Re: how to reinstall junos

It may be simple power outage that forces Junos boot from the backup partition.
Issue the
show system snapshot media internal

 

If primary partition shows normal version – simply reboot the device. It will boot from primary.

Re: how to reinstall junos

Hi Rohit,

 

It looks like the device is not able to load the junos from primary media. Once the srx boots us from secondary partition you can issue command > request system snapshot media internal slice alternate

This will copy the image of the secondary media to the primary media and the next time you boot the srx it should load from the primary media.

 

Hope this helps.
