=(0 |
1 | 5) repositoryPhysicalDiskCount=
numberOfPhysicalDisks physicalDiskType=(SAS |
SATA) userLabel= "snapshotVirtualDiskName"
warningThresholdPercent= percentValue
repositoryPercentOfSource= percentValue
repositoryUserLabel=
"repositoryName"
repositoryFullPolicy=(failSourceWrites |
failSnapShot)] [enclosureLossProtect=(TRUE |
FALSE)]
NOTE:
Use one or all 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 users specify the number of
physical disks:
client>smcli 123.45.67.89 -c "create
snapshotVirtualDisk sourceVirtualDisk=
\"Mars_Spirit_4\" repositoryRAIDLevel=5
repositoryPhysicalDiskCount=3;"
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;
