failover-fail back question

Santhosh.c — Wed, 15 Sep 2010 13:34:35 GMT

what will be the status of the SG package after restarting the primary node? Package configured as below.

Package AUTO_RUN is disabled.

Can anybody explain will the package start automatically after the primay node boot completed.
(In my system its not started and I have started the package manually. I want to confirm that whether this is normal or not)

speedy reply is highly appreciated.

Thanks in advance
Santhosh

With AUTO_RUN disabled the package won't start, when you start the cluster.

It needs to be Enabled for that package to start when the cluster starts

But I have one more question. Sorry for not included along with previous one.

I can see in the package.conf file "auto_run yes"

question: Why the auto_run status remain disabled after reboot the server?
Thanks,

The question is, how was the package stopped? If you used cmhlatpkg, that will AUTOMATICALLY disable Global switching (AUTO RUN)
However it will leave the Local Switching (per node as seen by cmviewcl -v) as they were at the time of issuing the command.
When you reboot the primary node, it will continue to run where you started it, but you will have ot manually set AUTO RUN to be enabled using the cmmpdpkg -e command

I can see in the package.conf file "auto_run yes"
That is because the package is configured to autrun when the cluster starts up.

Let me clear my question.

Incident happened:
Server turned off by unknown reason.

Action Taken:
Powered up the server and booted properly

Status of the cluster package:
cmviewcl output was giving package down and auto_run disabled
Action taken: Started the package manually (cmrunpkg)

Checked the package.conf file and found the configuration as "auto_run yes"

I think the senario is clear now and my question also.

Thanks,
Santhosh

"Incident happened:

Please share, when this incident happend whether your package switched to another node?

NO. The package neither switched over to another node nor started on the primary node after it was rebooted.

then given the limited information you have, the package had been started on the node that stayed up, probbly by a manual switch, which would cause the AUTO RUN to show disabled in cmviewcl.
As the cluster was ALREADY running, and you just had the node rejoin it, this does NOT automatically turn the AUO RUN back to enabled, that will ONLY happen when a cmruncl is done after a cluster has been halted.
