the Display Filter as needed to display the desired LVIs (for example, select Simplex status
only).
4.
Select the LVI(s) which will be the M-VOL(s) of the new TrueCopy for Mainframe pair(s). You
can create multiple pairs at the same time only when: (1) the R-VOLs are in the same RCU,
and (2) the pairs have the same copy mode (sync or async). You cannot create TrueCopy for
Mainframe Sync pairs and TrueCopy for Mainframe Async pairs at the same time.
5.
Right-click, click Add Pair, and then select the desired pair mode (Synchronous or Asynchronous)
to open the Add Pair dialog box (see
“Add Pair Dialog Box for Synchronous Pairs” (page 144)
and
“Add Pair Dialog Box for Asynchronous Pairs” (page 145)
).
The update copy mode, sync or async, has the greatest impact on performance and must be
considered carefully. Factors in mode selection include (but are not limited to) the use of
TrueCopy for Mainframe (for disaster recovery or migration), the number of pairs, and the
write I/O activity to the M-VOLs.
6.
On the Add Pair dialog box, enter the desired R-VOL for the pair, and select the RCU. If you
are creating multiple pairs, select the R-VOL for the M-VOL being displayed. The R-VOLs for
the rest of the M-VOLs will be assigned automatically according to the LDEV ID. For example,
if you select three M-VOLs and select device 01 as the R-VOL for the first M-VOL, the R-VOLs
for the two other M-VOLs will be device 02 and device 03.
7.
Select the desired initial copy options and pair options. The initial copy options and pair
options you select are applied to all pairs being created, and you can modify the options for
each pair as needed before starting the add pair operations (see step 9).
8.
Click Set to close the Add Pair dialog box. The requested add pair operation(s) is/are now
displayed in the preview list.
9.
Verify the requested operation(s) displayed in the preview list. Make sure that all options for
each new pair are correct. After a pair has been created, you can only change the M-VOL
fence level, CFW data, and error level options.
To change one or more operation(s), 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 Cancel.
To set the parameters on the multiple volumes at once without changing individual parameters
per volume, make the box of parameters that you do not want to change blank. Only the
parameters that you input will be changed.
10.
To start the operation(s), click Apply.
The MCU will start the initial copy operations according to the initial copy priority and the
maximum initial copy activities setting on the System Option window.
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 to close the error message.
11.
On the Pair Operation window, verify that the add pair operation(s) is/are displayed correctly
(Pending status) in the list. To monitor the progress of the add pair operation(s), click File, and
then Refresh on the menu bar of the Remote Web Console main window to update the
information in the list, or use the Detailed Information dialog box to monitor the detailed status
of each pair.
If an error occurs after you click Apply, you can display the error message by right-clicking on the
operation and clicking the Error Detail command.
The add pair operation will be rejected if the M-VOL is in the correction access or correction copy
state. If this occurs, wait for the volume state to change, and then repeat this procedure. If the status
is not displaying correctly, make sure that the correct CU is selected.
