Starter set configuration considerations

z/OS DFSMShsm Implementation and Customization Guide
SC23-6869-01

Review the following considerations when configuring and implementing the DFSMShsm starter set:
  • Do not use the small-data-set-packing data set function, unless you have defined it on one or more level 1 migration volumes. See Defining migration level 1 volumes to DFSMShsm for more detail.
  • Do not define level 2 migration volumes. If you want to verify level 2 migration volumes, define them after you have the starter set running and after you have all other DFSMShsm functions running smoothly. ARCCMD91 is a sample job that initializes and identifies tapes (with the ADDVOL command) to DFSMShsm.
  • Run the starter set on one host defined as host number one. Because this is the only host running DFSMShsm, host number one is also defined as the primary host. See the HOST= keyword of the DFSMShsm-started procedure in Startup procedure keywords for more information.
  • Back up the control data sets to tape.
