Making Devices unavailable to the System

Making a display, 3270 printer, or communication line unavailable to the system is the opposite of making it available. p: To make it unavailable to the system:

1. Make sure it is not in use. Enter a QUERY command for the device to find out if it is.

   If the status indicates that a user is logged on the display or communication line or is using the 3270 printer, follow the procedure at Removing Devices from User Access. The status should read DISABLED before you go to the next step.

   If the status indicates that it is dedicated to the production system, follow the procedure at Removing These Devices from the Production System. The status should read DISABLED before you go to the next step.

2. Enter:

   vary offline rdev

   where rdev is the real device number of the device. The display, 3270 printer, or communication line is now unavailable to z/VM®.
