Debian : mise en place d'IPMI
Boris HUISGEN
|
Voici les étapes nécessaires à une mise en place rapide d’IPMI sur un système Debian.
root@srv01:~# apt-get install ipmitool
root@srv01:~# lsmod | grep ipmi
Si les modules IPMI ne sont pas chargés, il faut le faire manuellement :
root@srv01:~# modprobe ipmi_si ipmi_devintf
Si le message d’erreur _Error inserting ipmisi: no such device survient, la carte réseau est tout simplement incompatible avec IPMI. Sinon, on peut remonter des infos pertinentes :
root@srv01:~# ipmitool chassis status

Une adresse IP peut en plus être attribue à la carte réseau pour permettre un management distant :
root@srv01:~# ipmitool lan set 1 ipaddr 172.16.0.1
root@srv01:~# ipmitool lan set 1 netmask 255.255.0.0
root@srv01:~# ipmitool lan set 1 defgw ipaddr 172.16.0.254
root@srv01:~# ipmitool lan set 1 access on
root@srv01:~# ipmitool user list
root@srv01:~# ipmitool user set password 2 secretpasswd
Depuis un autre poste , un reboot hard est possible par ces commandes :
manager@client:~$ ipmitool -H 172.16.0.1 -U root -P secretpasswd power off
manager@client:~$ ipmitool -H 172.16.0.1 -U root -P secretpasswd power on
