ABSTRACT OF THE DISCLOSURE A peripheral subsystem accepts and responds to a plurality of supervisory channel commands which alter the operation of the subsystem; i.e., logically partition, break the logical partition, adjust or amend the logical partition, ignore the logical partition, give operator controls for loading and unloading a record cartridge, suspending multi- path reconnection and the like. These supervisory commands can be located anywhere in a I/0 chaining sequence. Some of the supervisory commands will result in changes in the subsystem operation for the duration of the instant channel program or CCW chain while other persist for as long as the sub- system is operating or until a subsequent super- visory command overrides the previous supervisory command. One of the supervisory commands can selectively inhibit subsequent supervisory commands only within a given I/O chain. This selective inhibit provides subsystem integrity. At the end of the chain, the inhibition is removed.
