• The case the T-VOL of the FlashCopy Mirror Version 2 pair and the T-VOL of the Siz pair is shared.
Figure 53 Cases When FlashCopy Mirror Version 2 and SIz Cannot be Used in Conjunction
When you use FlashCopy Mirror Version 2, you cannot create pairs sharing the volumes shown in
Figure 53 . However, if you use ShadowImage for z/OS, you can create the pair which shares FlashCopy
Mirror Version 2 S-VOL and SIz T-VOL, or the pair which shares FlashCopy Mirror Version 2 T-VOL and SIz
S-VOL.
The following table shows the combination of volumes when you use FlashCopy Mirror Version 2 with TCz,
URz, or XRC.
The FlashCopy Mirror Version 2 and TCz, URz, or XRC and TCz, URz, or XRC shared configuration is
different from the IBM FlashCopy and PPRC shared configuration. For FlashCopy Mirror Version 2 and
TCz, URz, or XRC, you cannot create the following pairs:
• A TCz pair that includes a volume functioning as both a FlashCopy Mirror Version 2 S-VOL and a TCz
R-VOL, URz S-VOL, or XRC SVOL
• A TCz or URz pair that includes a volume functioning as both a FlashCopy Mirror Version 2 T -VOL and
a TCz M-VOL, URZ P-VOL, or XRC P-VOL
• A TCz or URz pair that includes a volume functioning as both a FlashCopy Mirror Version 2 T-VOL and a
TCz R-VOL, URz S-VOL, or V=XRC S-VOL.
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.
