Comparison of Results of TrueCopy for Mainframe Pair Operations
TrueCopy for Mainframe pair operations sometimes produce different results depending on whether
differential data of the TrueCopy for Mainframe pair is stored in units of tracks or cylinders. See
(page 45) .

No Yes Is it possible to use TrueCopy for
Mainframe pair volumes that are not
suspended to create Version 2
relationships?
Yes. However, you cannot
resynchronize a TrueCopy for Yes Is it possible to use suspended
TrueCopy for Mainframe pair volumes
to create Version 2 relationships?
Mainframe pair when a volume in the
TrueCopy for Mainframe pair is also
used as a Version 2 volume.
No Yes Is it possible to use Version 2
relationship to create TrueCopy for
Mainframe pairs?
No Yes Will background copy be performed
if a Version 2 relationship has been
created in NOCOPY mode?
When the Version 2 relationship is
copied in units of tracks. When the Version 2 relationship is
created. When will differential data of the
TrueCopy for Mainframe pair be
updated?
Transition of Pair Synchronized is
different depending on whether the
data was stored in units of tracks or
cylinders.
