I rebooted my SRX 380 running on Junos 19.3R2-S3.4 and it seems to be stuck in the following reboot loop because of an in progress coredump. How can I get out of this and force the box to start up ? Also, how can I prevent this from happening again ?
root@srx380> request system reboot Reboot the system ? [yes,no] (no) yes
Shutdown NOW! [pid 5800]

This goes on and on, and the box never actually reboots.
If the device says that "Coredump of a process in progress" but actually if it can't core-dump then it can be a critical issue with the hardware itself and mostly it will throw an error - e.g. ** Dump failed (rc = 5) **. If that's the case then most probably RMA might be required.
However, it would be better if we can carry out the recovery steps as suggested by others.
If the above step doesn't work, then we can try one more recovery method. For this one, you need the working SRX380 available. We will be taking the snapshot of the device from the working SRX via USB and insert the USB in non-working SRX and try to boot it from USB - https://kb.juniper.net/InfoCenter/index?page=content&id=KB29811
If above even doesn't work and if the device stuck in DB> prompt, you give the following commands to recover it. i.e. db> cont and if it doesn't work then db> reset.
If none of the above works, then RMA is the only option.
Note: While performing step 1, it would be great if you can download and install recommended Junos version - Junos 20.1R1-S2 if the device is deployed in standalone. Because when the device was launched it came with Junos 20.1R1 by default I believe.
Thanks, π00bm@$t€®. Please, Mark My Solution Accepted if it Helped, Kudos are Appreciated too!!!
Please be aware that SRX380 requires at least Junos 20.1R1 or newer to operate. Having it boot on 19.3R2-S3 actually impresses me a bit
I expect your coredump loop will be solved upgrading to 20.1 or 20.2 based releases. It can be that you have to do a USB based installed as previously mentioned as I would not trust an upgrade from 19.3R2 to be working on a non-supported platform for that release.
