Issue/Introduction

Determining the number of output tapes that MERGE uses, before the Disk MERGE job starts.

Environment

Release: Disk™ Backup and Restore

Resolution

You can run MERGE SIMULATE to help determine how many output tapes would be needed by specifying a special value for the output device capacity.

Example: If you are using the DYN1 path (sysparm MERP1TYP set to DYN1) then specify the special simulate value that relates to your tape capacity with the DYN1UNIT sysparm. (If DYN2 then specify DYN2UNIT etc.)

Refer the Disk tech guide for DYNCUNIT in the "System Parameter Definitions" for the documented simulate values in entry "DYNnUNIT".
