Modifying IPMI Configuration Using CRSCTL

To modify an existing IPMI-based failure isolation configuration (for example to change IPMI passwords, or to configure IPMI for failure isolation in an existing installation), use CRSCTL with the IPMI configuration tool appropriate to your platform. For example, to change the administrator password for IPMI, you must first modify the IMPI configuration as described in Oracle Grid Infrastructure Installation Guide, and then use CRSCTL to change the password in OLR.

The configuration data needed by Oracle Clusterware for IPMI is kept in an Oracle Wallet in OCR. Because the configuration information is kept in a secure store, it must be written by the Oracle Clusterware installation owner account (the Grid user), so you must log in as that installation user.

Use the following procedure to modify an existing IPMI configuration:

Enter the crsctl set css ipmiadmin administrator_name command. For example, with the user IPMIadm:
```
crsctl set css ipmiadmin IPMIadm
```
Provide the administrator password. Oracle Clusterware stores the administrator name and password for the local IPMI in OLR.

After storing the new credentials, Oracle Clusterware can retrieve the new credentials and distribute them as required.
Enter the crsctl set css ipmiaddr bmc_ip_address command. For example:
```
crsctl set css ipmiaddr 192.0.2.244
```
This command stores the new IPMI IP address of the local IPMI in OLR, After storing the IP address, Oracle Clusterware can retrieve the new configuration and distribute it as required.
Enter the crsctl get css ipmiaddr command. For example:
```
crsctl get css ipmiaddr
```
This command retrieves the IP address for the local IPMI from OLR and displays it on the console.
Remove the IPMI configuration information for the local IPMI from OLR and delete the registry entry, as follows:
```
crsctl unset css ipmiconfig
```
