Tonight I need to perform our first failover and giveback since switching from a two node to a four node cluster. Any special considerations, especially as it relates to epsilon and quorum? We are on 8.3.2 P5.
See The Solution
Beforing performing takeover please make sure that you are aware of epsilon.
You can not takover the node which contains epsilon. By using below commands u wll come to know which node is hosting epsilon.
You need to move the epsilon from the node which you are planning to tak over.
Also please take a look at CFO and SFO.
Please make sure that all the aggregates are came back to original node while you are perfroming give back using below command.
storage failover show-giveback
Make sure that you conncted to console or service processor.
