We have an Active-Passive SQL Server 2008 Failover Cluster installed. Front end is sharepoint.
They have two instances on each cluster, one instance is named prod_mssqlserver, the other is for qa_mssqlserver.
Now I need to apply service pack3 on it.
Do I have to run it on both physical servers? And does each run will do the SP for both instances?
We can take down both nodes for patch, do not need to do the failover for this purpose, shall I run the passive nodes first without taking down the active one?
Then I can take down the active one to do the patch. I mean I can take down either of them to do the patch without needing to do fail over, how can I do that?
Thanks, |
