Quick Split and Steady Split in the Pairsplit dialog box. However, you need RAID Manager to
perform At-Time Split.
•
Pairsplit by Quick Split:
When you specify Quick Split, the pair status changes to PSUS(SP). The S-VOL is available
immediately for read and write I/Os (even though it is still reserved). The entire P-VOL data
or differential data will be copied to the S-VOL in the background.
•
Pairsplit by Steady Split:
When you specify Steady Split, the pair status changes to COPY(SP), and the whole P-VOL
data or differential data at that time will be copied to the S-VOL. When the Steady Split
operation is complete, you have full read/write access to the split S-VOL (even though it is
still reserved). To quickly complete the copy operation to access the S-VOL, make the P-VOL
offline before the operation.
•
Pairsplit by At-Time Split:
Pairsplit operation by At-Time Split can be performed by using RAID Manager.
When the XP Business Copy At-Time Split function is enabled, data in all P-VOLs in the same
consistency group is created in the corresponding S-VOLs when the storage system receives
the pairsplit request from the host server.
Figure 5 (page 14) shows an overview of the XP
Business Copy At-Time Split function.

Consistency groups are defined by RAID Manager’s configuration definition file, which is
created by users. The XP Business Copy software on the Remote Web Console computer
displays consistency group information, however, you cannot perform the At-Time Split operation
by using Remote Web Console. Use RAID Manager from the host to perform the At-Time Split
