Service Group Before After Reboot

[Rajan_Iyer]

Hi,

I have 2 node VCS Cluster. In the same ref. we have scheduled maintenance of hardware. In the same ref we woluld like to do below actions in VCS.

---total 6 Service Groups are running------------------------

We do not want failover while shutting down the servers.

After rebooting we want that only 2 Service Groups will remain online, and remaining 4 will become offline [Also no failover]

Please let me suggest what commands/GUI actions need to be taken before and after reboot.

Note: Meanwhile we do not want failover of any Service Groups.

Please suggest.

Hi Rajan,

If you do an "hastop -all -force" then VCS will stop on all nodes and leave any running service groups online.  With VCS stopped on all node there will be no failover possible.

As for you wanting to start 2 service groups after reboot and the rest stopped, set the AutoStartList of the two service groups that you want started.  With the right settings you can control exactly which nodes the service groups will start on.  Clearing the AutoStartList of the other 4 service groups will prevent them from starting up on reboot.  These changes need to be done prior to stopping the cluster or via offline configuraiton modification methods.

Thanks,

Wally

One more alternative here

-- before rebooting the server, freeze all the service groups persistently ... so no failover will happen..

Once you reboot the server, since all service groups are frozen, nothing will come online ... you can then manually unfreeze the service group which you want to bring online & online those groups..

Hope helps
