Using DRAC as fence device for RedHat cluster

By
fence_drac is an I/O Fencing agent which can be used with the Dell Remote Access Card (DRAC). This card provides remote access to controling power to a server. It logs into the DRAC through the telnet interface of the card. By default, the telnet interface is not enabled. To enable the interface, you will need to use the racadm command in the racser-devel rpm available from Dell. To enable telnet on the DRAC:

[root]# racadm config -g cfgSerial -o cfgSerialTelnetEnable 1

[root]# racadm

racreset

fence_drac accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_drac can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
