Pinned topic Mixed AIX versions in a GPFS cluster ( AIX 5.3 & 6.1 - GPFS 3.4)

‏2012-10-21T11:59:57Z |
Currently I am working on a project to expand a GPFS cluster running on version 3.4. The existing & quorum nodes are running on AIX 5.3 TL08 and the new nodes are running on AIX 6.1 and we are not in a position to migrate the OS on the exiting nodes at this point of time.

I know that GPFS 3.4 supports both the versions but IBM never recommends to mix up the OS versions. So, just wondering how the cluster will behave after I include the new nodes into the cluster running on the higher level of OS.

It would be a great help if someone have ever come across this kind of situation and ready to share their experience.

    I've run GPFS mixed with various AIX levels, no problems. There are occasional AIX-specific issues:

    AIX 5.3, 6.1 and even 7.1 nodes in the cluster at the same time (with V3.4).
    V3.5 doesn't support AIX 5.3.

    Hi Glen,

    Sounds good. Currently we are in process of completing the prep work, I will keep you guys updated.

    BTW, do you have any mixed OS versions withing the quorum group ?
