8.85 LEGACYSENSEID (Display or set SENSE ID CCW (x'E4') feature)
8.85.1 Function
The LEGACYSENSEID command specifies whether the SENSE ID CCW (X'E4') will be honoured for the
devices that originally did not support that feature. This includes (but may not be limited to) 3410 and
3420 tape drives, 2311 and 2314 direct access storage devices and 2703 communication controllers.
Because those legacy devices didn't originally support this command, and for compatibility reasons, the
default is OFF or DISABLE.
Specify ON or ENABLE, if your guest operating system needs the Sense ID support to dynamically detect
those devices. Note that most current operating systems will not detect those devices even though Sense
ID is enabled because those devices never supported the Sense ID in the first place. This mainly applies
to custom built or modified versions of guest operating systems that are aware of this specific Hercules
capability.
Given without an argument the LEGACYSENSEID command displays the current setting.
