Figure 6 Overview of Automatic Operations from BCM Monitor
For the BCM Monitor, you can use all the functions in the XP and P9000 storage systems that
Business Continuity Manager supports. However, 4x4x4 configurations are not supported.
Business Continuity Manager also provides the following functions.
Disaster Recovery Functions
• Reverse Resync function
This applies the S-VOL contents to the P-VOL, and changes the copy direction. This function
can be used to decrease the amount of time required for restoring operations after a planned
outage in 2DC configurations. In 3DC configurations, this function can be used to decrease
the amount of time required for failover or failback.
• Continuous Access Synchronous for Mainframe Consistency Preservation function
This preserves Continuous Access Synchronous for Mainframe copy group consistency, even
during planned stoppage due to maintenance, or failure.
• Delta Resync Function
If the host on the primary site has stopped, this function quickly changes the configuration to
a 3DC Multi-Target configuration in which the local site becomes the base for continuing
operation.
Operational testing function
This allows a suspended S-VOL to be updated, reducing the load required for reverting the
suspended S-VOL to its original status after testing is completed.
Functions that Support Copy Group Definitions and Operations
• Copy Group Configuration Check function - Verifies that the copy group definition and the
actual copy pair configuration match.
• FlashCopy Linkage function - Obtains the copy status of operations performed by the
Compatible FlashCopy function on the XP and P9000 storage systems.
