Guardian Procedure Errors and Messages Manual

About This Manual
Purpose of This Manual
This manual describes the Guardian messages for HP systems that use the HP NonStop operating
system. It covers the following types of messages:
• The error codes and error lists associated with Guardian procedure calls
• The interprocess messages sent to application programs by the operating system and the
command interpreter
• The trap numbers, signals, and the error list for traps and signals
Each message description explains the cause of the message, states the effect on the system, and
provides a recommended recovery action.
Who Should Read This Manual
This manual is intended mainly for application programmers whose programs call Guardian
procedures directly. Applications can check for errors returned by these procedures, and subsequent
action can be initiated based on the error returned.
Other users who can benefit from this manual include interactive users of HP NonStop systems,
system managers, and system operators.
How This Manual Is Organized
