CMUC00160W rmpprc: Are you sure you want to delete the Remote Mirror and Copy volume pair 
relationship 1600:1600:? [y/n]:y
CMUC00155I rmpprc: Remote Mirror and Copy volume pair 1600:1600 relationship successfully 
withdrawn.

You can suppress the CMUC00160W confirmation message by adding the 

 

parameter.

With the 

 command, you can 

 an existing Consistency Group; see 

Example 20-23. It resumes host application I/O activity for primary volumes on the 
Consistency Group that was created by an earlier 

 command. 

The 

 command is used to reset the extended long busy condition for the primary 

volume and release application I/O to the primary volumes. All queued writes to the source 
volume are written. The status of the volumes does not change; the primary volumes remain 
in the suspended state as set by the 

 command.

The DS Storage Manager (DS SM) is a graphical user interface (GUI) that can be used to set 
up and control Global Copy. It is user friendly, however, you cannot use it for automation 
activities, and certain remote mirror and copy functions are not supported from this interface.

In this section we give examples of common tasks that are performed using the DS SM.

The Path panel is the central point in the DS Storage Manager to establish new paths and 
manage existing paths. You can get to the path panel as follows:

1. Select 

Real-time manager.

2. Select 

Copy Services.

3. Click 

Paths. 

Then the Paths panel will display; see Figure 20-1 on page 234. Here, to display existing 
paths, select the storage unit and the LSS for which you want to display the paths information.

Note: Because the 

 command deletes the paths between the specified LSS 

pair, you have to reestablish them to resume normal Global Copy operation.
