Using The Create Logicaldrive Command; Creating Logical Drives With User-Assigned Disk Drives - IBM System Storage DS3000 Programming Manual

v validate storageSubsystem securityKey
And these commands are about Full Disk Encryption (FDE):
v start secureErase (drive | drives)
v enable subsystem [subsystemName] security
v create hostPort identifier
Note: Firmware version 07.50 adds the securityType parameter.
Example of the Auto Configuration Command
c:\...\...\client>smcli 123.45.67.89 -c "autoConfigure
storageSubsystem driveType=fibre raidLevel=5 subsystemWidth=8
subsystemCount=3 logicalDrivesPersubsystemCount=4 hotSpareCount=2
segmentSize=8 cacheReadPrefetch=TRUE securityType=none T10PI=none;"
The command in this example creates a storage subsystem configuration by using Fibre Channel disk
drives set to RAID level 5. Three subsystems are created, and each subsystem consists of eight disk
drives, which are configured into four logical drives. The storage subsystem has two hot spares. The
segment size for each logical drive is 8 KB. The cache read prefetch is turned on, which causes additional
data blocks to be written into the cache.
T10PI protection
T10PI protection checks and corrects errors that might occur as data is communicated between a host and
a storage subsystem. Thus, enabling this feature for a new logical drive ensures that errors are detected
and corrected. To enable T10PI, storage subsystem must support T10PI and the disk pool must be T10PI
capable.

Using the Create LogicalDrive Command

Use the create logicalDrive command to create new storage subsystem logical drives in three ways:
v Create a new logical drive while simultaneously creating a new subsystem to which you assign the
disk drives
v Create a new logical drive while simultaneously creating a new subsystem to which the Storage
Manager software assigns the disk drives
v Create a new logical drive in an existing subsystem
You must have unassigned disk drives in the subsystem. You do not need to assign the entire capacity of
the subsystem to a logical drive.

Creating Logical Drives with User-Assigned Disk Drives

When you create a new logical drive and assign the disk drives you want to use, the Storage Manager
software creates a new subsystem. The controller firmware assigns an subsystem number to the new
subsystem. The command takes this form:
create logicalDrive drives=(enclosureID1,slotID1...enclosureIDn,slotIDn)
raidLevel=(0 | 1 | 3 | 5 | 6) userLabel=logicalDrivesName
[capacity=logicalDrivesCapacity] [owner=(a | b)
cacheReadPrefetch=(TRUE | FALSE)
segmentSize=segmentSizeValue]
enclosureLossProtect=(TRUE | FALSE)
securityType=(none | capable | enabled) T10PI=(none|enabled)]
Note: The capacity parameter, the owner parameter, the cacheReadPrefetch parameter, the segmentSize
parameter, and the enclosureLossProtect parameter are optional parameters (indicated by the items
