Setting status for a volume in a system-managed tape library

DFSMSrmm maintains volume status in the TCDB for volumes that are defined in the DFSMSrmm control data set. The status is updated using the RMM TSO commands or when volumes are released. Use the DFSMSrmm EDGRMMxx parmlib OPTION command SMSTAPE operand to control when the TCDB is updated. If the TCDB is not updated, the request to initialize or erase a volume in a system-managed tape library might fail because the volume is in a scratch library category. If DFSMSrmm is still running in record-only mode, use the AMS ALTER VOLUMEENTRY command to change the volume status. If DFSMSrmm is running in any other mode, you can use the RMM TSO commands to correct the volume status.

To set the correct status for the volume, issue two commands. Issue this command to complete the failed request.

RMM CHANGEVOLUME A12345 CONFIRMRELEASE(INIT)

Then issue this command to request that the volume be initialized.

RMM CHANGEVOLUME A12345 INIT(Y)
