Return codes

When the service returns control to the caller, GPR 15 and ReturnCode contain a hexadecimal return code.

Return Code in Hexadecimal Equate Symbol	Meaning and Action
0 HWI_OK	Meaning: Successful completion. Action: None.
100 HWI_CONNECT_TOKEN_INV	Meaning: Program error. The specified connect token is not valid. This return code indicates that one of the following conditions has occurred: The input connection token does not exist. A previous HWICONN service call has never returned the value specified on OutConnectToken. The connect token does not represent an active connection. The connection specified might have already been disconnected using the HWIDISC service call. The connect token is not associated with the address space of the caller. The ConnectToken specified is associated with a different address space than the caller of this service call. Action: Check for probable coding error.
101 HWI_COMMUNICATION_ERROR	Meaning: A communication error is detected. The hardware management console application API (HWMCA) or the BCPii transport layer has returned with a failing return code. Action: See the DiagArea for further diagnostic information. The Diag_CommErr indicates the return code that is returned from HWMCA APIs or the BCPii transport layer. HWMCA API and BCPii transport return codes are provided in BCPii communication error reason codes.
102 HWI_DIAGAREA_INV	Meaning: Program error. The DiagArea is not accessible. Action: Check for probable coding error. Verify that the specified DiagArea is defined as a 32-byte character field.
901 HWI_DISC_INPROGRESS	Meaning: Another Disconnect request is already in progress. This request is redundant. Action: None.
F00 HWI_NOT_AVAILABLE	Meaning: BCPii services are not available, and the system rejects the service request. Action: Notify the system programmer to start the BCPii address space and try the request again. See Restarting the HWIBCPii address space about how to start the BCPii address space. Programs can also listen to ENF68 to determine when BCPii services are available. See z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG for how to listen for BCPii activation messages.
F01 HWI_AUTH_FAILURE	Meaning: The caller is PKM8-15 problem state and the program does not reside in an APF-authorized library. Action: Check the calling program for a probable coding error.
F02 HWI_NO_SAF_AUTH	Meaning: The user does not have correct SAF authorization for the request. Action: Check for probable error. Consider one or more of the following possible actions: Define read access authorization to the FACILITY class resource profile HWI.APPLNAME.HWISERV. Define read access authorization to the FACILITY class resource profile HWI.TARGET.netid.nau for a CPC, activation profile, or image group connection. Define read access authorization to the FACILITY class resource profile HWI.TARGET.netid.nau.imagename for an image connection. Define read access authorization to the FACILITY class resource profile HWI.CAPREC.netid.nau.caprecid for a capacity record connection. Ensure that the referenced Facility Class Profiles are RACLIST-specified.
F03 HWI_INTERRUPT_STATUS_INV	Meaning: The calling program is disabled. The system rejects this service request. Action: Check the calling program for a probable coding error.
F04 HWI_MODE_INV	Meaning: The calling program is not in task mode. The system rejects this service request. Action: Check the calling program for a probable error.
F05 HWI_LOCKS_HELD	Meaning: The calling program is holding one or more locks. The system rejects this service request. Action: Check the calling program for a probable coding error.
F06 HWI_UNSUPPORTED_RELEASE	Meaning: The system level does not support this service. The system rejects this service request. Action: Remove the calling program from the system, and install it on a system that supports BCPii services. Then run the calling program again.
F07 HWI_UNSUPPORTED_ENVIRONMENT	Meaning: The system does not support execution of the service from the current environment (for example, calling a BCPii service from within a BCPii ENF exit routine). Action: Issue the BCPii service from a different execution environment.
FFF HWI_UNEXPECTED_ERROR	Meaning: System error. The service that was called encountered an unexpected error. The system rejects the service call. Action: Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM Support Center.
