1. The volume performs differently according to the type of difference management.
2. For more information, contact the HP Technical Support.
3. If you use Cnt Ac-S Z with Compatible FlashCopy, the Cnt Ac-S Z pairs must be created without using the consistency
groups.
4. See the section on compatible software in the HP P9000 for Compatible FlashCopy Mirroring User Guide.
5. When you create Compatible FlashCopy Preserve Mirror relationships in COPY mode, both copies are not
synchronized. If you issue Withdraw during the copy operation, both copies of the relationship are suspended.
Therefore, the consistency of the data between P-VOL and S-VOL is not ensured even though the Cnt Ac-S Z pair is
in Duplex status. To release this status, delete the Cnt Ac-S Z pair.
