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

(page 63)

. 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

(page 58)

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.

describes the TrueCopy for Mainframe pair status that is required when performing a

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