The Delete Pair dialog box (see Figure 6-7) allows you to release one or more
TCz pairs and select the release options for the pair(s). To open the Delete
Pair dialog box, click the Pair Operation tab, select a CU grouping or CU from
the tree, select the desired pair(s), right-click, and then click Delete Pair
command.
Figure 6-7 Delete Pair Dialog Box (Asynchronous)
Note: If you select a pair from the volume list and change the settings, and if
you use a drop-down list to set blank to a parameter, the parameter takes the
default value for each pair. If you select the settings from the preview list
before applying the changed settings, and if you use a drop-down list to set
blank to a parameter in the Delete Pair dialog box, the parameter value in
the preview list will not be changed.
Volume: the device ID of the selected volume. If you selected more than one
volume, the volume with the lowest device ID is displayed.
Note: If "#" is added to the end of the device ID like 00:00:3F#, the LDEV
that the LDEV number indicates is an external volume. For details on an
external volume, please refer to the Universal Volume Manager User's Guide.
Deleting Mode:
• Normal: performs a normal release pair operation for the selected pair(s).
The pair(s) will only be released if the MCU is able to change the pair status
of the M-VOL and R-VOL to Simplex.
• All: allows you to release all TCz Synchronous pairs with the same MCU and
RCU (same CU) as the selected pair. This option can be selected from the
MCU or RCU. This option releases the pairs more quickly than if you select all
pairs on the TCz windows and release them.
