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. The following
commands are related to the securtiy key:
•
create storageArray securityKey
•
set storageArray securityKey
•
start secureErase (physicalDisk | physicalDisks)
•
enable diskGroup [diskGroupName] security
Enclosure Loss Protection
For enclosure loss protection to work, each physical disk in a disk group must
be in a separate enclosure. 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. Enclosure loss
protection is not valid when you create virtual disks on existing disk groups.
