This technique allows an IBM System/370XA operator to reset a single channel path, without causing any data integrity or performance problems due to devices being reserved to the specified channel path or devices having the specified channel path in a dynamic pathing group. A menu option is provided on the operator console of a machine operating in XA mode to allow the operator to designate the channel path identifier (CHPID) of a channel path that is to be reset. When a valid CHPID is entered, the program is presented with a new type of channel report word (CRW), "RCHP requested" CRW, for the designated channel path.
