Controlling Local Devices

This chapter tells you how to use z/VM® commands to control devices connected to your processor complex. After reading this chapter, you can control:
  • Channel paths to devices
  • Dynamic switching devices
  • Displays, 3270 printers, and communication lines
  • Systems network architecture (SNA/CCS) terminals
  • Direct access storage devices (DASDs)
  • Tape drives
  • Channel-to-channel adapters (CTCAs)
  • Printers and printer spool file queues
Note: z/VM also provides the ability to change the real I/O configuration. CHPIDS, CONTROL UNITS, and DEVICES can be added, deleted, and modified dynamically without an IPL or POR (Power® On Reset).
