HOWTO: Update AIX 6100-06/7100-00 when CAA is active |
|
|
Note that PowerHA SystemMirror 7.1 exploits the CAA technology in the AIX
Operating System and hence would require CAA cluster be stopped before the OS
updates.
AIX 6100-06/7100-00 delivered the first version of the Operating System embedded
cluster technology also called as Cluster Aware AIX (CAA). AIX releases later to these
technology levels have modified CAA significantly. Hence updating to these later AIX
levels from 6100-06 or 7100-00 requires that CAA based cluster be stopped from
operation before the OS update. This document provides guidelines to customers for such
an OS update procedure.
