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. For the blade server, you must configure the SAS RAID array
through the optional ServeRAID Manager program.
The IBM ServeRAID Support CD contains the ServeRAID Manager program, which
you can use to configure the hard disk drives for use with the SAS controller. For
details about using these programs, see the documentation on the IBM ServeRAID
Support CD.
Important: Depending on your RAID configuration, you must create the array
before you install the operating system in the blade server. See the IBM ServeRAID
software matrix for more information.
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 MB to 528 MB. If you later decide to
remove the hard disk drives, delete the RAID array before you remove the drives.
If you decide to delete the RAID array and reuse the hard disk drives, you must
reformat the drives so that the sector size of the drives changes from 528 MB to
512 MB.
