Issue/Introduction

What is the difference with the Copycat MERGE option? I just want to copy a series of tapes to a new series.

Environment

CA Copycat - CA TLMS and CA-1.

Resolution

By default, the MERGE option is set to YES. If the goal is to copy a volume series to another media type, you need to use the MERGE=NO option. With this option, you are making an identical copy of the input volume to a new output volume(s).

 

Example 1). A new VTS system is coming in and you need to copy all of the volumes from the old VTS to the new VTS.

 

With MERGE=NO

Volsers 100000 and 100001 are the inputs.

Volsers 20000 and 200001 were used for output.

All data and chaining will be copied from the input volumes and re-cataloged to the 200000 and 200001 volumes.

With MERGE=YES

Volsers 100000 and 100001 are the inputs.

Volser 200000 will have the data from volser 100000 and 100001. Volser 200000 will have 2 files, one from volser 100000 and 100001. You would not want to use the MERGE=YES to make identical copies.

Options to be aware of:

RECATLG= . You can use RECATLG or ALL for this. RECATLG=ALL will un-catalog the input and catalog the new output volumes. RECATLG=PREV will catalog the output IF the input was cataloged.

OUTDISP= . Assign the same retention on the output file that was on the input file.
