Creating a disk array
A disk array is created using a set of Active Array Candidate
pdisks.
Migrating an existing disk array to a new RAID level
The SAS RAID controller supports migrating an existing
RAID 0 or 10 disk array to RAID 10 or 0, respectively. This allows
you to dynamically change the level of protection of a disk array
while preserving its existing data.
Deleting a disk array
To preserve the data on the disk array, you must first
back up all files in the logical volumes and file systems on the disk
array before removing the disk array from its volume group.
Adding disks to an existing disk array
The controller supports adding disks to existing RAID level
5 or 6 disk arrays, which allows you to dynamically increase the capacity
of a disk array while preserving its existing data.
Using hot spare disks
Hot spare disks are used to automatically replace a disk
that has failed in a redundant RAID environment.
AIX command-line interface
Many tasks used to manage the SAS RAID controller can be
performed by using the AIX command
line instead of using the SAS Disk Array Manager.
