IPMI Postinstallation Configuration with Oracle Clusterware

When you install IPMI during Oracle Clusterware installation, you configure failure isolation in two phases. Before you start the installation, you install and enable the IPMI driver in the server operating system, and configure the IPMI hardware on each node (IP address mode, admin credentials, and so on), as described in Oracle Grid Infrastructure Installation Guide. When you install Oracle Clusterware, the installer collects the IPMI administrator user ID and password, and stores them in an Oracle Wallet in node-local storage, in OLR.

After you complete the server configuration, complete the following procedure on each cluster node to register IPMI administrators and passwords on the nodes.

Note:

If IPMI is configured to obtain its IP address using DHCP, it may be necessary to reset IPMI or restart the node to cause it to obtain an address.

Start Oracle Clusterware, which allows it to obtain the current IP address from IPMI. This confirms the ability of the clusterware to communicate with IPMI, which is necessary at startup.
If Oracle Clusterware was running before IPMI was configured, you can shut Oracle Clusterware down and restart it. Alternatively, you can use the IPMI management utility to obtain the IPMI IP address and then use CRSCTL to store the IP address in OLR by running a command similar to the following:
```
crsctl set css ipmiaddr 192.168.10.45
```
Use CRSCTL to store the previously established user ID and password for the resident IPMI in OLR by running the crsctl set css ipmiadmin command, and supplying password at the prompt. For example:
```
crsctl set css ipmiadmin administrator_name
IPMI BMC password: password
```
This command validates the supplied credentials and fails if another cluster node cannot access the local IPMI using them.

After you complete hardware and operating system configuration, and register the IPMI administrator on Oracle Clusterware, IPMI-based failure isolation should be fully functional.
