Lights Out Management

The BMC card has a dedicated RJ45 socket on the motherboard which can be used independently from the main NICs.

Common actions (easy way)

RobH has written us a wrapper around the common ipmitool commands. It exists on sockpuppet.

root@sockpuppet:~# ipmi_mgmt
Syntax is ipmi_mgmt <host> <commands>
Command Listing
Power commands: powercycle, powerdown, powerup, powerstatus, powermonitor
Setting one time boot option: bootbios, bootcdrom, bootdisk, bootfloppy, bootpxe
Serial Console: console & ~~. to disconnect when done; consoleclose (for unintentional DC that doesn't free the com port)
BMC/LOM specific: bmcinfo, bmcreset.
Info gathering: fru, id (flash lights on system for local tech ID), log (BMC event log), sdr, sensor, sysinfo
