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
