Abnormal termination of Cluster Manager daemon

Edit online

The AIX® resource controller subsystem monitors the cluster manager daemon process. If the controller detects that Cluster Manager daemon has exited abnormally (without being shut down using the clstop command), it executes the /usr/es/sbin/cluster/utilities/clexit.rc script to halt the system. This prevents unpredictable behavior from corrupting the data on the shared disks.

See the clexit.rc man page for additional information.

The clexit.rc script creates an AIX error log entry. Here is an example showing the long output:

clexit.rc : Unexpected termination of clstrmgrES

The clexit.rc error message in short form looks like this:

AA8AB241   0107104400 T O OPERATOROPERATOR NOTIFICATION

Important: Never use the kill -9 command on the clstrmgr daemon. Using the kill command causes the clstrmgr daemon to exit abnormally. This causes the System Resource Controller (SRC) facility to run the script /usr/es/sbin/cluster/utilities/clexit.rc , which halts the system immediately and causes the surviving nodes to initiate fallover.

You can modify the file /etc/cluster/hacmp.term to change the default action after an abnormal exit. The clexit.rc script checks for the presence of this file, and if you have made it executable, the instructions there will be followed instead of the automatic halt called by clexit.rc . Please read the caveats contained in the /etc/cluster/hacmp.term file, however, before making any modifications.
