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

This version of the create snapshotVirtualDisk command lets you choose an existing disk group to place the snapshot repository virtual disk. The MD 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)]
                                 

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.

The following example is the script file version of the command:

create snapshotVirtualDisk sourceVirtualDisk=
                                    "Mars_Spirit_4" repositoryDiskGroup=2
                                    freeCapacityArea=2;
