Perform the following procedure:
show chassis hardware
.Check the Junos OS version on the active node of the cluster and upgrade or downgrade Junos (for more information, refer to KB16652 - SRX Getting Started - Junos Software Installation/Upgrade ) on the new device, so that they match.
Save the configuration in a file on the working node and upload the file to the new device in the /var/tmp
directory.
Get into configuration mode.
Execute the # delete
command.
# set system root-authentication plain-text-password
# commit
show chassis cluster status
command on the working node to identify the cluster-id):code> set chassis cluster cluster-id <id> node <No.>
<No.>
will be 1 or 0, depending on which node is being replaced.> request system reboot
/var/tmp
directory in Step 1. Use the following command to load the configuration:# load override /var/tmp/ <filename>
# commit and-quit
> request system halt
Check the status of the FPC PIC by executing the show chassis fpc pic-status
command. In the output, all of the FPCs and PICs should be online.
When the new node comes online, it should join the cluster as the secondary. You can check the status by executing the show chassis cluster status
command. In the output, the priority of RG0
should be the configured value, and the priority of the other RG should be 0
if interface monitoring has been configured.
As the new node comes online, it will transition through the following states: Hold > Primary > Secondary. If the new node does not complete the move to Secondary state, contact Juniper Technical Assistance to investigate.
If the output that is generated in Step 10 shows the primary and secondary for all RGs, then connect all the revenue port cables and again check the chassis cluster status via the show chassis cluster status
command. In this output, you should see the configured values for all of the RGs.
