OpenHPC:IPMI StaticIP

Configure Static IPMI IP address using the cluster IP as a basis

Assuming you have all your nodes setup on 10.10.0.0/24 and want to configure IPMI with an equivalent static IP in 10.11.0.0/24 and you have ipmitool and pdsh installed:

pdsh compute[01-79],infra[01-14] 'ipmitool lan set 1 ipsrc static; octets=$(ip a | grep "10.10." | sed -rn "s/.+\.([0-9]+\.[0-9]+)\/24.+/\1/gp"); ipmitool lan set 1 ipaddr 10.11.$octets; ipmitool lan set 1 netmask 255.255.0.0; ipmitool lan set 1 defgw ipaddr 10.10.10.1' | dshbak

...

Setting LAN IP Address to 10.11.0.23
Setting LAN Subnet Mask to 255.255.0.0
Setting LAN Default Gateway IP to 10.10.10.1

infra14
----------------
Setting LAN IP Address to 10.11.0.24
Setting LAN Subnet Mask to 255.255.0.0
Setting LAN Default Gateway IP to 10.10.10.1

this expands up to run the following 3 commands on every node: ipmitool lan set 1 ipsrc static ipmitool lan set 1 ipaddr 10.11.0.103 ipmitool lan set 1 netmask 255.255.0.0 ipmitool lan set 1 defgw ipaddr 10.10.10.1

to adapt make sure that you match the appropriate section of the

ip a

command e.g.:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

   link/ether ac:1f:6b:b2:9f:06 brd ff:ff:ff:ff:ff:ff
   inet 10.10.0.103/24 brd 10.10.10.255 scope global eth0
      valid_lft forever preferred_lft forever
   inet6 fe80::ae1f:6bff:feb2:9f06/64 scope link 
      valid_lft forever preferred_lft forever

the command grabs the inet 10.10.0.103/24 section of the above and would work perfectly with a /16 segment too

changing SMC server IPMI shared state

To get LAN mode:

ipmitool raw 0x30 0x70 0x0c 0.

To set LAN mode dedicated:

ipmitool raw 0x30 0x70 0x0c 1 0.

To set LAN mode onboard/shared:

ipmitool raw 0x30 0x70 0x0c 1 1.

To set LAN mode failover:

ipmitool raw 0x30 0x70 0x0c 1 2.
