Parameter
Description
Valid values are highest, high, medium, low, and 
lowest. The default value is high.
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.
allocateReservedSpace
The setting to disable or enable the reserve 
capacity on the physical disk drive in a disk pool. 
The RAID controller module firmware 
automatically reserves additional capacity on each 
physical disk drive when creating a disk pool. To 
prevent the RAID controller module firmware from 
reserving additional capacity on each physical disk 
drive in a disk pool, set this parameter to FALSE. 
The default value is TRUE.
enclosureLossProtect
The setting to enforce enclosure loss protection 
when you create the disk pool. To enforce 
enclosure loss protection, set this parameter to 
TRUE. The default value is FALSE.
drawerLossProtect
The setting to enforce drawer loss protection 
when you create the disk pool. To enforce drawer 
loss protection, set this parameter to TRUE. The 
default value is FALSE.
Security Type
The securityType parameter is valid for physical disks that are capable of self encrypting disk (SED). 
With SED, the RAID controller module firmware can create a key and activate the physical disk security 
feature. The physical disk security feature encrypts data as the data is written to the physical disk and 
decrypts the data as the data is read from the physical disk. Without the key created by the RAID 
controller module, the data written to the physical disk is inaccessible.
Before you can set the securityType parameter to capable or enabled, you must create a storage array 
security key. Use the create storageArray securityKey command to create a storage array 
security key. These commands are related to the security key:
• create storageArray securityKey
• enable diskGroup [diskGroupName] security
