Finally i found a "solution" to my problem: install a even newer version. As it seems the version i used was somewhat differently abled, as i believe the politically correct euphemism for "buggy" is. (A big THANK YOU goes to IBM for letting me do the beta-testing of software i thought to have purchased. I only bought a cluster-software but got a built-in adventure game at no cost.)
Here is what i did: first, install the latest AIX release (AIX 7.1, TL3 SP3):
This i did on both nodes. I am not sure if this was necessary, but together with the other changes (see below) it did the job. Next was to update the cluster software itself:
After this (and of course a reboot) i did a final cluster verification, then started the cluster without any problems. SNMP (and, as far as i can see, everything else) was working as expected. All in all it took me about 25 minutes per node, most of it can be done in parallel if the cluster can be stopped. Plan about 30-60 minutes for the whole update if you have the resources ready from the NIM server and everything else working.
Hello,
I was wondering if I have 3 nodes (A, B, C) all configured to startup with HACMP, but I would like to configure HACMP in such a way:
1) Node B should startup first. After the cluster successfully starts up and mounts all the filesystems, then
2) Node A, and Node C should startup !

This post just as a follow-up for thread https://www.unix.com/aix/115548-hacmp-5-4-aix-5300-10-not-working.html: there was a bug in the clcomdES that would cause the Two-Node-Cluster-Configuration-Assistant to fail even with a correct TCP/IP adapter setup. That affected HACMP 5.4.1 in combinatin... (0 Replies)

Hi,
I have a IBM Power series machine that has 2 VIOs and hosting 20 LPARS.
I have two LPARs on which GPFS is configured (4-5 disks)
Now these two LPARs need to be configured for HACMP (PowerHA) as well.
What is recommended? Is it possible that HACMP can be done on this config or do i... (1 Reply)
Hi
I'm a little rusty with HACMP, but wanted to find out if it is possible to remove a disk heartbeat network from a running HACMP cluster.
Reason is, I need to migrate all the SAN disk, so the current heartbeat disk will be disappearing. Ideally, I'd like to avoid taking the cluster down to... (2 Replies)
As i have updated a lot of HACMP-nodes lately the question arises how to do it with minimal downtime. Of course it is easily possible to have a downtime and do the version update during this. In the best of worlds you always get the downtime you need - unfortunately we have yet to find this best of... (4 Replies)
Hi,
A customer I'm supporting once upon a time broke their 2 cluster node database servers so they could use the 2nd standby node for something else. Now sometime later they want to bring the 2nd node back into the cluster for resilance. Problem is there are now 3 VG's that have been set-up... (1 Reply)
Hi all,
I remember way back in some old environment, having the HA cluster services not being started automatically at startup, ie. no entry in /etc/inittab.
I remember reason was (taken a 2 node active/passive cluster), to avoid having a backup node being booted, so that it will not... (4 Replies)
