Performing Only Pair Splitting
CAUTION:
If you want the T-VOLs you are intending to split to be identical to the S-VOLs, stop
all write operations to the S-VOLs before splitting the pairs. This ensures that there are no updates
to the S-VOLs while the split operations are synchronizing the T-VOLs to the S-VOLs.
The S-VOL and T-VOL are synchronized only when the pair status changes from SP-Pend or V-Split
to Split. Due to the SIz asynchronous update copy operations, this status transition can take several
minutes.
To split one or more existing SIz pairs:
1.
Go to the Pair Operation window, and select the desired CU image or S-VOL in the Tree to
filter the volumes displayed in the Volume List.
2.
Select and right-click the pairs you want to split (other than the suspended pairs) to display
the menu, and then select the Split Pair command to open the Split Volume Pair dialog box.
3.
On the Split Volume Pair dialog box, select from the Copy Pace list, the copy pace for all pairs
being split.
The copy pace is set for all pairs being split. If you change the setting, the last setting will
become effective.
4.
Select from the Select Split Type list, the split type for all pairs being split.
The split type is set for all pairs being split. If you change the setting, the latest setting is applied
to all pairs.
5.
When the Split Volume Pair dialog box displays the desired pairs, click OK to reflect all pairs
to the Preview List in the Pair Operation window.
Use the Delete command selected from the menu (that will be displayed by right-clicking) to
remove any pairs from the Split Volume Pair Volume List.
6.
In the Pair Operation window, click Apply to apply the Split Volume Pair operations set in the
Split Volume Pair dialog box to the storage system.
When the Split Volume Pair operations start, the Pair Operation window shows the new pairs
with SP-Pend or V-Split status and the progress (%) of the update copy operations. The Split
status displays immediately if there were no pending update copy operations.
Performing Pair Addition and Pair Splitting
The Split Volume Pair dialog box can also be used to simultaneously add and split new SIz pairs.
CAUTION:
If you want the T-VOLs, you are intending the split to be identical to the S-VOLs, stop
all write operations to the S-VOLs before splitting the pairs. This ensures that there are no updates
to the S-VOLs while the split operations are synchronizing the T-VOLs to the S-VOLs.
The S-VOL and T-VOL are synchronized only when the pair status changes from SP-Pend or V-Split
to Split. Due to the SIz asynchronous update copy operations, this status transition can take several
minutes.
To simultaneously add and split one or more new SIz pairs:
1.
Go to the Pair Operation window, and select the desired CU image or S-VOL in the Tree to
filter the pairs displayed in the Volume List.
2.
Select the Simplex volumes that will be the S-VOLs of the new pairs to be added and split,
right-click the selected S-VOLs to display the menu, and then select the Split Pair command to
open the Split Volume Pair dialog box.
3.
On the Split Volume Pair dialog box, select the copy pace from the Copy Pace list.
4.
Select the split type for all pairs being added and split from the Select Split Type list.
5.
Specify the T-VOLs you want to pair up with each S-VOL by following the steps below:
