Notes:

  1. The volume performs differently according to the type of difference management.
  2. For more information, contact customer support.
  3. If you use TCz with Compatible FlashCopy® V2, the TCz pairs must be created without using the consistency groups.
  4. See the section about compatible software in the Compatible FlashCopy® User Guide for VSP One Block 85.
  5. When you create Compatible FlashCopy® V2 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 TCz pair is in Duplex status. To release this status, delete the TCz pair.
  6. In a 3DC multi-target or 3DC cascade configuration with three URz sites, the volume shared with two URz pairs cannot be used with TCz. Likewise, a volume used with TCz cannot be used as a volume shared with two URz pairs.
  7. The pair creation or the pair resync operation is available.
