MC/ ServiceGuard can run on 2 nodes with different Version ??

[Anh.Quan]

Hi All,

I have 2 node with the same hardware configuration. but 1 node run on HP-UX 11.00, other run on HP-UX 11.11. Can i rebuild cluster with MC/SG on 2 node?

If it's possible. Do i have to configure with some more features??

Thanks!

Shalom Vu,

All nodes of a cluster MUST run with the same version of SG.

Take the node out of the cluster to configure enhancements.

No you cannot do this. The ONLY time nodes iun a cluster can run mixed OS versions is during a Rolling Upgrade.

What Steven says is correct, but I do not see how it answers the question!

All nodes in a cluster must run the same release of Serviceguard other than during a rolling upgrade. But you can run the same Serviceguard 11.14 release on HP-UX 11.0 and HP-UX 11.11 nodes within the same cluster.

Note that this is only true for HP-UX 11.0 and 11.11. It is not supported to run on any other mix of HP-UX releases within a single cluster.

Ah yes, forgot about the exception for A.11.14 of SG and 11.00 with 11.11 nodes.
But HP-UX 11.00 is out of support now

The idea with the rolling upgrade is when you do it.. YOur basic limitation is you cannot run cmapplyconf to make changes in your cluster while you are mixed and you want to run administrative commands

cmruncl, cmhaltnode, cmrunnode, cmmodpkg, cmrunpkg, cmhaltpkg etc..

only on the node with the latest version
