Replacing a CompactFlash Card in an SRX5K-RE-1800X4 Routing Engine

Switching from the Master Routing Engine to a Backup Routing Engine

On services gateways with two Routing Engines, one Routing Engine is the master and the other is backup. By default, the Routing Engine on the host subsystem is the master.

If you are removing CompactFlash Card on the master Routing Engine, you can switch mastership so that routing is not disturbed.

1. Enter CLI operational mode, and issue the following command to copy the currently running and active file system partitions on the SSD, to the standby partitions on the internal compact flash card.
   user@host> request system snapshot

   Wait until a message appears on the console confirming that the procedure is complete.

2. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
   • Check the MASTER LED on the Control Board. If the blue MASTER LED is lit, the host subsystem is functioning as the master.
   • Enter the following CLI command. The master Routing Engine is designated Master in the Current state field:
     user@host> show chassis routing-engine

     Routing Engine status:   
       Slot 0:
         Current state                 Master
     ...
      

3. If the host subsystem is functioning as the master, switch it to be the backup by using the request chassis routing-engine master switch command.
4. From the master Routing Engine, issue the request system power-off other-routing-engine command to power off the backup Routing Engine.

   Wait until a message appears on the console confirming that the procedure is complete.

5. Verify that the ONLINE LEDs on the backup Routing Engine faceplate are off.

Copying Junos OS to the CompactFlash Card in an SRX5K-RE-1800X4 Routing Engine

1. On the console or other management device connected to the Routing Engine, boot from the SSD.
2. Start the CLI, and enter the command request system snapshot partition to copy the currently running and active file system partitions on the SSD to the standby partitions on the CompactFlash card.
3. Wait until a message appears on the console confirming that the procedure is complete.
4. Enter the command request system reboot to reboot the Routing Engine.

   The CompactFlash card will now be the primary boot device.

5. Enter the command show system boot-messages to verify the correct boot order. The output lists the devices mounted.
