How to enable a serial console with IPMI

A serial console will allow you to send all text based output to one of the on-board serial ports. While this can be done using a physical serial port and an external terminal server, it’s more likely that Serial Over Lan (SOL) is used.

How to expand an existing LSI raid array using MegaCli

Warning: You should ALWAYS make a backup of all of your information on the raid array before performing any of these steps.

How to update the date/time on LSI Raid cards using MegaCli

Setting the date/time on your controller is advised to keep system logs in sync. Although this is normally done by the drivers after bootup, we can do this manually with the MegaCli tool using the following syntax: MegaCli64 -AdpSetTime yyyymmdd hh:mm:ss -a<adapter#> yyyy is year in 4 digit format: 2013 mm is month in 2 […]

Creating Groups of Nodes in TORQUE

Despite being a simple first in/first out (FIFO) scheduler, pbs_sched can use node properties to emulate host groups. This can be useful if you have different types of nodes that provide different types of resources. The nodes available in TORQUE are controlled by the file /var/spool/torque/server_priv/nodes. The most basic configuration simply lists the nodes and […]
