I attempted to upgrade a SRX210H from 9.5 to 10.3. From the web interface everything seemed to go well but when the box rebooted I ended up at the U-Boot prompt (1.1.6-JNPER-1.9). I've searched for the error to no avail. I've found all sorts of information on using loader (which I don't have and seem to not be able to get). Anyone with any ideas on how I can recover?
If you check the release-notes, you'll see there's always a paragraph which details a restriction of how many versions apart you can do an upgrade. You went too far. The supported upgrade limit is 3 major releases (so 10.1 should have been your target, then once that's complete 10.3 would have been OK). You can occasionally, by accident, get away with violating this rule, but that's the envelope within which we test and the only thing supported.
Hopefully you did "request system snapshot" (try that ScreenOS!) for a backup you should be able to easily recover.
No such luck. It was a fresh config and I decided to start by upgrading before doing anything else. I was actually trusting the little note on the side of the software page which seem to imply that it was okay to upgrade from 9.0 or later firmware. Well I'll have to read everything before proceeding next time.
Any idea how I get my hands on a u-boot image with laoder and what the u-boot commands (address) are so I can get to loader so I can then do a tftpboot? I tried to access JTAC but was denied. I've also sent an email to our Juniper rep to see how we go about getting support.
