enclosure, the storage subsystem returns an error. If you set the
enclosureLossProtect
parameter to
FALSE
, the storage subsystem performs operations, but the subsystem that you create might not have
enclosure loss protection.
Enclosure loss protection is not valid when you create logical drives on existing subsystems.
The
drawerLossProtect
parameter defines if data on a logical drive is accessible if a drawer fails. When
you assign the drives, if you set the drawerLossProtect parameter to TRUE and select more than one drive
from any one drawer, the storage subsystem returns an error. If you set the drawerLossProtect parameter
to FALSE , the storage subsystem performs operations, but the subsystem that you create might not have
drawer loss protection
You must set the
enclosureLossProtect
parameter and the
drawerLossProtect
parameter to the same
value. Both of the parameters must be either
TRUE
or
FALSE
. If the
enclosureLossProtect
parameter and
the
drawerLossProtect
parameter are set to different values, the storage subsystem returns an error.
Security Type
The
securityType
parameter is valid for drives that are capable of full disk encryption (FDE). With FDE,
the controller firmware can create a key and activate the Full Disk Encryption feature. The Full Disk
Encryption feature encrypts data as the data is written to the drive and decrypts the data as the data is
read from the drive. Without the key created by the controller, the data written to the drive is inaccessible
Before you can set the securityType parameter to capable or enabled, you must create a storage
subsystem security key. Use the create storageSubsystem securityKey command to create a storage
subsystem security key. These commands are related to the security key:
v
create storageSubsystem securityKey
v
enable subsystem [subsystemName] security
v
export storageSubsystem securityKey
v
import storageSubsystem securityKey
v
set storageSubsystem securityKey
v start secureErase (drive | drives)

Naming Conventions
Create Logical Drive on Disk Pool
This command creates a new standard RAID logical drive or a thin logical drive on an existing disk pool.
Note that some of the traditional logical drive creation parameters are left off because they have no
applicability to disk pools. Some of the parameters included in
create-raid-vol-attr-value-list
must
be ignored, or should cause an error if specified by the user.
Note: Some parameters for creating a standard RAID logical drive on an subsystem are not compatible
for creating logical drives of any type on a disk pool. When using older scripts to create logical drives on
disk pools, make sure that all of the parameters are valid for disk pools. Invalid parameters prevent the
scripts from running correctly and cause an error to be posted.
Syntax for Creating a Standard Logical Drive
create logicaldrive diskPool="diskPoolName"
userLabel="logicalDriveName"
capacity=logicaldriveCapacity
