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. Table 4-2 lists the parameters and descriptions of what the parameters do. Table 4-2. Snapshot Virtual Disk Parameters Parameter physicalDiskType repositoryDiskGroup freeCapacityArea userLabel Description Specifies the type of physical disk to use for the snapshot repository virtual disk. The choice is either Serial Attached SCSI (SAS) or Serial Advanced Technology Attachment (SATA). This parameter works only with the count-based repository method of defining a snapshot virtual disk. 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. 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. Specifies the name to give to the snapshot virtual disk. If you do not choose a name for the snapshot virtual disk, the RAID controller modules create a default name using the source virtual disk name. For example, if the source virtual disk name is Mars_Spirit_4 and it does not have a snapshot virtual disk, the default snapshot virtual disk name is Mars_Spirit_4-1. If the source virtual disk already has n - 1 number of snapshot virtual disks, the default name is Mars_Spirit_4-n. 70 Using the Snapshot Feature
