Based on my notes, here's how I configured the DRAC interface on a Dell 1950
for use as a fence device:

	Configuring the card from Linux depending on the installation of Dell's
	OMSA package. Once that's installed, use the following 
commands:

		racadm config -g cfgSerial -o cfgSerialTelnetEnable 1
		racadm config -g cfgLanNetworking -o cfgDNSRacName HOSTNAME_FOR_INTERFACE
		racadm config -g cfgDNSDomainName DOMAINNAME_FOR_INTERFACE
		racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i 2 PASSWORD
		racadm config -g cfgNicEnable 1
		racadm config -g cfgNicIpAddress WWW.XXX.YYY.ZZZ
		racadm config -g cfgNicNetmask WWW.XXX.YYY.ZZZ
		racadm config -g cfgNicGateway WWW.XXX.YYY.ZZZ
		racadm config -g cfgNicUseDhcp 0


	I also save a backup of the configuration with:

		racadm getconfig -f ~/drac_config


Hope this helps,

Mark
