serviceguard error renaming hosts

The following is from renaming hosts or changing their IP addresses in a SG cluster.  In addition to changing all the cluster configuration files (cmclnodelist, cluster ascii, package ascii and control files) from the old names to the new names, you also probably need to delete /etc/cmcluster/cmclconfig (the cluster binary config file).  The old IP address are "stuck" in there and cmcheckconf or cmapplyconf  won't proceed without deleting the cluster binary file.

If you don't delete it, here's the message you will receive when running cmapplyconf or cmcheckconf:

Checking nodes ... Done
Checking existing configuration ... Done
Warning: Unable to get configuration for cluster CLUSTER_NAME
Error: Node HOSTNAME is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
HOSTNAME through either file-based access (pre-A.11.16 version) or role-based
access (version A.11.16 or higher) and/or that the host name lookup
on node HOSTNAME resolves the IP address correctly.

single vs. dual core in HP-UX

Single-core processors ======================
processor family: 31 Intel(R) Itanium 2 Family Processors

Dual-core processors ====================
processor family: 32 Intel(R) Itanium 2 9000 series
processor family: 32 Intel(R) Itanium 2 9100 series

So, processor family 32 means dual core;  processor family 31 means single core.

ECC agent fails or hosts don't appear

the hosts don't appear in the EMC Control Center (ECC) master server, or one does but then is replace by another. Sometimes the agent starts, but then unexpectedly quits/dies. If you clone your boxes, exclude /var/ECC or else!

Otherwise just: stop the agent; nuke /var/ECC ; restart agent is the fix for this issue it seems

open a http://powerlink.emc.com account and see the article: "Hostname change not reflected in ControlCenter console." EMC doc ID: emc139067

Looks like you also need to remove a couple more files in /usr/ecc/exec any files with the extensions .lck, .port, .uid and .comfile
