HP XC System Software Installation Guide Version 2.1

Verifying the System

Follow the procedures described in this chapter to verify the successful installation and

configuration of the XC system components. HP recommends that you p erform all tasks

described in this chapter:

1. Run the operation verification program to verify the integr ity of th e installati on and

configuration of your XC system (Section 5.1).

2. Create a baseline snapshot of the system configuration database (Section 5.2).

3. Run the sys_check utility (Section 5.3).

5.1 Run the Operation Verification Program (OVP)

The OVP verifies the major XC system components to provide a level of confidence that the

software has b een 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 Administrative Network is operational

• A valid l icense key file is installed and the license manager servers are u p

• All compute nodes are responding and are available to run applications

• SLURM control daemons are responding and CPU partitioning is valid

• LSF HPC is up and ru nning

•Thexring test verifies the MPI compiler and launches and executes an MPI job

• Serial and parallel ap plications can be submitt ed and executed through SLURM an d L SF

HPC from all compute nodes

Follow this procedure to test your 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

Successful com mand output is similar to the following:
