You can perform Fast Reverse Restore when you specify the following options:
•
TSO : TGTPPRIM(YES)
•
ICKDSF : TGTOKASPPRCPRIM(YES)
•
ANTRQST Macro: TGTPPRIM(YES)

Using a volume both as a Version 2 T-VOL and as a TrueCopy for Mainframe M-VOL
Volumes may be used as both a Version 2 T-VOL and a TrueCopy for Mainframe M-VOL as
long as they are any combination shown in
. In TrueCopy Asynchronous for
Mainframe, perform the following steps to create a volume that is both a Version 2 T-VOL and
a TrueCopy for Mainframe M-VOL.
1.
Create a TrueCopy Asynchronous for Mainframe pair.
2.
Set the status for this pair to Suspend.
3.
Create a Version 2 pair. The Version 2 T-VOL will become the TrueCopy for Mainframe
M-VOL.
Whether you can share the Version 2 T-VOL and the TrueCopy for Mainframe M-VOL depends
on the status of the TrueCopy for Mainframe pair as described in
.

An M-VOL cannot be specified as a Version 2 T-VOL (to create a Version 2 pair) unless a
TrueCopy Asynchronous for Mainframe pair is in the Suspend status.
•
Similarly, a Version 2 pair, whose T-VOL is also a TrueCopy Asynchronous for Mainframe,
cannot be deleted unless the TrueCopy Asynchronous for Mainframe pair is in the Suspend
status.
•
In addition, the TrueCopy Asynchronous for Mainframe pair cannot be resynchronized during
the time a volume is used both as a Version 2 T-VOL and as a TrueCopy Asynchronous for
Mainframe M-VOL.

Reverse Restore and Fast Reverse Restore if a Version 2 T-VOL and the volume of a TrueCopy for
Mainframe pair is shared.
