If you forgot what iLO IP has been defined on your linux server and you are working remotely on it, don’t worry, you can still retrieve it with a common tool called ipmitool – available on most of the distros with standard packages:
[admin@myserver /]# ipmitool lan print Set in Progress : Set Complete Auth Type Support : Auth Type Enable : Callback : : User : : Operator : : Admin : : OEM : IP Address Source : Static Address IP Address : 10.10.50.20 Subnet Mask : 255.255.255.0 MAC Address : 1a:2b:3c:4d:56:78 SNMP Community String : BMC ARP Control : ARP Responses Enabled, Gratuitous ARP Disabled Default Gateway IP : 10.10.50.254 802.1q VLAN ID : Disabled 802.1q VLAN Priority : 0 RMCP+ Cipher Suites : 0,1,2,3 Cipher Suite Priv Max : XuuaXXXXXXXXXXX : X=Cipher Suite Unused : c=CALLBACK : u=USER : o=OPERATOR : a=ADMIN : O=OEM
If you’re getting such an error when you are using the command:
[admin@myserver /]# ipmitool lan print Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
This means you just need to enable some modules before:
[admin@myserver /]# modprobe ipmi_devintf [admin@myserver /]# modprobe ipmi_si
