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.

 
D IOS,CUGRP[,ID=groupid       ]
           [,DETAIL           ]
           [,L={a|name|name-a}]

IOS,CUGRP: Displays information about one or more IOS control unit groups.
ID=groupid: Displays information about a specific control unit group. groupid specifies the control unit group identifier, which consists of three or four hexadecimal digits. If ID=groupid is not specified, information about all control unit groups is displayed.
DETAIL: Displays detailed information about the control unit group, which includes the list of control units.
L=a, name, or name-a: Specifies the display area (a), console name (name), or both (name-a) where the display is to appear.
If you omit this operand, the display is presented in the first available display area or the message area of the console through which you enter the command.

Example 1:

To display a summary of the control unit groups, enter:
