The bottom processor is not working, and you do not have an active database on the top processor.

Hard to tell what’s gone wrong here but I would be trying reloading each processor individually, I’d have a monitor attached to bottom processor to look for boot messages (cannot tell if Linux is dead or just openais service) and if I had backup discs or a RISO image I’d be looking for them.
 
One processor linux is booting up as per the images below

OK but we knew that one was booting. What about the other one.

You can push the button to the right of the OLED to show the processor status, you need to see an A, but you don't have one as you you can see the same thing in the web GUI, your database has not loaded.

So you will probably be lookung at restoring backups, unless your other processor boots.

If Assistant is running, it might be worth checking Backup Restore for any backups saved to HD, Buffer or SFTP server, and letting it make a restore, and also in Configuration Management under HIM, maybe you have an RMX backup (regen). That's harder to restore though.
