*Note: If you plan to use the C/T Delete Range option, you must connect
to the RCU.
3. In the tree, select the CU or the upper CU grouping which contains the pair(s)
to be released. Use the Display Filter as needed to display the desired pairs
(e.g., select Async only).
4. In the list, select the pair(s) that you want to release. Select either TrueCopy
for z/OS Sync or Async pairs (not both). If you plan to use the TCz
Synchronous All Deleting Mode option, select only one TCz Sync pair. If you
plan to use the C/T or Group delete range option, select only one TCz Async
pair in the group.
5. Right-click, and click Delete Pair to open the Delete Pair dialog box (refer to
Figure 6-7).
6. On the Delete Pair dialog box, select the desired release options, and click
Set to close the dialog box. The preview list displays the requested release
pair operation(s).
7. Verify the requested operation(s) in the preview list. Make sure that the
release options for each pair are correct. The selected volume is listed first
(CU, Device, S/N, SSID), and the other volume in the pair is listed second
(CU, Device).
To change one or more operations, select the operation(s) from the
preview list, right-click, and click Modify. To remove one or more
operations, select the operation(s) from the preview list, right-click, and
click Delete. To cancel all operations, select all the operations in the
preview list, right-click, and click the Delete command or click the Cancel
button.
8. To start the operation(s), click Apply.
If one or more operation(s) did not start normally, the preview list displays
only the operation(s) that did not start normally. An error code is displayed
on the Error Code column in the preview list. To display an error message,
select one LU, right-click, and click Error Detail. After you see the error
message, click OK button to close the error message.
9. On the Pair Operation window, verify that the release pair operation(s)
is/are completed successfully (Simplex or Deleting then Simplex status, not
Suspend). To monitor the progress of the operation(s), click Refresh to
update the information in the list, or use the Detailed Information dialog box
to monitor the detailed status of each pair. You can also monitor the host
console messages (IEA494I vs. IEA491E) to verify the operation(s).
Note: To restart a pair which was released from the RCU, first release the pair
from the MCU, and then restart the pair using the appropriate initial copy
option (Entire Volume or None).
