IPMI

IPMI - Intelligent Platform Management Interface

Working with IPMI

Einstein , Pumpkin , and Taro have IPMI cards installed. These cards are accessible from the Farm subnet. Their addresses are:

Einstein: 10.0.0.148 Pumpkin: 10.0.0.143 Taro 10.0.0.147

You will need to use the ADMIN user account with the system's root password to access the IPMI devices.

There are several tools available for working with IPMI. You can use the ipmitool and ipmiconsole utilities from the Linux command line from Einstein, Taro, and Pumpkin. They are installed via the yum repos as components of the freeipmi package.

ipmitool is a Linux command-line tool for sending control messages to remote IPMI devices. This can be used for checking sensor readouts and for sending remote power on/off messages.

ipmiconsole is Linux command-line tool for opening a Serial-over-LAN connection to remote IPMI devices.

Taro

Taro has a SuperMicro IPMI card installed: LAN: 10.0.0.147
Login as ADMIN with root password.

Initial configuration was through the BIOS (under Advanced). Here you can set the IP address. After that you can manage the card over the LAN interface, either from a web browser, or by using the SuperMicro IPMI control software (over LAN) is installed in /opt/SUPERMICRO/IPMIView/. This control software has a few more options than the web interface.

Setup of system

Basically, I just plugged in the card, then set the IP number.

Finally in Taro, you need to add a line for the serial console to work. In inittab add the lines:

#
# Run a console on the serial line to the IMPI card
#
T1:2345:respawn:/sbin/mgetty -r -s 19200 ttyS1 
#

And for GRUB you want to add:

...... console=tty0 console=ttyS1,19200n8r
