Summary:
What does priority 0 mean in a JSRP chassis cluster?
Symptoms:
The show chassis cluster status command shows priority as 0 for a redundancy group.
{primary:node0}
root@SRX> show chassis cluster status 
Cluster ID: 3 
Node                  Priority          Status    Preempt  Manual failover

Redundancy group: 0 , Failover count: 1
    node0                   129         primary        no       no  
    node1                   128         secondary      no       no  

Redundancy group: 1 , Failover count: 3
    node0                   0           primary        no       no  
    node1                   0           secondary      no       no  
Solution:
Priority 0 means that the node is in the ineligible state. There are several reasons why you could see the ineligible state:
  • Cold sync failure
  • Monitored interface down
  • IP Tracking is failing (SRX3000 and SRX5000)
  • Possible hardware issue

Perform the following to correct the priority 0 state:
  • Check chassis cluster statistics. Are there any missing heartbeats or probes?
  • Check chassis cluster interfaces. Are any of the monitored interfaces down or is a tracked IP missed?
  • Check jsrpd logs. Are there any errors?
  • Check chassisd logs.  Is any hardware down?
  • Check messages log. Are there any events leading up to the problem?
