VM:Tape's VMTDLMUT utility.
VM:Tape r2.0 PTF RO94878 introduced a new VM:Tape utility that can be used to change the status of a tape volume in the EMC Disk Library for Mainframe (DLM) database.
The utility is a stand alone module called VMTDLMUT.
Use the VMTDLMUT utility to change the status of a volume in the EMC Disk Library for Mainframe (DLM) database.
The VMTDLMUT utility changes the status of a single volume per execution; for example, to change the DLM database status of the specified volume to a status of SCRATCH.
The VMTDLMUT utility requires that the CA VM:Tape server is running, and verifies the following conditions:
The VMTDLMUT utility logs all transactions that are executed (not aborted due to one of the previously listed conditions) to the file named DLMLOG LISTING on the CMS minidisk or SFS directory accessed at filemode A. If the file does not exist, it is created. If the file already exists, then it is appended to.
For complete VMTDLMUT utility information and usage, see the CA VM:Tape for z/VM - 2.0 Utility Reference page for the VMTDLMUT Utility which can be accessed here:
