I have troubles making clstat work. All the "usual suspects" have been covered but still no luck. The topology is a two-node active/passive with only one network-interface (it is a test-setup). The application running is SAP with DB/2 as database. We do not use SmartAssists or other gadgets.
Here are the OS and HACMP-versions:
cldump works and all other cluster services are working as expected too. Alas, calling clstat:
I followed this procedure and double-checked everything mentioned there:
I also made sure the services are up and snmpd is the correct one:
The loopback-addresses for IPv6 are there in the /etc/hosts:
In the cited document it is mentioned to remove the comments in /etc/snmpdv3.conf as a last-ditch effort which i did. The services were restarted as described there and finally the whole system rebooted. I also did a cluster verification and synchronisation (in fact several times, before and after the reboot).
To be honest i am out of ideas what i still could do.
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)
