Linux's "eth0" is the physical "Port B" (I put a sticker over it marked eth0). "eth1" is "Port A". Just keep this in mind.

Both disks have a small partition (part1) and a big partition (part3). The big partitions are RAID1'ed together; the small partition on the first drive is boot, the second drive is swap.

1. Console

Mire's ttyS0 is connected to krunk's LOM port.

To access Krunk's console, log in to mire and type

sudo cu -s 9600 -l /dev/ttyS0

This will give you access to Krunk's console. We have told Krunk not to respond to BREAK signals on the serial line (echo 0 > /proc/sys/kernel/stop-a), so in order to get its attention when it is stuck you must use the LOM attention sequence #. (return, hash mark, period). This will give you the lom> prompt; type console to go back to Krunk's console.

To exit cu, type ~. (return, tilde, period, return). You might need two tildes if you're on an SSH connection to Mire (and not Mire's console).

2. LOM

If the system is in a bad state and the console is unresponsive, you need to use LOM to powercycle the machine.

Enter the LOM prompt (#.), then type the desired command. I used poweroff and then poweron (Note that after each command, the prompt will return quickly, but any messages may be printed to the console later, asynchronously. For example, the poweroff command will result in the poweroff message being printed to the screen a couple seconds after the prompt has already returned, so be patient).

In any case, on reboot, the machine will show prompt "ok".

At the prompt, it is necessary to type in "boot" and subsequently press Enter key twice for the machine to boot our OS.
