Configure BMC on each node for remote control using LAN for IPMI-based node fencing to function properly.
You can configure BMC from the BIOS prompt, using a distribution-specific management utility, or you can configure BMC using publicly available utilities, such as the following:
IPMItool, which is available for Linux:
IPMIutil, which is available for Linux and Windows:
When you configure the BMC on each node, you must complete the following:
- Enable IPMI over LAN, so that the BMC can be controlled over the management network.
- Enable dynamic IP addressing using DHCP or GNS, or configure a static IP address for the BMC.
- Establish an administrator user account and password for the BMC.
- Configure the BMC for VLAN tags, if you will use the BMC on a tagged VLAN.
The configuration tool you use does not matter, but these conditions must be met for the BMC to function properly.
