Description
We are implementing CA Dynam/T control of VTAPE jobs on our z/VSE system. After setup, when we attempt to run a job, we get the error message
CADT106D- NO AVAILABLE VIRTUAL DRIVES FOR VTAPE PROCESSING. What is wrong?
Solution
As part of the VTAPE (IBM Virtual Tape Facility) support setup, as described in the CA Dynam for VSE 7.1 User Guide, a DTVIRT parameter is coded for Dynam/T. In this case the cuu device range was 7FD through 7FF. Unfortunately, this range overlapped the regular Dynam/T 'dummy' range (DTOPTIONS DUMMY=(7F0,7FF)). Once these ranges were changed so that they did not conflict, VTAPE jobs no longer failed.
See the product documentation for additional notes on these topics.
To use the automatic virtual tape support, a list of virtual CUUs must be defined to CA Dynam/T for use when mounting virtual volumes. The system option record DTVIRT was created for this purpose. It can be defined and maintained online using CUI, or in batch using program CACCDBU0. The CUUs defined must be added as cartridge devices in the VSE IPL procedures.
An example ADD statement would be: ADD CA2:CA4,3480. The CUUs must be in a DVCUP status. No real devices can use any of the defined virtual CUU addresses.
