GDDR: Opgradering til z/OS 2.5 får abends og GDDR Control SYSTEMS til at køre i forringet tilstand
Summary: Opgradering til z/OS 2.5 medfører afvigelser i geografisk spredt genstart efter nedbrud (GDDR), og GDDR Control SYSTEMS (C-SYS) kører i forringet tilstand.

Symptoms
Mainframe-operativsystemets software opdateres til z/OS 2.5-softwareniveau med vedligeholdelsestolerance. z/OS 2.5 bruges til en ny IBM z16-CPU.
GDDR GDDRMAIN startede op med flere ABEND'er, efter at z/OS-vedligeholdelsen blev anvendt:
- HBM rapporterer nedenstående fejl ved GDDRMAIN-opstart, GDDR-værten er i forringet tilstand:
ABEND S0E0-29
- GDDRRPT rapporterer nedenstående fejl ved GDDRMAIN-nedlukning:
ABEND S0E0-28
Følgende fejlmeddelelser sendes i GDDR Event Monitor (EVM) og Heartbeat Monitor (HBM) output:
GDDUG86E No matching GDDR systems found
Hvis ABEND S0E0-28 forekommer ved GDDRMAIN-nedlukning, derefter en Abend S067-04 kan forekomme, hvis GDDRMAIN bringes op igen.
Cause
En
Derudover har en
ABEND S0E0-29 kan forekomme ved GDDRMAIN-start i HBM-underopgaven på modul GDDREVMI, offset 0005AF74.
PSW 183158F0 0010D507 3000F154Dette får HBM-underopgaven til at afslutte og efterlader GDDRMAIN uden funktioner til overvågning af hjerteslag. GDDR-værten kører i forringet tilstand. GDDREVMI opdateres for at rydde REGISTRER AR15, før du bruger registret for at undgå en
ABEND S0E0-29.
Derudover har en
ABEND S0E0-28 kan forekomme i GDDRRPT ved GDDRMAIN-nedlukning ved GDDRMAIN, forskydning 0006EAB2.
PSW D24FD37A 1000D207 D37D5004GDDRRPT opdateres for at rydde REGISTRER AR1 for at undgå en
ABEND S0E0-28. GDDRMAIN opdateres for at kontrollere, at ALET (Access List Entry Token) er gyldig i dataområde 2. Denne handling udføres, før du får adgang til dataområdet for en anden GDDR-forekomst. Denne handling hjælper med at undgå en Abend S067-04 i GDDRMAIN-opstarten på grund af en anden GDDR-forekomst, der ikke lukker rent ned.Resolution
Løsning:
- Ingen til ABEND S0E0-29, men GDDR-værterne fortsætter med at køre i forringet tilstand.
- Der kræves en indledende programbelastning (IPL) af den logiske partition (LPAR) for at rydde hukommelsen, hvis en
Abend S067-04Opstår.
Permanent løsning:
- Til GDDR 6.0 kan PTF-GD60004 (Program Temporary Fix) og GD60005 downloades fra Dell Support.
- For GDDR 6.1 løses problemet i basisproduktet. Den kan downloades fra Dell Support.

*-------------------------------------------------------------
* PROBLEM DESCRIPTION(S):
* ------------------------------------------------------------
*
* PROBLEM FIXED: GDDR-3459
* USERS AFFECTED: GDDR users
* PROBLEM DESCRIPTION: Warning message GDDUG24W results in
* RC 8 on pre-script and post-script
* configuration displays
*
* DESCRIPTION DETAIL:
*
* During GDDR scripts, warning message GDDUG24W could result
* in an RC 8 on the pre-script and post-script configuration
* displays, for example:
*
* GDDUG24W 2 external RDF groups indicate SRDF/A active
* GDDR639I GDDR Completed pre-script configuration display
* with rc 8
*
* This is simply a messaging issue, as a non-zero RC on the
* configuration displays does not affect the outcome of the
* script.
*
* PROBLEM RESOLUTION:
*
* Warning message GDDUG24W will now result in an RC 4 on the
* configuration displays, as expected.

* PROBLEM DESCRIPTION: ABENDS067-04 upon GDDRMAIN startup due
* to another GDDR instance not shutting
* down cleanly
*
* DESCRIPTION DETAIL:
*
* An S067-04 abend could occur upon GDDRMAIN startup at
* GDDRMAIN offset 000006AC (data at PSW 4038B219 02009540
* 50E8B219) if another GDDR instance was not shut down
* cleanly. This causes GDDRMAIN to terminate.
*
* PROBLEM RESOLUTION:
*
* An S067-04 abend should no longer occur upon GDDRMAIN
* startup if another GDDR instance was not shut down cleanly.
*
* In addition, the GDDRMAIN ESTAE routine has been improved to
* ensure that GDDRMAIN is shut down cleanly in case of an
* abend.

* PROBLEM FIXED: GDDR-3499
* USERS AFFECTED: GDDR users
* PROBLEM DESCRIPTION: New PRIMARY command to display primary
* C-system name
*
* DESCRIPTION DETAIL:
*
* A new command is needed to display the primary C-system name
* from any system in the GDDR-plex, including managed systems.
*
* PROBLEM RESOLUTION:
*
* A new PRIMARY command has been created to display the
* primary C-system name from the point-of-view of one or more
* C-systems. By default, the point-of-view from all C-systems
* is shown. The SYSTEM parameter may be used to narrow the
* scope to the specified C-system, and the SITE parameter may
* be used to narrow the scope to the C-system at the specified
* site. This command may be issued from any system where
* GDDRMAIN is active, including managed systems. It can be
* issued as a GDDRMAIN modify command (e.g., F GDDRMAIN,PRI),
* as a Perform Health Check panel primary command (e.g., PRI),
* or using the GDDRMCMD batch interface (see GDDRMCMD in
* SAMPLIB).
*
* Syntax:
*
* PRImary
* [,SITE={DC1|DC2|DC3|DC4}]
* [,SYStem={<system_name>|LoCaL|ALL}]
* [,TiMeOut=<seconds>]
* [,CONsole[={Yes|No}]]
* [,SysMSG[={Yes|No}]]
* [,SysPRinT[={Yes|No}]]
* [,DeBuG[={Yes|No}]]
*
* Example:
*
* GDDUC04I Primary C-system as seen from the indicated
* site/system

*
* DESCRIPTION DETAIL:
*
* An S0E0-29 abend could occur upon GDDRMAIN startup in the
* HBM (heartbeat monitor) subtask at GDDREVMI offset 0005AF74
* (data at PSW 183158F0 0010D507 3000F154). This causes the

* heartbeat monitoring capabilities.
*
* In addition, an S0E0-28 abend could occur in GDDRRPT upon
* GDDRMAIN shutdown at GDDRMAIN offset 0006EAB2 (data at PSW
* D24FD37A 1000D207 D37D5004).
*
* PROBLEM RESOLUTION:
*
* An S0E0 abend should no longer occur upon GDDRMAIN startup
* in GDDREVMI or upon GDDRMAIN shutdown in GDDRRPT.
