HP XC System Software Installation Guide Version 3.0

5 Verifying the System
Complete the tasks described in this chapter to verify the successful installation and configuration of the HP
XC system components. HP recommends that you perform all tasks described in this chapter.
• Task 1: Run the Operation Verification Program (OVP) (page 67)
• Task 2: Take a Snapshot of the Database (page 72)
• Task 3: Create a Baseline Report of Your System Configuration (page 72)
Task 1: Run the Operation Verification Program (OVP)
The OVP verifies the major HP XC system components to provide a level of confidence that the software has
been installed correctly and the system is functioning and operational.
The OVP performs various tests to verify the following:
• The interconnect is functional.
• Network connectivity has been established.
• The administration network is operational.
• A valid license key file is installed and the license manager servers are up.
• All compute nodes are responding and are available to run applications.
• SLURM control daemons are responding and partitioning is valid.
• LSF-HPC with SLURM or standard LSF is up and running.
• The xring test verifies the MPI compiler and launches and executes an MPI job
• Serial and parallel applications can be submitted and executed through standard LSF or LSF-HPC with
SLURM from all compute nodes.
Follow this procedure to test your HP XC system:
1. Begin this procedure as the root user on the head node.
2. Start the verification procedure, without any options, to test the entire system:
# ovp --verbose
Command output is similar to the following. This example output was taken from a small system that
has LSF-HPC with SLURM installed. Output looks different on a system with standard LSF.

Verify connectivity:
Testing etc_hosts_integrity ...
There are 19 IP addresses to ping.
A total of 19 addresses were pinged.
Test completed successfully. All IP addresses were reachable.

Verify client_nodes:
Testing hptc_cluster_mount ...
Determining nodes that provide the hptc_cluster_fs_client service.
6 nodes provide the hptc_cluster_fs_client service.
