Considerations
- bmc/ipmi seems to prefer to be on primary network interface, using a DIFFERENT ip from the actual network
Tools
Scan network for ipmi
http://fish2.com/ipmi/tools/ztools.html or better yet: https://github.com/zenfish/ipmi
HOWTO
ssh shell

Configuring IPMI
IPMI Network configuration
Check ipmi network settings
ipmitool -I open lan print 1
or just
ipmitool lan print 1
Check lan/network configuration
ipmitool -I open lan print
Set network to dhcp
ipmitool lan set 1 ipsrc dhcp
Set network to static
ipmitool lan set 1 ipsrc static
Change ip address
ipmitool lan print 1 ipmitool lan set 1 ipaddr x.x.x.x ipmitool lan set 1 netmask 255.255.255.0 ipmitool lan set 1 defgw ipaddr x.x.x.x
Add vlan ID
ipmitool lan set 1 vlan id 22
Managing users

ipmitool user list 1
Change password
2 is usually ADMIN
ipmitool user set password 2
Show user privilege level
ipmitool channel getaccess 1 3
Reading status
( also see http://sources.redhat.com/cluster/wiki/IPMI_FencingConfig)
Simple status check
ipmitool -I lanplus -H <IPADDR> -U root -P changeme chassis status
Get some hints about commands
ipmitool -I open help
List all sensors
ipmitool -I lanplus -H <IPADDR> -U root -P changeme sdr elist full
or
ipmitool -I lanplus -H <IPADDR> -U root -P changeme sensor
Serial console over LAN
ipmitool -U root -I lanplus -H 10.0.0.91 sol activate
Boot a remote box
ipmitool -U root -I lanplus -H 10.0.0.91 chassis power on
Sensor information
ipmitool -I open sensor
PSU status
ipmitool -I open sdr type "Power Supply" Status
Shut down a remote box
ipmitool -U root -I lanplus -H 10.0.0.91 chassis power off ipmittool -U root -H 10.0.0.91 -E shell
On freeBsd
