Parameter Description
disk. To enforce enclosure loss protection, set this
parameter to TRUE. The default value is FALSE.
physicalDiskType
The type of physical disk that you want to use for
the replication repository 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.
Valid physical disk types are :
• SAS
If you do not specify a physical disk type, the
command defaults to SAS.
dataAssurance
The setting to specify that a disk pool has data
assurance protection to make sure that the data
maintains its integrity. When you use this
parameter, only protected physical disks can be
used for the disk pool.
These settings are valid:
• none – The disk pool does not have data
assurance protection.
• enabled – The disk pool has data assurance
protection. The disk pool supports protected
information and is formatted with protection
information enabled.
The default value is none.
Notes
If a value is entered for the repository storage space that is too small for the replication repository virtual
disks, the RAID controller module firmware returns an error message that indicates the amount of space
needed for the replication repository virtual disks. The command does not try to change the replication
repository virtual disk. The command can be re-entered using the value from the error message for the
repository storage space value.
When you assign the physical disks, if you set the enclosureLossProtect parameter to TRUE and have
selected more than one physical disk from any one enclosure, the storage array returns an error. If you
set the enclosureLossProtect parameter to FALSE, the storage array performs operations, but the
disk group that you create might not have enclosure loss protection.
When the RAID controller module firmware assigns the physical disks, if you set the
enclosureLossProtect parameter to TRUE, the storage array returns an error if the RAID controller
module firmware cannot provide physical disks that result in the new replication repository virtual disk
having enclosure loss protection. If you set the
enclosureLossProtect parameter to FALSE, the
storage array performs the operation even if it means that the replication repository virtual disk might not
have enclosure loss protection.
