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
In order to create a RAID5 on SSA Disks, use the command smitty ssaraid. This will show you the following menu:
