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, suspend, resynchronize,
and delete pairs, and monitor pair status. You can also create the Cnt Ac-S Z association between
main and remote 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 Cnt Ac-S 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 Cnt Ac-S Z operation options are supported by Business Continuity Manager. The following
