Configuring the CompactFlash Card on an M10i Routing Engine

After installing the CompactFlash card for the first time, you must copy the software from the Routing Engine's hard disk to the CompactFlash card.

To copy software to the CompactFlash card, perform the following procedure:

1. Install the CompactFlash card and replace the Routing Engine as described in Configuring the CompactFlash Card on an M10i Routing Engine and Installing the M10i Routing Engine.
2. Log into the UNIX shell on your router, and change to the /var/tmp directory.
3. Format the internal CompactFlash card using the following commands:
   
   

   dd if=/dev/zero of=dev/ad0 count20
4. On the console or other management device connected to the Routing Engine, enter CLI operational mode and issue the following command to copy the currently running and active file system partitions on the router to standby partitions on the CompactFlash card.
   
   

   user@host> request system snapshot partition

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

   For more information about the command, see the Junos System Basics and Services Command Reference.

5. Issue the following command to reboot the router's software:
   
   

   user@host> request system reboot

   The CompactFlash card will now be the primary boot device.

6. You can verify correct boot order by issuing the show system boot-messages command. The output lists the devices mounted. The CompactFlash card is located at ad0.

   For more information about the command, see the Junos System Basics and Services Command Reference.
