Configuring A Sas Raid Array; Updating Ibm Director - IBM BladeCenter JS21 Types 8844 Service Manual

Configuring a SAS RAID array

Configuring a SAS RAID array applies to a blade server in which two SAS hard disk
drives are installed.
Two SAS hard disk drives in the blade server can be used to implement and
manage RAID level-0 and RAID level-1 arrays in operating systems that are on the
ServerProven list at http://www.ibm.com/servers/eserver/serverproven/compat/us/.
For the blade server, you must configure the SAS RAID array using the Standalone
Diagnostics CD.
Important: Depending on your RAID configuration, you must create the array
before you install the operating system in the blade server.
Before you can create a RAID array, you must reformat the hard disk drives so that
the sector size of the drives changes from 512 bytes to 528 bytes. If you later
decide to remove the hard disk drives, delete the RAID array before you remove
the drives.
