Operational differences for replication commands
The following table shows the differences between open volumes and mainframe volumes in
replication commands. For details on the differences, see the manual for each program product.

You cannot specify this
option in Business Copy or

*If the capacity of the S-VOL is larger than that of the P-VOL, you cannot create a pair with RAID Manager. To create
a Continuous Access Synchronous Z pair with volumes that differ in capacity, use Business Continuity Manager or
Remote Web Console.
Notes:
•
A mainframe primary volume may also be called a source volume or a main volume.
• A mainframe secondary volume may also be called a target volume or a remote volume.
