A device driver and a set of utilities must be
installed so that the controller can be identified and configured
by Linux.
Common IBM SAS RAID controller tasks
The instructions in this set of topics pertain to the various
tasks that can be performed to manage disk arrays. The interface for
working with the IBM SAS RAID
controller is iprconfig.
Multi-initiator and high availability
You can increase availability using multi-initiator and
high availability to connect multiple controllers to a common set
of disk expansion drawers.
IBM SAS RAID controller maintenance
Maintenance procedures include microcode updates, failure
recovery procedures, and working with the battery pack.
Problem determination and recovery
Several tools are available that the trained service representative
