Configuring the SP proxy agent

The SP proxy agents (sp_configd) residing on each managed SP node and control workstation are configured to be started automatically whenever AIX is started. The configuration changes necessary to accomplish this are performed during installation on the nodes and the control workstation.

If you have a management station that "listens" for traps, place the information for the trap destination in the /etc/snmpd.conf file on each SP node and control workstation. Instructions for doing this are in the /etc/snmpd.conf file. The following steps are performed automatically by the syspar_ctrl script on each node and the control workstation when the PSSP software is installed:

1. These steps presume that the standard AIX Agent is already configured to be managed by the desired Managers. If this is not the case, see the information contained in the /etc/snmpd.conf file for required updates to the file. This update must be made on every SP node and the control workstation.
2. The /etc/snmpd.conf file is modified to add the SP subagent (sp_configd) to the set of SMUX peers with a "smux" record
3. The SP MIB file /usr/lpp/ssp/config/snmp_proxy/ibmSPMIB.defs is appended to the /etc/mibs.def file. The /usr/lpp/ssp/config/snmp_proxy/ibmSPMIB.defs file is compiled from ibmSPMIB.my
4. Information for the new sp_configd subagent is added to the /etc/snmpd.peers file. The information is the OID of the Agent and the community name (password).
5. The snmpd daemon is refreshed.
6. The daemon is started under SRC control.
   1. An src_entry for sp_configd is added to the AIX Object Data Manager (ODM) so that the daemon can be controlled using the startsrc command. The src_entry invokes the startsrc command with the following parameters:

      -s sp_configd -a "-t 600" -p /usr/lpp/ssp/bin/spconfigd
      -u 0 -i /dev/null -o /dev/null -e /dev/null -S -n 15 -F 15
      

   2. An entry is added to the AIX inittab file to start the daemon by issuing the command:

      /usr/bin/startsrc -s sp_configd
      

   3. The sp_configd daemon supports a -t switch that determines the amount of time (in seconds) for which data is to be cached by the daemon and re-fetched when a new request for the data is received. The default value is 60 seconds. The default can be changed in the src_entry or the startsrc command contained in the inittab file, or by entering startsrc at the command line.
   4. The daemon can be stopped by issuing:

      /usr/bin/stopsrc -s sp_configd
