1 You can perform Reverse Restore when you specify the following options:
• DFSMSdss : FCTOPPRCPRIMARY (You cannot perform Fast Reverse Restore when you specify DFSMSdss.)
• TSO : TGTPPRIM(YES)
• ICKDSF : TGTOKASPPRCPRIM(YES)
• ANTRQST MacroTGTPPRIM(YES)
“Whether Fast Reverse Restore Can be Performed When a Version 2 S-VOL is Used as a TrueCopy
for Mainframe Volume” (page 58) shows whether Fast Reverse Restore can be performed when
you share the Version 2 S-VOL and the volume of a TrueCopy for Mainframe pair.

• 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 “Emulation Types Supported by Version 2”
(page 64). 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 “Whether Version 2 T-VOL
Can be Used as TrueCopy for Mainframe” (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.
