Error Messages

SCF displays an error message when it cannot complete the requested action. This

happens when the command is entered incorrectly or is not appropriate for some reason

(for example, the target object cannot be found or is not in the required state, or the user

does not have a proper user ID to perform a sensitive command).

Subsystem Identifier

Error messages for SCF commands sent to Compaq OSI/MHS processes can originate

from the OSI/MHS subsystem or from SCF. Each error message is preceded by the

name of the subsystem that returns the error. Errors returned by the OSI/MHS

subsystem are identified by the string MHS and errors returned by SCF are identified by

the string SCF.

Common Versus Subsystem-Specific Errors

SCF provides a pool of error messages that can be used by all subsystems, called

“common errors.” These errors always have negative error numbers. The OSI/MHS

subsystem uses these common errors.

The OSI/MHS subsystem also can generate error messages that pertain solely to that

subsystem, called “subsystem-specific” error messages. These errors always have

positive error numbers.

For each error, therefore, you must look at the subsystem identifier to see which

subsystem returned the error, and look at the error number to determine whether it is a

common error or a subsystem-specific error.

For more information on error messages, see the following:

Type of Error Message Where To Find Additional Information

Common errors

(negative-numbered errors)

The Subsystem Control Facility (SCF) Reference

Manual contains general information on the cause and

recovery of each common error.

OSI/MHS subsystem-specific errors

(positive-numbered errors)

Appendix B, OSI/MHS SCF Error Messages

, in this

manual contains general (non-command-specific)

cause, effect, and recovery information for all

subsystem-specific errors returned by the OSI/MHS

subsystem.

Other subsystem-specific errors

from underlying subsystems

(positive-numbered errors)

The SCF reference manual for each underlying

subsystem contains descriptions of the subsystem-

specific error messages returned by that subsystem.
