Figure 64 FlashCopy® Mirror Version 2 and TCz: Non-sharable combination
NOTE: For IBM FlashCopy and PPRC, you can create a PPRC pair that includes a volume that functions as
both a FlashCopy T-VOL and a PPRC primary volume, and a PPRC pair that includes a volume that
functions as both a FlashCopy T-VOL and a PPRC T-VOL.
When you share FlashCopy® Mirror Version 2 S-VOL and the volume of TCzA pair, you need to:
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.
Create only one FlashCopy® Mirror Version 2 pair for one TCzA pair. You can specify one
FlashCopy® Mirror Version 2 T-VOL for one TCzA M-VOL (FlashCopy® Mirror Version 2 S-VOL).
Use the volume whose emulation type is 3380-3, 3390-1, 3390-2, 3390-3, 3390-3R, 3390-9, 3390-L
or 3390-M
When you share the FlashCopy® Mirror Version 2 S-VOL and the volume of a TCz pair, the status of the
TCzA pair must be duplex, pending duplex, or suspend. However, if the shared TCz volume is a R-VOL,
there may be the cases that you cannot create the FlashCopy® Mirror Version 2 pair. Detailed information
about this is in Table 53.
