Use ipmitool to remotely control Server
-
Dependence
Assume we need access remote server from local machine, following package and configuration should be matched on them individually.(following command are based on the SuperMicro X10 2U server, Host IP of the two servers are 192.168.1.114 and 192.168.1.115 respectively)
On local machine and remote server: install ipmitool.x86_64
Maybe you can run “yum install ipmitool.x86_64” to install it.
On remote server: we need set BMC LAN IP firstly.
Take remote server 192.168.1.114 for example:
ipmitool LAN set 1 ipaddr 192.168.1.80
Enable BMC LAN access:
ipmitool channel info
ipmitool channel info 1
ipmitool user list 1
ipmitool user enable 3
ipmitool channel setaccess 1 3 callin=on ipmi=on link=on privilege=4
Add BMC user name and password for LAN access:
ipmitool user priv 3 4 1
ipmitool user name 3 admin
ipmitool user set name 3 admin
ipmitool user set password 3 admin
Besides above, remote server's BMC and local machine should connect to same local network, then you can access remote server's BMC through LAN interface. -
Frequent Usage
on local machine to access remote server:
access remote server's console, for example to access 192.168.1.64's console:
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin sol activate
To access 192.168.1.65's console:
ipmitool -I lanplus -H 192.168.1.95 -U admin -P admin sol activate
Control remote server to reset, power down or power cycle:
Take control 192.168.1.64 for example,
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin chassis power reset; # reset 192.168.1.64
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin chassis power on; # power on 192.168.1.64
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin chassis power cycle; # power off 192.168.1.64 for 1s then power it on;
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin chassis power off; # power off 192.168.1.64
ipmitool -I lanplus -H 192.168.1.80 -U admin -P admin sel elist; # get System event log on 192.168.1.64 -
Control remote server from its peer node
Besides the common LAN interface to access remote node, SuperMicro's X10DRS server provides local BMC the ability to access its peer node. Take 192.168.1.64 and its peer node 192.168.1.65 for example, user can tell peer node to reset/power off/power cycle on local node. Following commands are frequently used:
ipmitool raw 0x30 0x70 0x21 0x0 # power reset peer node
ipmitool raw 0x30 0x70 0x21 0x1 # immediately power off peer node
ipmitool raw 0x30 0x70 0x21 0x2 # orderly power off peer node
ipmitool raw 0x30 0x70 0x21 0x3 # power on peer node
ipmitool raw 0x30 0x70 0x21 0x4 # power cycle peer node
