Online re-configuration of HB ip

Janne_5 — Fri, 03 Oct 2008 14:43:36 GMT

Does anyone know if I can change my heartbeat ip while the cluster is running? I got hp-ux 11.11 with ServiceGuard A.11.15.00.

I know it's possible in A.11.18 but I don't think that version is released for hp-ux 11.11.

I have one hb going over production lan and an other one over a dedicated hb lan.

I want to change the dedicated hb lan ip.

No, you cannot do this online with SG A.11.15.
You also need to know that SG A.11.15 is no longer supported

Just remember that if it's network or timing you probably have to stop the cluster. Especially on those versions.

11.16 is the last one for 11.11
Tip:
If your at 11.16 or lower version, you don't want to do a rolling upgrade to the higher versions. Because if you mix up the versions in your cluster, you can't make ANY changes to anything in that cluster till all nodes are up to the same MC/SG version.

Version 11.17 forward is strictly NON 11.11 backwards compatible.

You can get up to version 11.16 for HPUX 11.11.

Rgrds,
