HP XC System Software Administration Guide Version 3.0

For a complete list of verification tests, see ovp(8).
Note
Run the ovp command only when you have exclusive use of the HP XC system and no jobs are running on
the system.
Normally you do not need to run this utility after you run it at the end of the HP XC system installation;
however, it is recommended that you run this utility regularly to verify the health of the HP XC system.
The ovp command has the following syntax:
ovpoptions
The available options include the following:
--list[=pattern] Lists the verification tests that match the specified pattern. If the pattern
is unspecified, the default tests are listed.
--verify pattern Runs verification tests. This is the default action.
--failure_action=[E|I|S] Specifies the action to be taken if a test fails. These are the values for
this option:
E Exit immediately if the test fails.
I Ignore test failures. This is the default action.
S Skip the remaining tests in the same group. They are
considered failed tests as well.
--verbose Displays additional test output.
--help=[tests|pattern] Displays information on the ovp command or its tests.
Depending on the type of change you make or problem you encounter, you can run the appropriate ovp
test or tests. To list the available verification tests, enter the ovp command with the -l option, as in this
example:
# ovp -l
Test list for 'connectivity':
etc_hosts_integrity
Test list for 'license':
file_integrity
server_status
Test list for 'SLURM':
daemon_responds
sinfo
Test list for 'LSF':
identification
Test list for 'interconnect':
quadrics/qsnet_database
quadrics/swmlogger
quadrics/network
Test list for 'cluster':
xring (X)
You can select the appropriate test by pattern. Also, you can enter multiple selections by separating them
with commas.
To verify HP XC licensing, enter a command in the following format:
# ovp -v=license
By default, if any part of the verification fails, the ovp command ignores the test failure and continues with
the next test. You can use the --failure_action option to control how the ovp command treats test
failures.
The ovp command stores a record of the verification in a log file in the /hptc_cluster/adm/logs/ovp
directory. The file name for log files has the form verify_nodename_mmddyy; the mmddyy portion is a
date stamp in month, day, year form. The file named current in that directory is a symbolic link to the
most recent log file.
