Define the capacity of a snapshot repository virtual disk as any percentage of the size of the source virtual disk. A value of 20 percent is a good compromise between size and speed. In the previous example, the size of the snapshot repository is set to 4 GB. The underlying assumption is that the source virtual disk size is 20 GB (0.2 x 20 GB = 4 GB). The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4" repositoryDiskGroup=2 freeCapacityArea=2; 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 | 6) 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;" Using the Snapshot Feature 69
