Channel Wrap Test (FICON)
A channel wrap test is a diagnostic procedure that checks FICON host-to-director
link connectivity by returning the output of the host as input. The test is host
initiated, and transmits ECHO extended link service (ELS) command frames to a
director port enabled for channel wrapping. The director port echoes the frames
back to the host.
To perform a channel wrap test for a director-attached host:
1. Notify the customer a disruptive channel wrap test will be performed on the
host-to-director FICON link.
