Dell PowerVault MD 32XX/36XX Series Storage Arrays CLI Guide

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)]enableSchedule=(TRUE | FALSE) | schedule=
                                    (immediate | snapshotSchedule)]
                                 

See step 1 through step 4 in the preceding section, Preparing Host Servers To Create An Initial Snapshot Virtual Disk. The following example shows a command in which users assign the physical disks:

client>smcli 123.45.67.89 -c "create
                                    snapshotVirtualDisk sourceVirtualDisk=
                                    \"Mars_Spirit_4\" repositoryRAIDLevel=5
                                    repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);"
                                 

The command in this example creates a new snapshot of the source virtual disk Mars_Spirit_4. The snapshot repository virtual disk consists of five physical disks that form a new disk group. The new disk group has a RAID level of 5. This command also takes a snapshot of the source virtual disk, starting the copy-on-write operation.

See step 1 through step 4 in the preceding section, Preparing Host Servers To Create An Initial Snapshot Virtual Disk. The following example is the script file version of the command:

create snapshotVirtualDisk sourceVirtualDisk=
                                    "Mars_Spirit_4" repositoryRAIDLevel=5
                                    repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);
                                 

A minimal version of this command might look like the following example:

client>smcli 123.45.67.89 -c "create
                                    snapshotVirtualDisk sourceVirtualDisk=
                                    \"Mars_Spirit_4\";"
                                 

The command in this example creates a new snapshot for the source virtual disk Mars_Spirit_4. The repository virtual disk is created in the same disk group as the source virtual disk, which means that the repository virtual disk has the same RAID level as the source virtual disk. This command starts the copy-on-write operation.

Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Create An Initial Snapshot Virtual Disk. The following example is the script file version of the command:

create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4";
