IRD003I

Explanation
A VARY command was issued for a switch device. The device support
code attempted to validate that the channel path type was compatible
with the switch type.
In the message text: switch_type
The type of switch; for example, ESCON®, FICON®.
cc
The channel path type found for the switch device. Descriptions
of all the supported channel path types can be displayed by using
the D M=CHP command.
channel_path_type
If provided, the channel path type found.

System action
The VARY command fails. If VARY ddd,ONLINE was issued, the devices
remain offline. If VARY PATH(dddd,cc),ONLINE was issued, the device
path remains offline.

Operator response
Make sure that the operating system and channel subsystem are using
the correct I/O configuration definition.  DISPLAY IOS,CONFIG displays
the currently active IODF (I/O definition file) and currently active
I/O configuration for the channel subsystem.  The MVS™ ACTIVATE command can be used to dynamically switch
to the correct I/O configuration definition.  Then the VARY command
should be retried.

System programmer response
Correct the configuration error and retry the VARY command.  Configuration
errors can be corrected dynamically by updating the I/O configuration
definition with the HCD (hardware configuration definition) and issuing
the MVS ACTIVATE command.
