Most errors are due to mismatched community strings entered during agent configuration on the managed server. Follow these steps , which include confirming the community string settings, before performing more advanced troubleshooting: Examine the SNMP daemon configuration file. If your system is running RHEL, this file is located in /etc/snmp/snmpd.conf. If your system is running SLES, this file is located in /etc/snmpd.conf. The first set of directives should be delimited by the following comment lines (the date should reflect your installation time).

 |  |  |  |  | NOTE: Any remote host names you configured during initial installation appear in this file. Record these remote host names for later use in “Advanced Troubleshooting Steps”. |  |  |  |  |
Find the directives for local host community strings. In the following example, ROlocal and RWlocal are used as a generic representations of the names you set for the read-only and read-write community strings, respectively. The names in your file appears as you configured them when you installed the HP Insight Management Agents. rocommunity ROlocal 127.0.0.1 rwcommunity RWlocal 127.0.0.1 Ensure the values of ROlocal and RWlocal are what you thought you set for local host community strings when you configured or reconfigured your agents. Each community string must have a unique string value. If you need to change them, see the instructions in “Reconfiguring HP Insight Management Agents”.  |  |  |  |  | NOTE: The rocommunity ROlocal string, if it exists, must come before the rwcommunity <RWlocal> community string in the file. |  |  |  |  |
Find the directives for remote host community strings: rocommunity ROremote remote host name rwcommunity RWremote remote host name You should see a pair of lines for both the ROremote and the RWremote management stations you specified during agent installation. Ensure the community string values of ROremote and RWremote are what you specified during agent configuration. Also remember that the community string value of ROremote must be different from RWremote for a single remote host. These community strings may be reused on other remote hosts.  |  |  |  |  | NOTE: The rocommunity ROremote string, if it exists, must come before the rwcommunity RWremote community string in the file. |  |  |  |  |
Verify that the community strings and host names match what you think you configured them to be, and that they also match the settings in your management console software (HP SIM). If they do not match, follow the directions in “Reconfiguring HP Insight Management Agents”.
