Error description
In case applications like GDPS are using a SA-BCPii connection to perform System z HW operations management, the SA HW validation function may interrupt such a connection uncoordinated in order to keep real HW configuration and SA stored configuration data in sync. With this NF fix, a method will be provided to permanently suppress this SA HW validation behaviour to synchronize the configuration data. At runtime, SA-BCPii sessions will no longer be recycled for this reason.

Comments
1. SA-BCPII HW VALIDATION CNTL FUNCTION --------------------------------------- Cmd INGRX815/INGHWSRV was changed to allow set/unset of the new BCPIIPRIO option. If this option is set to 'GDPS', a SA ACF- COLD action with a changed processor configuration will no longer terminate and restart BCPii connections to processors names when found in the GEOPLEX domain/option definitions.The SA.GDPS tower must be enabled. Internal BCPii management clists INGRX806, INGRVX80 were changed to check and follow the new BCPIIPRIO flag. New messages: ING820I - ING823I DSIING82, ING82 Doc changes: Msg & Codes, Operator's Commands 2. BLOCK UNWANTED PPT USAGE --------------------------- Internal clist INGRX810/INGHWCMD was changed. New validation step is implemented to check that the operator executing the SA hardware command is *NOT* a PPT task. Some NetView commands used by SA hardware commands, e.g. 'WAIT', cannot run under PPT task and will flood the log with messages like e.g. "DSI198I TASK'WAIT' COMMAND NOT ALLOWED TO RUN UNDER xxx TASK ." If the check detects that the oper id is a PPT task, hardware command execution will be rejected and a new AOFA0000 error report will be issued: Command_not_allowed_to_run_under_PPT_task_xxxxx. Doc changes: Msg & Codes 3. INGRX815/INGHWSRV ADD-ONs ---------------------------- The diagnostic and service support command has been enhanced. Beside the BCPIIPRIO option flag, mentioned under 1., the following new options have been added: CONNECT, SUSPEND, RESUME Doc changes: Msg & Codes, Operator's Commands 4. SPEED-UP INITCOM ------------------- The EC level query for the connected console (SE/HMC) was removed from the INITCOM discovery logic and placed in the hardware common command CONDATA, instead. This unilateral SW action was made in accordance with IBM's action plan to resolve this zEC12 hardware based performance issue. Module INGHWCOM/INGCHW0A/INGCHW0D was changed for this. Note, that this action can speed-up INITCOM processing for ProcOps SNMP and SA-BCPii connection, but does not resolve the root cause in the System z console zEC12 D/T2827 . 5. INTERNAL FINDINGS -------------------- Module INGHWCOM/INGCHW0C was changed to correct the processing of internally issued session terminations, in cases when these terminations fail. Module INGHWCOM/INGCHW0E was changed to fix the wrong handling of the security-log event data packet length. Module INGHWCOM/INGCHW0E was changed to no longer ignore a sub-set of HwmcaWaitEvent return codes. New msg: ING809I 6. PREPARATION FOR FUTURE HARDWARE AND SOFTWARE ----------------------------------------------- Module INGHWCOM/INGCHW00 was prepared. 7. OTHER -------- INGHWCOM/INGHW0VN set to Aparlevel for DISPMOD. For SA34 only: Module HSAPHCPR of INGHWCOM/INGCHW00 was auto-compiled by the build system and therefore added to fixlist. Reason=macro change.
