Any idea on how to recover a Catalyst9300 from ROMMON

[gnijs]

It boots into ROMMON (after platform install software xxx)

i guess flash is corrupt

switch: dir flash:

I tried this and it will run or a few minutes and then stop and then the switch will reboot. Funny thing I noticed, I have tried 3 different USB drives and the process runs longer on 1 of the 3 USB flash drives , but they all do stop and the switch reboots. Prior to using them for the switch I formatted them using Fat32. I have tried using FAT and NTFS and the drive will not seen rom the switch.

Found the issue: 

set MANUAL_BOOT=no
set SWITCH_IGNORE_STARTUP_CFG=0

[nicholaswojciechowski]

I added the commands above and it still does not work. I am out of ideas how to fix this. I do not understand why I cannot access flash:

switch: dir flash:
media drive flash: not present.

Send the complete output to the command "set".

Contact Cisco TAC and get the switch RMA-ed.

Bumped into this issue this morning after a member of a stack failed its upgrade. Realised after a while it was because the switch still had data stack cable attached to it. Once the switch was fully isolated the switch upgraded and booted after restart. One to watch out for.

[ayoubyousif2021]

thank you very much. it worked for me on C3900

[chariths]

this was very helpful.

emergency-install usbflash0:IOS_filename.bin 

this command solved my problem. thanks 

[nicholaswojciechowski]

I was able to get the switch RMA'd. Thanks to all that replied and tried to assist me with this issue.

I believe that you didn't use the right command, do the following:

unset set DEFAULT_ROUTER

set DEFAULT_GATEWAY 10.96.56.17

wish that will help
