[j-nsp] snapshot partition

[Onam Rubio]

Hello experts,

I need to replace the Compact Flash(CF) of my Juniper M10 but when I do the "request system snapshot partition" the router can't boot the junos.

Step 1:
onam at M10# run request system snapshot

Step 2:
onam at M10# run request system power-off media disk

Step 3:
I replace the CF and ran the command onam at M10# run request system snapshot partition

After I ran this command the router start the snapshot partition then reboot and can't find the operating system.

**I receive the follogin message**

onam at M10# run request system snapshot partition
