Splitting pairs
1.
If you want the split S-VOLs to be identical to the P-VOLs, stop all write operations to the P-VOLs
before splitting the pairs. This ensures there are no updates to the P-VOLs while the pairsplit
operations are synchronizing the S-VOLs to the P-VOLs.
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 BC asynchronous update copy operations, this status
transition can take several minutes.
2.
In the BC main screen, select the port, host group, or P-VOL in the Tree View box to filter the
volumes displayed in the Volume list.
3.
Select the pairs you want to split, right-click the selected P-VOLs, and select Pairsplit. The Pairsplit
window appears. You cannot split a suspended (PSUE) pair.
4.
In the Pairsplit window, set the copy pace (Slower, Medium, or Faster) for all pairs being split.
If you change the setting, the latest setting is applied to all pairs
5.
Set the split type (Quick Split or Steady Split) for each pair 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.
6.
When the Pairsplit window displays the pairs you want, click OK to add all pairs to the Preset
Volume list on the BC main pane. Use the Delete command to remove any pairs from the list.
7.
In the BC main screen, click Apply to split the pairs.
When the pairsplit operations start, the BC main screen shows new pairs with COPY(SP) or
PSUS(SP) status and progress (%) of the update copy operations. The PSUS status is displayed
right away if there were no pending update copy operations
8.
Click Refresh ( ) to monitor the progress of the pairsplit operations.
Creating and splitting pairs
Use the pairsplit operation to simultaneously create and split new BC pairs. In this case, the pairsplit
operation changes the pair status from SMPL to COPY(SP) or PSUS(SP), copies all data on the P-VOL
to the S-VOL, and changes the pair status to PSUS.
1.
If you want the split S-VOLs to be identical to the P-VOLs, stop all write operations to the P-VOLs
before creating and splitting the pairs. This ensures there are no updates to the P-VOLs while the
pairsplit operations are synchronizing the S-VOLs to the P-VOLs.
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 BC asynchronous update copy operations, this status
transition can take several minutes.
2.
In the BC main screen, select the port, host group, or P-VOL in the Tree View box to filter the
volumes displayed in the Volume list.
3.
Select the volumes that will be the P-VOLs of the new pairs to be created and split, right-click the
selected P-VOLs, and select Pairsplit. The Pairsplit window appears.
