HP XC System Software Administration Guide Version 3.2

• The administration network is operational.
• All application nodes are responding and available to run applications.
• The nodes in the HP XC system are performing optimally. These nodes are tested for the
following:
— CPU core usage
— CPU core performance
— Memory usage
— Memory performance
— Network performance under stress
— Bidirectional network performance between pairs of nodes
— Unidirectional network performance between pairs of nodes
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.
The ovp command is primarily a tool run at the end of the HP XC system installation to verify
its operation. However, you can use it at any time to verify the health of the HP XC system.
The ovp command has the following syntax:
ovp options
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
