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.
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.
repositoryUserLabel Specifies the name to give to the snapshot repository
virtual disk. If you do not choose a name for the snapshot
repository 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 an associated snapshot repository
virtual disk, the default snapshot repository virtual disk
name is Mars_Spirit_4
‑R1. If the source virtual disk
already has n – 1 number of snapshot repository virtual
disks, the default name is Mars_Spirit_4 ‑Rn.
warningThresholdPercent Specifies how full to allow the snapshot repository virtual
disk to get before sending a warning that the snapshot
repository virtual disk is close to capacity. The warning
value is a percentage of the total capacity of the snapshot
repository virtual disk. The default value is 50, which
represents 50 percent of total capacity. (Change this value
using the set snapshotVirtualDisk command.)
repositoryPercentOfSource Specifies the size of the snapshot repository virtual disk as
a percentage of the source virtual disk size. The default
value is 20, which represents 20 percent of the source
virtual disk size.
repositoryFullPolicy Specifies how snapshot processing continues if the
snapshot repository virtual disk is full. You can choose to
