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.

Unlike using IBM FlashCopy Version 2 and PPRC together, you need a DFSMS command, a TSO
command, or an ICKDSF command when you use a DFSMS command, a TSO command, or an
ICKDSF
command are as follows. The procedures differ depending on whether Version 2 is used
in conjunction with TrueCopy Synchronous for Mainframe or with TrueCopy Asynchronous for
Mainframe. You cannot perform Fast Reverse Restore when you specify DFSMSdss.
•
Procedure when you use a DFSMS command
Follow this procedure if you use a DFSMS command. However, if the status of the TrueCopy
Synchronous for Mainframe pair is duplex, you need to use a TSO command.
If the Version 2 S-VOL and TrueCopy Synchronous for Mainframe R-VOL are shared:
1.
If you need to terminate the I/O operation to the volumes of the TrueCopy Synchronous
for Mainframe pairs to maintain the consistency of data, terminate the I/O operation.
2.
Suspend the TrueCopy Synchronous for Mainframe pair. See the following example:
CSUSPEND DEVN(X dev#') PRIM(X ssid' cmd_param X cca X lss)
SEC(X ssid' serial# X cca X lss)
3.
Set the TrueCopy Synchronous for Mainframe R-VOL to online.
The host will be able to recognize the dataset on the TrueCopy Synchronous for Mainframe
R-VOL and determine the extent for establishing a Version 2 relationship.
If the same host is connected to both TrueCopy Synchronous for Mainframe M-VOL and
R-VOL, the R-VOL label must be rewritten.
4.
Use DFSMS to establish a Version 2 relationship. See the following example:
COPY FULL INDYNAM(xxxxxx) OUTDYNAM(yyyyyy) FASTREP(REQ) FCCOPY
5.
If step 4 completes successfully, set the TrueCopy Synchronous for Mainframe R-VOL to
offline.
6.
Resynchronize the TrueCopy Synchronous for Mainframe pair.
If the Version 2 S-VOL and TrueCopy Asynchronous for Mainframe R-VOL are shared:
1.
If you need to terminate the I/O operation to the volumes of the TrueCopy Asynchronous
for Mainframe pairs to maintain the consistency of data, terminate the I/O operation.
2.
Suspend the TrueCopy Asynchronous for Mainframe pair. See the following example:
