enter a value for the cacheReadPrefetch parameter or the segmentSize parameter. If you do not enter a
value, the controller firmware uses the usageHint parameter with fileSystem as the default value.
Entering a value for the usageHint parameter and a value for the cacheReadPrefetch parameter or a
value for the segmentSize parameter does not cause an error. The value that you enter for the
cacheReadPrefetch parameter or the segmentSize parameter takes priority over the value for the
usageHint parameter.
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 set storageSubsystem securityKey
v import storageSubsystem securityKey
v export storageSubsystem securityKey
v start secureErase (drive | drives)
v enable subsystem [subsystemName] security
v create hostPort identifier

Create RAID Logical Drive (Manual Drive Select)
This command creates a new subsystem and logical drive and lets you specify the disk drives for the
logical drive.
Important: You cannot use mixed disk drive types in the same subsystem and logical drive. This
command fails if you specify different types of disk drives for the RAID logical drive.
Syntax
create logicalDrive drives=(enclosureID1,drawerID1,slotID1 ... enclosureIDn,
drawerIDn,slotIDn)
[subsystem=[subsystemName]]
raidLevel=(0|1|3|5|6)
userLabel="logicalDriveName"
owner=(a | b)
[capacity=logicalDriveCapacity
cacheReadPrefetch=(TRUE | FALSE)
segmentSize=segmentSizeValue
usageHint=(fileSystem | dataBase | multiMedia)
enclosureLossProtect=(TRUE | FALSE)
drawerLossProtect=(TRUE | FALSE)
dssPreAllocate=(TRUE | FALSE)
securityType=(none | capable | enabled)]
T10PI=(none | enabled)]
