Managing ProLiant servers with Linux HOWTO

For Red Hat and SuSE systems:

# service hp-health stop

# service hp-snmp-agents stop

3-3 Parameters

This section lists parameters for various agents and services.

Table 10 includes the command line arguments that can be passed to the NIC agents (cmanicd) from

the /opt/hp/hp-snmp-agents/nic/etc/cmanicd script.

Table 10. Parameters for NIC agents

Parameter Description

-p poll_time This parameter specifies the number of seconds between data caching and poll intervals. NIC drivers are

only queried when a request comes in and the cached information is older than the specified poll interval.

The default value is 20 seconds. The minimum poll time is 10 seconds.

-s set_state This parameter specifies whether SNMP set commands are allowed for this agent. A set_state of OK

(default) means that SNMP set commands are allowed. A set_state of NOT_OK means that SNMP set

commands are not allowed.

-t trap_state This parameter specifies whether the NIC Agent is allowed to send traps or not. A trap_state of OK (default)

indicates the NIC Agent can send SNMP traps. A trap_state of NOT_OK means that the NIC Agent is not

allowed to send traps.

For example, to set the poll interval to 30 seconds and prevent traps, change PFLAGS= to PFLAGS="-

p30 -t NOT_OK" in the /opt/hp/hp-snmp-agents/nic/etc/cmanicd script.

Traps are configured using the standard SNMP configuration file (snmpd.conf). See the snmpd.conf

manual page for the most current configuration information. When the snmpd.conf or

snmpd.local.conf configuration files are changed or when the SNMPCONFPATH environment

variable is changed, the cmanic daemon must be restarted.

If your operating system has an active firewall configuration, external SNMP requests might be

rejected by the system, which prevents remote management operation. Your system must be

configured to allow udp connections on port 161 from any hosts that need to be able to send SNMP

requests. There are significant security implications to configuring a firewall. Consider the iptables,

ipchains, iptables-save, and iptables-restore man pages and the documentation for any firewall

configuration application in use as mandatory reading before making any change to the firewall

configuration.

The Rack Infrastructure Interface Service is contained in an executable called cpqriisd which resides in

the /sbin directory. It can be invoked by using the commands in Table 11.

Table 11. Command options for the Rack Infrastructure Service

Option Description

-F This option will "daemonize" the process and start the daemon in a production level environment. Usage is

recommended. An easier way to accomplish this task is to execute the hp-snmp-agents run-level script.

-D This option starts the service in a debug environment. stdin and stdout go to the console; typing "e" will stop the

daemon. Alerts are logged in to the same text console.

-V This option enables the verbosity of the output. The default behavior is to output to both /var/log/messages and

tty1 – tty10.

-? This option reports the version of the service and informs the user of the other options described above.
