This post just as a follow-up for thread HACMP 5.4 with AIX 5300-10 not working: 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 with (at least) AIX 5.3 from TL6 to TL12 (did not try older oslevels but found a post that could imply the problem did not exist at and below TL5) and RSCT 2.4.13.0
Problem with HACMP 5.4.1 shows as
Using an empty or a manually edited cluster rhosts does not make any difference but leads to the same error.
Now, this is fixed with (at least) SP10 for HACMP 5.4.1 (did not try older HA Service Packs). I could not find an APAR with a suitable description. Maybe it was related to IZ70306: CLCOMD HACMPNETWORK MALLOC MEMORY LEAK CAUSES CLCOMDES FAILURES which dates to 2010-09-06. I am not sure about that as during my tests I never saw the 5901 ODM error mentioned in the description but it also says that the clcomdES dies after "few verification invocations" and there are verification checks during Assistant run and the bug caused an incomplete cluster rhosts setup which led me to identify clcomdES as the culprit.
Hello AIX experts,
I have few queries and appreciate if you could help me with them.

HACMP two-node cluster with mirrored LVM.
HACMP two-node cluster with two SAN storages mirrored using LVM. Configured 2 disk heartbeat networks - 1 per each SAN storage. While performing redundancy tests. Once one of SAN storage is down - cluster is going to ERROR state. What are the guidelines... (2 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)
Setting up HACMP 6.1 on a two node cluster. The other node works fine and can start properly on STABLE state (VGs varied, FS mounted, Service IP aliased). However, the other node is always stuck on ST_JOINING state. Its taking forever and you can't stop the cluster as well or recover from script... (2 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 have a running HACMP Cluster with two nodes. Its working in active/passive mode. (i.e Out of the two nodes in the cluster one will be active and the other one will be on standby. If first node fails the other takes over)
1. There is a Service IP associated with the cluster. Now the... (2 Replies)
Hi,
Is it possible to have a Solaris cluster of 2 nodes at SITE-A using SVM and creating metaset using say 2 LUNs (on SAN). Then replicating these 2 LUNs to remote site SITE-B via storage based replication and then using these LUNs by importing them as a metaset on a server at SITE-B which is... (0 Replies)

Hi Guys,
I have to design a multinode hacmp cluster and am not sure if the design I am thinking of makes any sense.
I have to make an environment that currently resides on 5 nodes more resilient but I have the constrain of only having 4 frames. In addition the business doesnt want to pay for... (7 Replies)
Hi Guys,
I have two nodes clustered. Each node is AIX 5.2 & they are clustered with HACMP 5.2. The mode of the cluster is Active/Passive which mean one node is the Active node & have all resource groups on it & the 2nd node is standby.
Last Monday I noted that all resource groupes have been... (2 Replies)
