The Compatible FlashCopy linkage configuration
Overview of functions
A configuration in which a Compatible FlashCopy S-VOL and a Continuous Access Synchronous
Z, TrueCopy Asynchronous for Mainframe, or Continuous Access Journal Z copy pair P-VOL are
the same volume can be concurrently used as shown in
Figure 30 (page 68)
When Compatible FlashCopy is linked, datasets created by using Compatible FlashCopy can be
remotely copied to the secondary site by using Continuous Access Synchronous Z, TrueCopy
Asynchronous for Mainframe, or Continuous Access Journal Z.
Figure 30 Example of a Compatible FlashCopy linkage configuration
Continuous Access Synchronous Z can be used to link with a Compatible FlashCopy pair that uses
the Preserve Mirror function as shown in
Figure 31 (page 68) .

Business Continuity Manager supports the following functions in a Compatible FlashCopy linkage
configuration:
•
The YKFCSTAT command can be used to determine the copy status in order to monitor the
completion of the copy processing for a linked Compatible FlashCopy.
•
During Preserve Mirror execution, the inconsistent status of a Continuous Access Synchronous
Z copy pair (the status in which the consistency of data on the P-VOL and the S-VOL cannot
be guaranteed) caused by an interruption to Compatible FlashCopy copy processing can be
obtained as the CONSLOST status.
For details about operations using these functions, see “Using Compatible FlashCopy linkage
configurations” (page 330) .
