IPMI
IPMI allows us to access a physical server removetly, as if we were in the colo with a monitor and keyboard plugged in. At least in theory. We used to use a simple serial cable to achieve this feat. However, new servers are no longer beings shipped with serial ports and motherboard/bios software no longer support them. Instead, we are expected to use IPMI.
IPMI provides a million ways to connect, but we are enabling two. Both are configured to use a local, non-routable IP address.
- web-based access (we will setup nginx to proxy from a public address to the non-routable address)
- serial over LAN access, using ipmiutil which will be run from a server in the cabinet
Unfortunately, IPMI is complex and varies considerably from computer to computer. Here are the steps used to connect john.
BIOS/Setup
When you first boot the computer, IPMI has to be enabled and assigned an IP address.
We use a non-routable IP address so the only way to connect to IPMI is via a machine in the colo itself.
Below are the screen shots of the bios and their settings.
