Managing ProLiant servers with Linux HOWTO

The keyword "trapemail" indicates that the rest of the line is the command for sending trap email. In

mail_command, you must provide the full path of your email command, the subject, and the

recipients.

Multiple trapemail lines can be defined in /opt/hp/hp-snmp-agents/cma.conf. A default line is added

during installation if none exists:

trapemail /bin/mail -s 'HP Insight Management Agents Trap Alarm' root

The mail_command can be any Linux command that reads standard input. For example, using

trapemail /usr/bin/logger will log trap messages to the system log file (/var/log/messages).

The cmaXSocketBase entry in configuration file /opt/hp/hp-snmp-agents/cma.conf configures the

starting socket port used for communications between cmaX and Peers. The entry is not needed unless

the "bind() failed!" message displays in the Agents log file /var/spool/compaq/cma.log.

This entry should be listed in the configuration file as follows:

cmaXSocketBase 12345

The trapIf entry in configuration file /opt/hp/hp-snmp-agents/cma.conf can be used to configure the

IP address used by the SNMP daemon when sending traps. For example, to send traps using the IP

address of the eth1 interface you would add:

trapIf eth1

If the cmaXSocket Base entry is edited, the snmpd and Peers software must be restarted before the

configuration modification is effective. You can do this by entering the following commands:

#/etc/init.d/snmpd restart

#/etc/init.d/hp-snmp-agents restart

You can also manipulate the /opt/hp/hp-snmp-agents/cma.conf file which contains one or more

exclude directives. Any string after the exclude keyword is interpreted as an agent name that should

not be started. Examples include:

exclude cmahealthd

exclude cmastdeqd

These two lines exclude two agents from the startup: the Health Agent (cmahealthd) and the Standard

Equipment Agent (cmastdeqd).

3-2 Starting and stopping agents and services

After the initial installation, both the ProLiant Management Agents and the Health Monitor are loaded.

Upon a reboot, the initscripts /etc/init.d/hp-health and /etc/init.d/hp-snmp-agents reload the Health

Monitor and SNMP agents and drivers, even if a different kernel was used for the new run.

To start and stop the hp-health service at runtime, run:

# /etc/init.d/hp-health stop

# /etc/init.d/hp-health start

To start and stop the hp-snmp-agents at runtime, run:

# /etc/init.d/hp-snmp-agents stop

# /etc/init.d/hp-snmp-agents start

You can also use distro-provided shortcuts for these commands.
