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 | 6) repositoryPhysicalDiskCount= numberOfPhysicalDisks physicalDiskType=(SAS) 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; 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. The following table lists the parameters and descriptions of what the parameters do. Table 11. Snapshot Virtual Disk Parameters Parameter Description physicalDiskType Specifies the type of physical disk to use for the snapshot repository virtual disk. The type must be specified as Serial Attached SCSI (SAS). This parameter works only with the count-based repository method of defining a snapshot virtual disk. 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 virtual disk. freeCapacityArea Specifies the amount of storage space to use for the snapshot repository virtual disk. Free storage space is defined in units of bytes, kilobytes, megabytes, or gigabytes. 50
