•
If the P-VOL is already paired with other S-VOLs (“PAIR” status), you have determined that the
status of existing S-VOLs is in the status that is required to create the new pair.
For more information about S-VOL status, see “Unaffected S-VOL status and pair user tasks”
(page 67) .

If you are concerned with host server I/O performance, you have determined that the I/O
load is light.
For more information about checking I/O performance-related information, see the HP XP7
Remote Web Console User Guide.
Creating BC pairs
Creating an BC pair copies the P-VOL to the S-VOL.
If the DKA you use supports encryption, you can create an BC pair from an encrypted volume and
an unencrypted volume, but keep in mind that if encrypted data is copied to the unencrypted
volume, it becomes unencrypted.
NOTE: If you are using RAID Manager to run commands and run the following command to
create the pair, the data is backed up data and all existing data on the S-VOLs is overwritten:
Paircreate
For more information about this command, see the HP XP7 RAID Manager User Guide.
NOTE: If you create an BC/SS pair during WriteSame or Unmap command processing, the pair
creation might fail. In this case, create the pair again after the WriteSame or Unmap command
processing finishes.
1. In the RWC main window, in the resource tree, click Replications > Local Replication > BC
Pairs.
2. In the BC Pairs tab, click Create Pairs.
