You initiate the validation checksfunctionality when you issue the ndu -install command. Thevalidation checks run in the background, prior to installing thesoftware. If a validation check fails, the CLI displays the error andterminates the installation. You can choose to display all validationchecks as the functionality executes by specifying the -verboseswitch, otherwise the CLI only displays failures that preventinstallation. The following responses exist for each validation check:ResponseSuccessfulWarningFailureDefinitionValidation check is successful. Installation proceeds.Conditions exist that may need correction.
