To upgrade SG to A.11.18 ( four node Metro cluster)
I have scenario for four node in which i have to configure Metro Cluster.
I have already setup DR site with latest SG-A.11.18 and created local cluster.
In Primary site (which is production) Only serviceguard extension for rac is installed and i have to install Service guard A.11.18 for Metro & serviceguard extension for rac to latest version addition to this i have to re-organize the filesystem.
Now the issue is, Its very critical system (Primary site). Its very hard to get downtime for long hours ( To upgrade both nodes to Latest Sg & patches ..etc).
What will be the best way to perform the upgrade with minimul down time.
Your Reply to this issue will be appreciated.
Thanks & Regards
Ali...

Re: To upgrade SG to A.11.18 ( four node Metro cluster)
Once you have this up and running, you can then remove another node and add it to the new cluster and so on.
Doing these one at a time, gives you better control and allows for more options with scheduling downtime. It also divides the workload in case you run into an issue, since you will have fewer boxes/packages to look at for each phase.
Just a thought,
Rita

Re: To upgrade SG to A.11.18 ( four node Metro cluster)
Thanks for quick response
but the issue is i have to go with management too. It will be good if i take both the servers at a time and Install & upgrade but what if any thing goes wrong when upgrading both the servers & configuring METRO cluster, then i have to add the time for revert back to orginal state too.
IF you have any idea to do the upgrade in minimul downtime, pls confirm.
Thanks.....
Regards

Re: To upgrade SG to A.11.18 ( four node Metro cluster)
One more thing, how it is possible DR- with 2 nodes & primary with 1 node MC/SG and again how i will add 2nd Node after upgrade & patches in MC/SG.
There is note in Metro-Rac docs online deletion & adding required same amount of nodes on both sites.
Pls confirm..
Thanks
