FlashCopy to Cnt Ac-J Z Primary Volume function
The FlashCopy to Cnt Ac-J Z Primary Volume function allows you to share Compatible FlashCopy
T-VOLs and Cnt Ac-J Z P-VOLs. When you share Compatible FlashCopy T-VOLs and Cnt Ac-J Z
P-VOLs, the status of the Cnt Ac-J Z pairs must be Duplex, Pending duplex, Suspend or Suspending.
Also, you can either create Cnt Ac-J Z pairs after creating Compatible FlashCopy pairs, or create
Compatible FlashCopy pairs after creating Cnt Ac-J Z pairs. However, Compatible FlashCopy
pairs can be created after creating Cnt Ac-J Z pairs only when the following options are used:
• DFSMSdss : FCTOPPRCPRIMARY
• TSO : TGTPPRIM(YES)
• ICKDSF : TGTOKASPPRCPRIM(YES)
• ANTRQST Macro : TGTPPRIM(YES)
For details about using Compatible FlashCopy with Cnt Ac-J Z, see “Using Compatible FlashCopy
with Continuous Access Journal Z” (page 26).
• The Cnt Ac-J Z program product is required for using the FlashCopy to Cnt Ac-J Z Primary
Volume function.
• The FlashCopy to Cnt Ac-J Z Primary Volume function can be used regardless of the status of
Cnt Ac-J Z.
• Data that Compatible FlashCopy copies to Cnt Ac-J Z P-VOLs are transferred to Cnt Ac-J Z
S-VOLs asynchronously. Cnt Ac-J Z displays the progress of this asynchronous data transfer.
Depending on the timing of the Compatible FlashCopy and Cnt Ac-J Z copy operations, a
time delay may occur between the Compatible FlashCopy copy operation and the Cnt Ac-J
Z copy operation, and the Cnt Ac-J Z asynchronous data transfer may progress slowly.
The copy process of Compatible FlashCopy pairs and Cnt Ac-J Z pairs by the FlashCopy to Cnt
Ac-J Z Primary Volume function is the same as that of the FlashCopy to PPRC Primary Volume
function.
Releasing Compatible FlashCopy relationships
Issue the TSO FCWITHDR command to release a Compatible FlashCopy relationship. There is no
DFSMSdss command for releasing Compatible FlashCopy relationship.
