•The run number, which represents the number of times the OVP has been run. The run number is not included for the first run.

For example, the log file name ovp_ n16_070607.log indicates that this is the first run of the OVP on July 06, 2007, on head node n16.

5.For more information about troubleshooting failed test results, see HP XC System Software Installation Guide.

For information about verifying individual cluster components on demand, see ovp(8) and the HP XC System Software Administration Guide.

If you receive errors or warnings from the OVP, try synchronizing the nodes:

# setnode --resync --all

5.12Nagios Web Interface

Nagios is the system and network health monitoring application on an HP XC system. It watches hosts and services and alerts you when problems occur or are resolved.

TIP: HP recommends that you start up the Nagios web interface now to view the network and ensure that all hosts and services are in the green state.

To open the Nagios web page, follow these steps:

1.Open a browser on the head node.

2.Enter the following web address in the Address field: https://fully_qualified_HP_XC_hostname/nagios

3.When prompted, log in as the nagiosadmin user and specify the Nagios administrator password.

If the hardware configuration contains less than 100 nodes, the Service Detail view provides a good overview of the system. It lists the Nagios hosts and shows their status.

The Service Problems view is more useful for hardware configurations with hundreds or thousands of nodes. It provides a practical overview of the system.

For more information about how to use Nagios, see the HP XC System Software Administration Guide.

5.13 The nrg Command

The nrg command uses data collected by the Nagios utility to generate reports. Use the summary option to display a summary of defined Nagios services and the state of those services. For example:

# nrg --mode summary
