PowerHA for AIX

  • 1.  Update AIX SP in PowerHA cluster using NIM

    Posted Sat November 26, 2022 09:02 AM
    Hello,

    I have a simple PowerHA setup with 2 nodes in a cluster. There's just one resource group with the service IP and a volume group.

    I want to update AIX from 7200-05-03 to 7200-05-04.

    What is the recommended procedure for running a NIM update_all on a NIM client which is a PowerHA cluster node?

    I have 2 separate clusters, UAT and Prod, so I will be using the UAT cluster to test the AIX update process.

    Thanks
    Glenn

    Hello Glenn,
    PowerHA rolling migration process can be used here.


    Steps mentioned at:

    Thanks,

    Hello,

    Thanks for this but I'm referring to updating AIX nor PowerHA.

    I'm after a procedure to take me from AIX 7200-05-03 to AIX 7200-0504.

    My assumption is that I:


    1. End cluster services on the passive node
    2. Update AIX on the passive node
    3. Reboot AIX on the passive node
    4. Move the resource group from the active node to the update node
    Repeat the above for the second node which is now the passive node.

    Hello,
    Yes, those steps can be followed.
    In between step 4 and 5, start cluster services on passive node.
    If passive node also has RGs, then in the step1 stop PowerHA services with move RG option.
