    Hi Allaboutunix,

     

    If I/O fencing is not enabled, and system enters in jeopardy state, then ServiceGroups are auto-disabled on that system. Thus, ServiceGroups will not online/failover/switchover on/from that particular system. This is irrespective of whether SGs has critical resources or not.

    If I/O fencing is enabled, no impact on SGs if system enters in jeopardy state.

    System enters jeopardy state when only last link is left active. Restore other links and system will recover from jeopardy.

     

    Thanks & Regards,
