Displaying IOS control unit group information
Use the DISPLAY IOS,CUGRP command to display the information about one or more IOS control unit groups. A control unit group consists of one or more control units that share the same set of static CHPIDs. Each control unit group is assigned a group identifier that is the same as the lowest numbered control unit in the group. When dynamic channel-path management (DCM) makes a change, it makes a change to all managed control units in a control unit group at the same time.
