UID (default = HSM)

Specifies the DFSMShsm authorized-user identification (UID) in 1 to 7 characters. You must use this UID as the first qualifier of the data set name of the SDSP data sets. In the DFSMShsm starter set sample jobs (see DFSMShsm starter set), the UID is the prefix name for the migrated and backed up data sets. The UID is also the first qualifier of the DFSMShsm log in the DFSMShsm started procedure in topic Starter set example. For the starter set, HSM is the UID.

Note: Changing the UID parameter after your environment has been set up requires coordination, because DFSMShsm expects the UID to be the high-level qualifier for SDSP data sets. If you change the UID, you must also change the high-level qualifier of existing SDSP data sets to match the new UID. Although the UID also appears as the high-level qualifier of tape data sets, DFSMSrmm and most other tape management systems allow the high-level qualifier to be different.
