If a TrueCopy for Mainframe M-VOL is in pending status and you execute an ICKDSF command for Version 2, the

ICKDSF job will end abnormally with CC=12 error. For information on how to avoid that abnormal ending, see

(page 148)

If you establish a Version 2 relationship with the FREEZE option when a Version 2 S-VOL and a TrueCopy Synchronous
for Mainframe R-VOL are shared, the results of Version 2 operations and TrueCopy Synchronous for Mainframe operations
will be as follows:

Results of Version 2 operations

When the status of a TrueCopy Synchronous for Mainframe pair is Suspend, the command will end normally, and
you can establish a Version 2 relationship. However, when the status of a TrueCopy Synchronous for Mainframe pair
is either Duplex of Pending duplex, the command will be rejected and you cannot establish a Version 2 relationship.

Results of TrueCopy Synchronous for Mainframe operations

If a Version 2 relationship is established with the FREEZE option and if a TrueCopy Synchronous for Mainframe R-VOL
is in the extended long busy (ELB) status, the command to create or resume a pair will be rejected. However, the
command to suspend or delete a pair will be executed normally.

When you use a Version 2 S-VOL as the TrueCopy for Mainframe R-VOL, configure the system as follows:

Connect the different hosts to the main storage system and remote storage system, or connect the host of the main
storage system to both the main and remote storage systems.

Use the Fibre Channel interface to connect the main storage system with the remote storage system.

3

You cannot establish the Version 2 relationship because the data consistency of the Version 2 T-VOL will not be insured.

However, this system configuration differs from the system configuration that is used when IBM
FlashCopy Version 2 and PPRC are used in conjunction with one another.

describes whether or not you can perform the Reverse Restore when you share the

Version 2 S-VOL and the volume of a TrueCopy for Mainframe pair.

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)

S-VOL and the volume of a TrueCopy for Mainframe pair.
