These channel paths are named as members of path groups. Each path group has one or more channel paths. Within each path group, communications between the data-processing system and the peripheral system are multipathed among the paths in such path groups. Devices within the peripheral system are selectively assignable to access groups for exclusive use within one or more of such path groups; a given path group selectively provides communication paths for each device in an access group. Each access group includes one or more path groups. Temporary suspension and reassignment facilities are disclosed. Both devices and channel paths can be either in a grouped or ungrouped state. The assignment function to access groups is particularly useful in interleaved channel transfers for ensuring subsystem integrity. | |
