I've always like to set my Dell iDrac network management ip to a private one as compared to a public ones. However, when a dell server is causing a problem, i might not be able to access the server web interface since its an internal ip and the server might not be able to connect directly via ssh. In this case, how do i reboot the server without calling help from the datacenter? Apparently, there is a tool call racadm which can be used to assist such incident.
If you have access to the other network servers where you can still ping the dell iDrac private ip, you can fire the following commands to ensure that your server will reboot itself.
racadm -u ADMIN -p ADMIN -r 192.168.0.123 serveraction hardreset
In the above, case, i am connect to the idrac 192.168.0.123 and login with the ADMIN and password ADMIN to do a 'serveraction' with a hardreset. You can specifies the action. The options for the string are:
- powerdown – Powers down the server module.
- powerup – Powers up the server module.
- powercycle – Issues a power-cycle to the server module.
- hardreset – Issues a hard reset to the server module.
But do remember to install OpenManage or racadm on your server or else you are on your own! For more options available using racadm visit their doc page.
