Symptoms

When issuing the "QUERY SNAPSHOT" command against a device which contains zDP snapshots that were created in an environment running PowerMaxOS 5978.300 and higher, ABENDS0C4-3B may occur during snapshot sorting.

Example:

PROCESSING FOR STATEMENT #2 BEGINNING, QUERY SNAPSHOT FOR VOLUME *4F00*
PROCESSING CONTROLLER S/N nnnnnnn-nnnnn - MICROCODE LEVEL - 5978
ABEND OCCURRED: S0C4 PSW: 078D30019538F364
PROCESSING COMPLETED, HIGHEST RETURN CODE ENCOUNTERED IS 99

 

Cause

Software passed incorrect data in the high area of GPR1 to ECNQSORT resulting in an S0C4-3B abend.

 

Resolution

Permanent Fix:

  • For Mainframe Enablers 8.5, PTF SN85050 has been developed to correct the issue. It is available to download from Dell Technologies Online Support.
  • For Mainframe Enablers 8.4, PTF SN84083 has been developed to correct the issue. It is available to download from Dell Technologies Online Support.

 

Additional Information

QUERY SNAPSHOT
Displays snapshots for the specified source device and their relationship to target devices
To specify a range of devices, use the DEVICE option with the LOCAL or REMOTE parameter.

Note: To view detailed information about the snapshot devices, run the "QUERY VOLUME" command that is described in the TimeFinder/Clone Mainframe Snap Facility Product Guide.

Multiline query
When MULTI_LINE_query(YES) is specified, properties of each snapshot are displayed, such as:

  • Snapshot ID
  • Track statistics
  • Time since creation and Time to Live
  • Whether the snapshot is secure

When COMPACT_query(YES) is specified, status fields are displayed at the end of each line to provide a single-line summary of important snapshot information, including:

  • Snapshot status and whether the snapshot has been activated.
  • Link type (softlink, hardlink)
  • Snapshot copy mode (COPY or NOCOPY) and status (if every track on the source has been copied to the target at least one time).
  • Whether the snapshot is secure and (or) zDP-managed.
