Volumes that cannot be shared:
The Compatible FlashCopy and Cnt Ac-S Z shared configuration is different from the IBM FlashCopy
and PPRC shared configuration. For Compatible FlashCopy and Cnt Ac-S Z, you cannot create
the following pairs (see “Compatible FlashCopy and Cnt Ac-S Z: Non-Sharable Combination”
(page 23) ):
• A Cnt Ac-S Z pair that includes a volume functioning as both a Compatible FlashCopy T-VOL
and a Cnt Ac-S Z R-VOL.

When you share Compatible FlashCopy S-VOL and a volume of Cnt Ac-S Z pair:
You must do the following when you share Compatible FlashCopy S-VOL and a volume of Cnt
Ac-S Z pair, or when you use the Remote FlashCopy function.
• Specify only one Compatible FlashCopy-T-VOL if the Compatible FlashCopy S-VOL is shared
with Cnt Ac-S Z R-VOL.
• Specify the volume of the same emulation type and same capacity with Compatible FlashCopy
S-VOL to Cnt Ac-S Z S-VOL if the Compatible FlashCopy S-VOL is shared with Cnt Ac-S Z
R-VOL.
• Set the local mode (Mode 20 and Mode 190) to ON at RCU.
For details on how to set the local mode to ON, call the Support Center.
• Use the volume whose emulation type is shown in Table 17 (page 29).
When you share the Compatible FlashCopy S-VOL and the volume of a Cnt Ac-S Z pair, the status
of the Cnt Ac-S Z pair must be either duplex, pending duplex, or suspend. However, if the shared
Cnt Ac-S Z volume is a R-VOL, there may be cases when you cannot create the Compatible
FlashCopy relationship (see the following table for detailed information).
