18.To confirm that the upgrade was a success, type 
lscfg -vl pdiskX
 where X 
is 0,1... for all SSA disks. Check the ROS Level line to see that each disk 
has the appropriate microcode level (for the correct microcode level see 
the above mentioned web-site).
3.3.1.4  Configuring a RAID on SSA Disks
Disk arrays are groups of disk drives that act like one disk as far as the 
operating system is concerned, and which provide better availability or 
performance characteristics than the individual drives operating alone. 
Depending on the particular type of array that is used, it is possible to 
optimize availability or performance, or to select a compromise between both.
The SSA Enhanced Raid adapters only support RAID level 5 (RAID5). RAID0 
(Striping) and RAID1 (Mirroring) is not directly supported by the SSA 
Enhanced Raid adapters, but with the Logical Volume Manager (LVM), RAID0 
and RAID1 can be configured on non-RAID disks. 
In order to create a RAID5 on SSA Disks, use the command 
smitty ssaraid
This will show you the following menu:
Select Add an SSA RAID Array to do the definitions.
