Special Instructions

This is a PTF for Tape IOP licensed internal code.  To fully activate
it all the tape controllers and devices associated with the IOP must be
varied off, then VARY ON one of them with a RESET(*YES).
If it is not possible to vary on with the RESET(*YES) option,
you must IPL the system to activate this PTF.

To activate this PTF for an IOP
that will allow VARY ON with RESET(*YES):

1.  Vary off all tape controllers and tape devices attached to the IOP.
2.  Vary on one of the controllers or devices under the IOP using
For Controllers:
VRYCFG CFGOBJ(The controller) CFGTYPE(*CTL) RESET(*YES)

For Devices without Tape Controllers:
VRYCFG CFGOBJ(The device) CFGTYPE(*DEV) RESET(*YES)

and other parameters as would normally be done.
3.  Vary on all of the other controllers and devices normally.
