Intelligent Platform Management Interface (IPMI) provides a set of common interfaces to computer hardware and firmware that system administrators can use to monitor system health and manage the system.

Oracle Clusterware can integrate IPMI to provide failure isolation support and to ensure cluster integrity. You can configure node-termination with IPMI during installation by selecting IPMI from the Failure Isolation Support screen. You can also configure IPMI after installation with crsctl commands.

• Requirements for Enabling IPMI
  You must have the following hardware and software configured to enable cluster nodes to be managed with IPMI:
• Configuring the IPMI Management Network
  You can configure the BMC for DHCP, or for static IP addresses. Oracle recommends that you configure the BMC for dynamic IP address assignment using DHCP. To use this option, you must have a DHCP server configured to assign the BMC IP addresses.
• Configuring the BMC
  On each node, complete the following steps to configure the BMC to support IPMI-based node fencing.
• Configuring the iLO Processor on HP-UX
  Review this procedure to configure IPMI in the iLO processor on HP platforms, and to set a password for the null (noname user).
