5. When the Pairsplit dialog box displays the desired pairs, click OK to reflect all pairs to the
Preview List on the Pair Operation window.
Use the Delete command selected from the menu (that displays by right-clicking) to remove
any pairs from the Pairsplit Volume List.
6. On the Pair Operation window, click Apply to apply the pairsplit operations set in the Pairsplit
dialog box to the storage system.
When the pairsplit operations start, the Pair Operation window shows the new pairs with
COPY(SP) or PSUS(SP) status and the progress (%) of the update copy operations. The PSUS
status is displayed right away if there were no pending update copy operations.
Performing Pair Creation and Pair Splitting
The Pairsplit dialog box can also be used to simultaneously create and split new XP Business Copy
pairs.
CAUTION: The P-VOL and S-VOL are synchronized only when the pair status changes from
COPY(SP) or PSUS(SP) to PSUS. Due to the XP Business Copy asynchronous update copy operations,
this status transition can take several minutes.
If you want the S-VOLs you are intending to split to be identical to the P-VOLs, stop all write
operations to the P-VOLs before creating and splitting the pairs. This ensures that there are no
updates to the P-VOLs while the pairsplit operations are synchronizing the S-VOLs to the P-VOLs.
1. Go to the Pair Operation window, and select the desired port or host group in the Tree to
filter the volumes displayed in the Volume List.
2. Select the SMPL volumes that will be the P-VOLs of the new pairs to be created and split,
right-click the selected P-VOLs to display the menu, and then select the Pairsplit command to
open the Pairsplit dialog box.
3. On the Pairsplit dialog box, select the copy pace from the Copy Pace list.
4. Select Quick Split or Steady Split from the Select Split Type list.
5. Specify the S-VOL that you want to form an L1 pair with each P-VOL by performing the following
the steps:
a.
From the Pairsplit Volume List, select the desired P-VOL.
b. From the Select MU list, select the MU number (0, 1, or 2) for the L1 pair to be created.
c. From the Port list in the Select S-VOL box, select the desired S-VOL port.
d. Select the Reserved check box in the Reserved box to make the reserved volumes appear
on the S-VOL List.
e. From the S-VOL List, select the volume you want to use as the S-VOL of the pair you are
creating.
You can also select the S-VOL from unreserved volumes, because once you select an
unreserved volume, the storage system will automatically set its reserve attribute and make
it a reserved volume.
f. Click Set.
The S-VOL displays next to the selected P-VOL in the Pairsplit Volume List.
g. To add and split another S-VOL to and from the same P-VOL, repeat steps b through f .
Each pair to be created and split displays separately in the Volume List.
You cannot select the same MU number for different pairs.
6. Repeat step 5 until the desired L1 pairs are displayed.
Use the Change button to replace S-VOLs, the Set button to add L1 S-VOLs, and the Delete
command in the menu to remove pairs from the Pairsplit Volume List.
