About this task
Configuring a RAID array applies to a compute node in which disk drives or solid-state drives are
installed.
Note:
When configuring a RAID array, the hard disk drives must use the same type of interface and
must have identical capacity and speed.
Disk drives and solid-state drives in the IBM Flex System p270 Compute Node can be used to implement
and manage various types of RAID arrays in operating systems that are on the ServerProven list. For the
compute node, you must configure the RAID array through the
smit sasdam
utility, which is the SAS
RAID Disk Array Manager for the AIX operating system. The AIX Disk Array Manager is packaged with
the Diagnostics utilities on the diagnostics CD. Use the
smit sasdam
utility to configure the disk drives
for use with the SAS controller. For more information, see http://publib.boulder.ibm.com/infocenter/
systems/scope/hw/index.jsp?topic=/p7ebj/sasusingthesasdiskarraymanager.htm.
Important:
Depending on your RAID configuration, you might have to create the array before you install
the operating system in the compute node.
Before you can create a RAID array, you must reformat the drives so that the sector size of the drives
changes from 512 bytes to 528 bytes. If you later decide to remove the drives, delete the RAID array
before you remove the drives. If you decide to delete the RAID array and reuse the drives, you must
reformat the drives so that the sector size of the drives changes from 528 bytes to 512 bytes.
