Business Continuity Manager specifications
Pair operations may be performed using Business Continuity Manager (BCM) commands from the
host system to the storage system. With BCM commands, you can add, split, resynchronize, and
delete pairs, and monitor pair status. You can also create the Continuous Access Synchronous Z
association between primary and secondary system (add RCU).
•
For the correspondence between the LINK parameters (ports) and SAID values, see “SAID
values for CESTPATH/YKBLDPTH” (page 19) .
•
For corresponding PPRC functionality, see “PPRC, BCM command comparison” (page 18) .
•
Although the same Continuous Access Synchronous Z pair operations may be performed by
using Business Continuity Manager or PPRC, Business Continuity Manager and PPRC are
independent functions. Do not use Business Continuity Manager and PPRC for the same pair
operation.
For complete information, see the Business Continuity Manager User's Guide.

Not all Continuous Access Synchronous Z operation options are supported by Business Continuity
