Junos: SRX Cluster Software Update

Junos: SRX Cluster Software Update

I have had the wonderful joy of performing a SRX software update and it was pretty painless so here is the procedure

  • Run the following command on each of the nodes
    • request system software add no-copy unlink
  • Once the above command has completed on all nodes complete by performing a reboot of the nodes
    • request system reboot
  • Allow the nodes to reboot and you are done!

If you are using the virtual model of the SRX appliance please ensure that you have a snapshot before performing any firmware / software updates

Junos: vSRX Cluster Gremlins

Okay so you can probably tell from the rest of the blog I work with Junos on a regular basis and I have found a bug that has been logged with Juniper that effects there current vSRX releases upto version D60. It would only effect your SRX if you running in chassis cluster mode and what would happen is that it would fail to detect the network interfaces

Anyway Juniper have agreed that it is an issue on there virtual appliance and a work around will be released hopefully the first week of December 2016


Junos: Adding a new node to Chassis Cluster

Junos: Adding a new node to Chassis Cluster

Today I have been playing with the vSRX range from juniper and I had broken one of the nodes and instead of repairing the VM it was much easier to re-provision the vSRX VM and add it back into the configured cluster

So First of all spin up a new vSRX VM and run the following

# Enter Configuration Mode
# Goto Top of Configuration File
# Delete Entire Configuration
# Add root password on the appliance
set system root-authentication plain-text-password
# Save empty configuration
# Exit to operational mode
# Join node to cluster
set chassis cluster cluster-id <0-255> node <0-1>
# Perform Node Reboot
Request System Reboot


Once the node has rebooted check the cluster status by running the following command

show chassis cluster status
