Snapshot Virtual Disk Parameters

Parameter

Description

physicalDiskType

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.

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.

userLabel

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.
