Requirements for Enabling IPMI
You must have the following hardware and software configured to enable cluster nodes to be managed with IPMI:
-
Each cluster member node requires a Baseboard Management Controller (BMC) running firmware compatible with IPMI version 1.5 or greater, which supports IPMI over LANs, and configured for remote control using LAN.
-
The cluster requires a management network for IPMI. This can be a shared network, but Oracle recommends that you configure a dedicated network.
-
Each cluster member node's port used by BMC must be connected to the IPMI management network.
-
Each cluster member must be connected to the management network.
-
Some server platforms put their network interfaces into a power saving mode when they are powered off. In this case, they may operate only at a lower link speed (for example, 100 MB, instead of 1 GB). For these platforms, the network switch port to which the BMC is connected must be able to auto-negotiate down to the lower speed, or IPMI does not function properly.
-
Install and configure IPMI firmware patches.
Note:
IPMI operates on the physical hardware platform through the network interface of the baseboard management controller (BMC). Depending on your system configuration, an IPMI-initiated restart of a server can affect all virtual environments hosted on the server. Contact your hardware and OS vendor for more information.
