User’s Guide
– CTG: Displays the ID of the CTGs selected in the CTG Tree by attribute
or by Subsystem on the top of the tree. Note that the consistency
groups that you can display on the CTG window are only those reserved
in a mainframe storage system.
– Group Status: Displays the status of the selected CTGs displayed with
an ID. If the status of the CTG has been changed due to operations
performed earlier, the latest status will be displayed. In case a CTG
operation could not be applied successfully to the USP V storage system
after clicking the Apply button, the data of the CTG before the
operation has been applied to the USP V storage system is displayed.
The status of the CTGs displayed here will be one of the following three:
• Used: Status indicating that the consistency group is used.
• Reserved: Status indicating that the consistency group is reserved.
• Free: Status indicating that the consistency group is not used.
– Code: Displays the error code when a CTG operation fails to be applied
to the USP V storage system.
• The Apply button applies the SIz operations displayed in the CTG List to
the USP V storage system.
• The Cancel button cancels all the ongoing operations specified in the CTG
List without applying them to the USP V storage system.
To perform a CTG operation, use the desired command selected from the pop-
up menu that can be displayed by right-clicking one of the CTGs displayed in
the CTG List that you want to work on. Table 4-5 shows the available pop-up
menu commands in the CTG List.
