  • 1.  Unable to SSH to Node 0 on CLuster SRX4100

    Posted 12-18-2023 20:07

    Hi Team

    I update the core switch EX4600 and after reboot, I got an alert saying that SRX Node 0 is down, I checked the cluster, both nodes are up and running

    I tried to SSH to Node1, it works

    I cannot SSH to Node 0

    This occured right after updating the EX4600 to 21.4R3S5.4

    Please advise

    Hi,

    Which node in the cluster is the active one? 

    show chassis cluster status is the command.  It is possible that during the EX update it caused a failover from node 0 to node 1.  FYI this is an automation thread so was there any automation applied to the upgrade process?

    Hi

    node 0 (primary node) is not accessible using SSH after the switch update

    I can ssh to node 1 (secondary node)

    I can SSH to cluster and I can see both nodes are up

    No automation was applied to the upgrade process

    here  is the cluster status:

    It looks like Node 0 is secondary for Redundancy group 3 what interface do you ssh into?

    Redundancy group: 3 , Failover count: 2
    node0  254      secondary            no      no       None
