Upgrade AIX and powerha 6.1 on a two cluster node.
Posted on 2013-06-20
I've always upgrade powerha and AIX on nodes of a cluster OFFLINE, I mean, shutdown applications, stop cluster services, upgrade all software from nim, reboot and start again all applications, but now it's time to upgrade our PRODUCTION cluster and we want to do it with the less downtime possible.
The cluster is built with two nodes AIX 6100-07-04 and powerha 6.1 SP8 and we want to upgrade to AIX 6100-07-06 and powerha 6.1 SP10. I have read about the "rolling migration" but not sure how to do it that way. What we need is the less downtime possible.
