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 .
