Linux Hints, Top Tips, and FAQs
Here are some of the Linux hints and documentation that seems to be woefully lacking or just mis-leading on the greater wider Internet.
Setting iDRAC8 Server info
This applies to Dell servers of course. First off, install ipmitools
:
apt-get update; apt-get install ipmitools
To find out the options available in ipmitools
, run:
ipmitools help
and there is a manpage available too.
To set the iDRAC8 System Host Name, you want:
ipmitools mc setsysinfo system_name HOSTNAME
To set the iDRAC8 Operating System, you want:
ipmitools mc setsysinfo os_name OSNAME
To set the iDRAC8 Operating System Version, you want:
ipmitools mc setsysinfo delloem_os_version OSVERSION
And that's it - after that, if you refresh the iDRAC8 Server Overview screen you will see the changes you made.
