Issue/Introduction

Are there any considerations moving the TMC to a SMS managed DASD volume?

Environment

Release : 14.0

Component : CA 1 Tape Management

Resolution

CA 1 does not care if the TMC is on SMS or NON SMS managed DASD. If the TMC is allocated on SMS managed DASD, then it is no longer possible to allocate it with DSORG=PSU, which we recommned, to prevent the TMC from being migrated erroneously. Instead of DSORG=PSU start the optional CTS address space, which allocates TMC and AUDIT, to prevent invalid migration.
