Too many power outages in Baker Lab!

Reboot switches

• 8 switches support the clusters (out of 12 in the room).

Start headnodes, if not on already

• Only a few are on UPS. Those can obviously be left on.
• None should be set to auto-start on power-off.

Confirm headnodes accessible via SSH

PuTTY on Windows

Use FMPro to get connection info?! (not the right info there, though...)

Menu => List Machine / User Selections = > List Group or selected criteria

• Machine function => Server HN

Start compute nodes

If nodes done show up, consider:

• Restart Torque scheduler on problematic nodes.
• Try rebooting the switch the affected nodes are connected to, especially if the problematic nodes are grouped to a single switch.
• Hook up a monitor as one of the high nodes boot.
