PowerHA 6.1 question

[fbergenh]

One of our customers has just set up a new PowerHA 6.1 cluster with two nodes and I am just checking these nodes.

I stumbled upon something that isn't correctly configured but I am not sure it will cause any trouble in the near future. Maybe someone here can tell me that.

During installation there were two groups created, hacmp and haemrm. According to a redbook, these groups should have the same group-id, but in this case something went wrong.

on node 1 hacmp has group-id 205 and on the other node hacmp has group-id 204.
on node 1 haemrm has group-id 202 and on the secondairy node haemrm has group-id 207.

Will this cause any problems?

I would be very surprised to hear the synchronization is successful. Only seen things like this when configuration was performed from separate nodes with no synchronization in between.

I would do a snapshot on one node, and read the ODM at this point. and/or a snapshot on both and use diff -b to compare the snapshots. Previously the id number was a unique item.

Gut feeling: not desirable.

Hi Michael,

Do you know of a way to solve this?

Maybe bring down the cluster, change the group-id's so that they are the same on both nodes and start the cluster again?

Maybe remove both groups from the cluster config?
