cluster ascii file

[Jeff Disney]

I have done a cmcheckconf on my cluster and have received some errors. I am going to resolve the errors and apply the new configuration, do I have to bring down the cluster to apply the new ascii file?

[melvyn burnard]

that depends entirely on whether you have made any changes to the config, and more imprtantly, what they are.
If you are making no changes, it should apply with the cluster up and running.
Check hte Managing MC/ServiceGuard manual at http://docs.hp.com/hpux/ha for some tables on what can/cannot be changed with the cluster running.

Hi Jeff,

This tells you what you have to do while reconfiguring a running cluster,

http://docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B3936-90053/B3936-90053_top.html&con=/hpux/onlinedocs/B3936-90053/00/00/48-con.html&toc=/hpux/onlinedocs/B3936-90053/00/00/48-toc.html&searchterms=a%7cRunning%7cCluster%7cReconfiguring&queryid=20031027-093822

Hope this helps.

I guess I should have been more specific, I am adding interfaces for failover to the file, in the link to the Serviceguard manual it says you cannot change ip addresses while the cluster is running, I am not changing the address I am just defining the failover interface in the file. I cannot find anything to tell me if I need to stop the cluster to perform this change or not.

You would need to shutdown the cluster in order to add additional Net interface to the cluster. I would expect that you are adding a standby lan interface.

Best way to do is:

# cmgetconf > /etc/cmcluster/cluster.ascii

Edit /etc/cmcluster/cluster.ascii and add your new NIC in there. Remove all the lines starting with Warning from the file.

Check the syntax:

#cmcheckconf -C /etc/cmcluster/cluster.ascii
Then apply conf:
#cmaplyconf -C /etc/cmcluster/cluster.ascii

Thanks,
Pramod

Hi Jeff,

I think you have to shutdown the cluster before you do the change / add more net interfaces for failover.

Hope this helps.
