Upgrade HP iLO via SSH
I recently had a situation where an HP Proliant server’s ILO web interface would not load. Assuming a potential firmware bug, I decided to update the firmware – usually done through the web console. Thankfully, it is an easy process.
1.) Download the iLO firmware(a .bin file) from HP’s site for your specific Proliant Generation and place it on an available web server(IIS, etc.).
2.) Login to your iLO via SSH (Using Putty, etc.)
Wait for 30-45sec for iLO to update and restart and you should be all back up and running.
