Enabling clinfo for asynchronous event notification

Edit online

In PowerHA® SystemMirror®, the clinfo daemon obtains data only from Simple Network Management Protocol (SNMP). You can configure PowerHA SystemMirror to use the clinfo daemon to receive notification of events as asynchronous messages (otherwise known as traps).

About this task

Only one SNMP application can receive traps. If your system is running the NetView® for AIX® licensed product, you cannot enable the clinfo daemon to receive traps.

To enable asynchronous event notification, complete the following steps:

Procedure

To start the clinfo daemon, enter chssys -s clinfoES -a "-a" from the command line.
To verify that the System Resource Controller (SRC) has the correct command-line arguments for the clinfo daemon, enter lssrc -Ss clinfoES from the command line.
Edit the /etc/snmpdv3.conf file on the nodes that sends traps. As installed, traps are directed to the loopback address. The clinfo daemon receives traps that are generated by the Cluster Manager on the same node. Review the comments at the beginning of the /etc/snmpdv3.conf file for a description of all fields.
Note: SNMP version 3 is the default version that is used by the AIX operating system.
1. Find the trap line at the end of the file. The following code is an example of the trap line:
```
view   1.17.2  system enterprises view
trap  public  127.0.0.1   1.2.3 fe  # loopback
```
2. Add trap lines as wanted. Multiple clinfo daemon processes can receive traps from the Cluster Manager. Make sure that the 1.2.3 fe field is unique.
  The following is an example with two more trap lines added:
```
trap  public  127.0.0.1   1.2.3 fe  #loopback
trap  public  123.456.789.1#adam
trap  public  123.456.789.2#eve
```
3. Stop the snmpd daemon on the hosts where you changed the /etc/snmpdv3.conf file, enter stopsrc -s snmpd from the command line.
4. Start the snmpd daemon on the hosts where you changed the /etc/snmpdv3.conf file, enter startsrc -s snmpd from the command line.
