Editing Proliant SSA Command Examples (section)

== Create Logical Drives ==
This command will take all unnasigned drives and create RAID 0 logical drives for each of them
 ssacli ctrl slot=0 create type=arrayr0 drives=allunassigned

To create a single logical drive, use this command
 ssacli ctrl slot=0 create type=ld drives=1I:1:1

'''''NOTE''''' the order of the logical drives in the HP SSA output will determine the ordering for the SCSI device numbers in Linux, and will affect the drive letters assigned.  Deleting logical drives will shift all the subsequent drive assignments up, so '''be careful'''.  Using UUID tags instead of drive letters when specifying mounts is preferred for this reason.  Storage systems that directly manage drives should already use a drive serial to identify and order its disks, but '''if strange stuff happens, you have been warned'''.

You will need to get the drive numbers from the show command above.
