Force SRX to boot from Backup image

‎03-11-2014 05:37 AM

If the primary image becomes corrupt after a JunOS upgrade and the SRX100 will not log into cli (mgd not working).

 

/usr/libexec/ld-elf.so.1: Cannot open "/usr/lib/libverify.so.1"

 

Is there a way of forcing the SRX to boot using the backup image?

Do I need to interrupt the boot sequence to do this?

When you connect to the console, is this the output that you see? If it cannot go further then you need a USB with image formatted from another SRX. Reboot with USB installed and it will boot from it. Then you use the snapshot command to install the new image on the primary partition.

If it was at >db, you could enter reset and it heoretically should continue and allow you repair/reinstall image.

What is the SRX version that you are running?

By default, from 10.4 anad above, if primary partition is corrupt, SRX would boot from back-up partition.

If both the partitions are corrupt or compact-flash is faulty, you could end up like the situation that you are surfacing.

 

You could install OS again from loader prompt via USB/TFTP..
