Host Completion Message - IBM TS7700 Series User Manual

Host Completion Message

At the completion of the copy export operation, a completion message is broadcast to all hosts attached to
the TS7700. For z/OS, console messages are generated that provide information about the overall execution
status of the operation. There are different messages depending on what the TS7700 encountered during the
execution of the operation.
• If no errors or exceptions were encountered during the operation, message CBR3855I is generated. The
message has the following format:
CBR3855I Export operation for logical list volume volser in library
library-name completed successfully. Requested: requested-number
Exportable: exportable-number Exported: exported-number Stacked
volumes: stacked-number MBytes Exported: MBytes-exported MBytes Moved:
MBytes-moved
• If error or exceptions were encountered during the operation, message CBR3856I is generated. The
message has the following format:
CBR3856I Export operation for logical list volume volser in library
library-name completed with exceptions or errors. Requested:
requested-number Exportable: exportable-number Exported: exported-
number Stacked volumes: stacked-number MBytes Exported: MBytes-
exported MBytes Moved: MBytes-moved
If message CBR3856I is generated, you will need to examine the Export Status file to determine what
errors or exceptions were encountered. See the section on Export Status File Records.
Either of the above completion messages provides statistics on what was processed during the operation.
The statistics reported are as follows:
Requested-number: The number of logical volumes associated with the secondary volume pool specified
in the export list file. Logical volumes associated with the specified secondary volume pool that were
previously exported are not considered part of this count.
Exportable-number: The number of logical volumes that are considered exportable. A logical volume is
exportable if it is associated with the secondary volume pool specified in the export list file, it has a valid
copy resident on the TS7700 performing the export. Logical volumes associated with the specified
secondary volume pool that were previously exported are not considered to be resident in the TS7700.
Exported-number: The number of logical volumes that were successfully exported.
Stacked-number: The number of physical volumes that were successfully exported.
MBytes Exported: Number of Mbytes contained in the logical volumes that were successfully exported. If
the data on the logical volumes is compressed, the number includes the effect of compression.
Note: The number of Mbytes exported is the sum of the Mbyte integer values of the data stored on each
Exported Stacked Volume. The Mbyte integer value for each Exported Stacked Volume is the full count
by byte divided by 1,048,576 bytes/Mbyte. If the result is less than 1, the Mbyte integer becomes 1, and if
greater than 1 Mbyte, the result is truncated to the integer value (rounded down).
MBytes Moved: For copy export at code release level R1.3, this field reports the same number as the
MBytes Exported field. For copy export at code release level R1.4 and higher, this value is 0.
