Article ID: KB20673 KB Last Updated: 31 Mar 2011Version: 2.0
Summary:

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

This article is part of the Resolution Guide -- SRX Chassis Cluster (High Availability).

Symptoms:

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


Solution:

Note: This article applies to SRX Series J Series devices running the following versions of Junos:

  • JUNOS 9.4 and above
  • JUNOS with Enhanced Services 8.5 through 9.3


step1  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  
Do you see one node with the status of primary and one node with the status of secondary?

step2  What is the priority of each node?
step3  If the priority for both nodes is between 1 and 254, it means that the Chassis Cluster is in a healthy state.

Each Redundancy Group (other than Redundancy Group 0) contains one or more redundant Ethernet interfaces. A redundant Ethernet interface is a pseudo interface that contains a pair of physical Gigabit Ethernet interfaces or a pair of Fast Ethernet interfaces. If a Redundancy Group is active on node 0, then the child links of all the associated redundant Ethernet interfaces on node 0 are active. If the redundancy group fails over to node 1, then the child links of all redundant Ethernet interfaces on node 1 become active.

Now that you have verified that the Chassis Cluster is in a healthy state, refer to the Understanding Failover section of the Technical Documentation and KB15911 - Troubleshoot High Availability.

For troubleshooting help, refer to Resolution Guide -- SRX Chassis Cluster (High Availability).
