2.4.1 Notes about installation (for HP-UX (IPF))
This subsection provides HP-UX (IPF)-specific notes about installation when SNMP Agent for HP-UX (IPF) system is installed. For notes common to all OSs, see 2.4 Notes about installation.
-
When SNMP Agent is installed, some of the OS files are changed.
SNMP Agent uses the 161/udp port as the SNMP packet reception port. Only one process can connect to this 161/udp port. If both the native agent and SNMP Agent are started, the native agent is set to not start automatically during OS startup so that SNMP Agent can always connect to the 161/udp port. If SNMP Agent is uninstalled, the original names are restored. The following shows the file names before and after the change.

If snmp 161/udp is not defined in the /etc/services file, it is added to the /etc/services file.

If you install SNMP Agent on the same host as for NNM, make sure that the required directories exist.
If you install SNMP Agent on the same host as for NNM, the directories shown below must exist when SNMP Agent is installed. Take precautions especially in the case of a cluster system.
-
/var/opt/OV/share
-
/etc/opt/OV/share
SNMP Agent creates files under these directories during installation. If these directories do not exist, installation fails.
-
-
During SNMP Agent installation, the following files are replaced with files provided by SNMP Agent:
-
/etc/srconf/agt/snmpd.cnf
-
/etc/srconf/mgr/mgr.cnf
-
/etc/srconf/mgr/snmpinfo.dat
If any of these files already exist when SNMP Agent is installed, they are saved in the SNMP Agent installation directory during installation of SNMP Agent (under /opt/CM2/ESA/newconfig). These saved files are restored if SNMP Agent is uninstalled.
