Applying SQL 2012 Service pack 3 in Active\Passive cluster

  • I need to apply Service Pack 3 in SQL 2012\Windows 2012 R2 server. Its Active\Passive node. Do I need to remove the passive node from the "Possible Owner" before applying Service pack? All I know is its not needed since the Windows 2012 R2 Failover cluster will be aware SP3 is being applied to the passive node and it will not initiate a failover to the passive node rather it will remains in Active node incase of any issue. Could some one clarify please...

  • In a 2 node cluster you could get by most likely, I have done this without issue before. But why wouldn't you take the 20 seconds to eliminate the possibility of something going wrong?

    You remove the node as a possible owner from the networkname resource only and then add it back again once the SP has been completed.

    WSFC subsystem checks the networkname for a sql server cluster role to determine the possible failover nodes
