Abstract: This presentation illustrates a typical HCD setup for zOS to be used when installing a TS7740 or TS7720 Subsystem. I have updated for 1.6 (4-Way) and added a spread sheet for calculating Logical Paths consumed. This sheet was designed and built by the noted Tape Specialist, Toy Phouybanhdyt.
