Symptoms
Programvaren for stormaskinoperativsystemet oppdateres til z/OS 2.5-programvarenivå med vedlikeholdstoleranse. z/OS 2.5 brukes til en ny IBM z16 CPU.
GDDR GDDRMAIN startet opp med flere ABENDer etter at z/OS-vedlikeholdet ble tatt i bruk:
- HBM rapporterer feilen nedenfor ved GDDRMAIN-oppstart, GDDR-verten er i degradert modus:
ABEND S0E0-29
- GDDRRPT rapporterer feilen nedenfor ved GDDRMAIN-avslutning:
ABEND S0E0-28
Følgende feilmeldingsinnlegg i GDDR Event Monitor (EVM) og Heartbeat Monitor (HBM)-utdata:
GDDUG86E No matching GDDR systems found
Hvis ABEND S0E0-28 skjer ved GDDRMAIN-avslutning, og deretter en Abend S067-04 kan oppstå hvis GDDRMAIN hentes opp igjen.
Cause
En
I tillegg har en
ABEND S0E0-29 kan oppstå ved oppstart av GDDRMAIN i HBM-deloppgaven ved modul GDDREVMI, offset 0005AF74.
PSW 183158F0 0010D507 3000F154Dette fører til at HBM-deloppgaven avsluttes og forlater GDDRMAIN uten funksjoner for hjerterytmeovervåking. GDDR-verten kjører i degradert modus. GDDREVMI oppdateres for å tømme REGISTER AR15 før du bruker registeret for å unngå en
ABEND S0E0-29.
I tillegg har en
ABEND S0E0-28 kan forekomme i GDDRRPT ved GDDRMAIN-avslutning ved GDDRMAIN, kompensasjon 0006EAB2.
PSW D24FD37A 1000D207 D37D5004GDDRRPT oppdateres for å tømme REGISTRER AR1 for å unngå en
ABEND S0E0-28. GDDRMAIN oppdateres for å bekrefte at dataområdet 2 Access List Entry Token (ALET) er gyldig. Denne handlingen utføres før du åpner dataområdet for en annen GDDR-forekomst. Denne handlingen bidrar til å unngå en Abend S067-04 i GDDRMAIN-oppstarten på grunn av at en annen GDDR-forekomst ikke avsluttes rent.Resolution
Omgåelse av problemet:
- Ingen for ABEND S0E0-29, men GDDR-vertene fortsetter å kjøre i degradert modus.
- En initial programbelastning (IPL) av den logiske partisjonen (LPAR) kreves for å tømme minnet hvis en
Abend S067-04Oppstår.
Permanent korrigering:
- For GDDR 6.0 er GD60004 og GD60005 for midlertidig programreparasjon (PTF) tilgjengelig for nedlasting fra Dell Support.
- For GDDR 6.1 er problemet løst i basisproduktet. Den er tilgjengelig for nedlasting 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.

* 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
* HBM subtask to terminate and leaves GDDRMAIN without
* 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.
