Problem :- RE0 stuck in the # prompt while performing the Junos upgrade from 13.2 to 13.3 and you want to fix the issue in the respective RE.
1. We found the RE0 trying to boot with the compact flash as primary and disk 1 as the next bootable device; however, it is continuously stuck in the # prompt mode.
2. We made the disk 2 as a next bootable device and tried to reload; however, it still stuck in the # prompt mode.
3. We downloaded the 13.3 install media to made the USB as an emergency bootable media and recovered the RE0 from the booting issue.
4. We performed the “request system screenshot” and made the compact flash to boot with the proper Junos image.
5. We transferred the Junos 13.3 from RE1 to RE0 to upgrade it.
6. We deactivated the commit sync under system and graceful restart under routing-option configuration; however, we found the GRES is not configure under chassis redundancy.
7. We successfully upgrade the Junos 13.3 in the RE0 and reverted the configuration with the GRES and made mastership toggle from RE1 to RE0.
Suggestion:
1. Please deactivate the GRES, NSR/Graceful restart and commit sync before performing the Junos upgrade/downgrade in the dual routing engine platforms.
2. Please perform the “request system snapshot” on both the routing engine before executing the Junos upgrade/downgrade.
