When the Preserve Mirror function is used and Compatible FlashCopy is interrupted

The Preserve Mirror function does not synchronize Compatible FlashCopy operations at the primary
site and the secondary site. Therefore, if Compatible FlashCopy operation is interrupted at the
primary site or secondary site, data on the P-VOL and S-VOL of the Cnt Ac-S Z copy pair linked
with the Compatible FlashCopy S-VOL might become inconsistent. Business Continuity Manager
is able to obtain this status (the status in which the consistency of data on the P-VOL and the S-VOL
cannot be guaranteed) as the CONSLOST status. If the Cnt Ac-S Z copy pair is placed in the
CONSLOST

status, you need to dissolve the copy pair, and then create it again.

The following describes the procedure for recovering a Cnt Ac-S Z copy pair from the CONSLOST
status.
1.

Execute the YKQUERY command for the Cnt Ac-S Z copy group.
