Freeze SG or Freeze Node ?
I have a scnario where applications are under cluster [2 node cluster]. I had an issue in the past where hastop -local was executed before bringing down applications manually which resulted in appsg to go in faulted state.
My question is should I freeze the service groups individually or should I freeze the nodes while performing OS patch maintainance ? Does freezing node solves the same purpose as that freezing sg's in a perticular node ?
