Parameter Description
virtual disk. To enforce enclosure loss protection,
set this parameter to TRUE. The default setting is
FALSE.
physicalMediaType The type of physical disk media that you want to
use for the disk group. Valid physical disk media
consists of:
• HDD—Use this option when you have hard
physical disks in the expansion enclosure.
• SSD—Use this option when you have solid state
physical disks in the expansion enclosure.
• unknown—Use if you are not sure what types of
physical disk media are in the expansion
enclosure.
• allMedia—Use this option when you want to
use all types of physical disk media that are in
the expansion enclosure.
Use this parameter when you use the
repositoryPhysicalDiskCount parameter.
You must use this parameter when you have more
than one type of physical disk media in your
storage array.
physicalDiskType The type of physical disk that you want to use in
the virtual disk. You cannot mix physical disk types.
You must use this parameter when you have more
than one type of physical disk in your storage array.
The valid physical disk type is SAS. You must
specify a physical disk type. Use this parameter
when you use the
repositoryPhysicalDiskCount parameter.
freeCapacityArea The index number of the free space in an existing
disk group that you want to use to create the
snapshot (legacy) repository virtual disk. Free
capacity is defined as the free capacity between
existing virtual disks in a disk group. For example, a
disk group might have the following areas: virtual
disk 1, free capacity, virtual disk 2, free capacity,
virtual disk 3, free capacity. To use the free
capacity following virtual disk 2, you specify:
freeCapacityArea=2
Use the show diskGroup command to determine
if free capacity area exists.
warningThresholdPercent The percentage of repository capacity at which
you receive a warning that the snapshot (legacy)
repository is nearing full. Use integer values. For
example, a value of 70 means 70 percent. The
default value is 50.
