ShadowImage for the XP128/XP1024/XP10000/XP12000
shows the emulation types supported by FlashCopy Mirror Version 2, and the condition for
combination of S-VOL and T-VOL.
If the emulation type begins with 3390, you can specify the volumes of different emulation types for S-VOL
and T-VOL. However, you cannot create a pair using a 3380-3 volume and a volume with an emulation
type that begins with 3390. In the case of a 3380-3 volume, you must specify 3380-3 volumes for both
S-VOL and T-VOL.
NOTE:
Whether or not you can perform the copy via host depends on the status of the URz pair. For more
information, see the Universal Replicator for z/OS® User’s Guide.
