descriptions of Snapshot Virtual Disk.

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
