Removing IPMI Configuration Using CRSCTL

You can remove an IPMI configuration from a cluster using CRSCTL if you want to stop using IPMI completely or if IPMI was initially configured by someone other than the user that installed Oracle Clusterware. If the latter is true, then Oracle Clusterware cannot access the IPMI configuration data and IPMI is not usable by the Oracle Clusterware software, and you must reconfigure IPMI as the user that installed Oracle Clusterware.

To completely remove IPMI, perform the following steps. To reconfigure IPMI as the user that installed Oracle Clusterware, perform steps 3 and 4, then repeat steps 2 and 3 in "Modifying IPMI Configuration Using CRSCTL".

  1. Disable the IPMI driver and eliminate the boot-time installation, as follows: 
    /sbin/modprobe –r

    See Also:

    Oracle Grid Infrastructure Installation Guide for your platform for more information about the IPMI driver

  2. Disable IPMI-over-LAN for the local IPMI using either ipmitool or ipmiutil, to prevent access over the LAN or change the IPMI administrator user ID and password.
  3. Ensure that Oracle Clusterware is running and then use CRSCTL to remove the IPMI configuration data from OLR by running the following command: 
    crsctl unset css ipmiconfig
  4. Restart Oracle Clusterware so that it runs without the IPMI configuration by running the following commands as root: 
    # crsctl stop crs
# crsctl start crs
