How to do troubleshoot to a Chassis Cluster showing as Primary/Secondary but still not acting as a healthy cluster.

The goal of this article is to verify that a Chassis Cluster in a Primary/Secondary state has the proper priority. 

  Run the command show chassis cluster status on either node to verify the Chassis Cluster status:

{primary:node0}
root@J-SRX> show chassis cluster status 
Cluster ID: 1 
Node                  Priority          Status    Preempt  Manual failover

Redundancy group: 0 , Failover count: 1
    node0                   100         secondary      no       no  
    node1                   150         primary        no       no  

Redundancy group: 1 , Failover count: 1
    node0                   100         secondary      no       no  
    node1                   150         primary        no       no  

• Yes - Proceed with Step 2
• No    - Go to KB20641 - Troubleshooting steps when the Chassis Cluster does not come up [juniper.net]

• If the priority is 0 , then proceed to KB16869 - What does priority 0 mean in a JSRP chassis cluster? [juniper.net]
• If the priority is 255 , then proceed to KB16870 - What does priority 255 mean in a JSRP chassis cluster? [juniper.net]
• If the priority is between 1 and 254 , proceed to Step 3.
