• 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.
