3. Set the TrueCopy Asynchronous for Mainframe R-VOL to online.
The host will be able to recognize the dataset on the TrueCopy Asynchronous for
Mainframe R-VOL and determine the extent for establishing a Version 2 relationship.
If the same host is connected to both TrueCopy Asynchronous 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 Asynchronous for Mainframe R-VOL to
offline.
6. Resynchronize the TrueCopy Asynchronous for Mainframe pair.
If the Version 2 T-VOL and TrueCopy Synchronous for Mainframe M-VOL are shared:
1. To maintain the consistency of data, terminate the I/O operation to the volumes of
TrueCopy Synchronous for Mainframe pairs. The TrueCopy for Mainframe pair status is
Duplex.
2. Use DFSMS to establish a Version 2 relationship. See the following example:
COPY FULL INDYNAM(xxxxxx) OUTDYNAM(yyyyyy) FASTREP(REQ) FCCOPY FCTOPPRCPRIMARY
• Procedure when you use a TSO command
Follow this procedure if you 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. Use the TSO command to create a Version 2 relationship. See the following example:
FCESTABL SDEVN(X'xxxx') TDEVN(X'yyyy') MODE(COPY) ONLINTGT(YES)
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:
CSUSPEND DEVN(X dev#') PRIM(X ssid' cmd_param X cca X lss)
SEC(X ssid' serial# X cca X lss)
3. Use the TSO command to establish a Version 2 relationship. See the following example:
FCESTABL SDEVN(X'xxxx') TDEVN(X'yyyy') MODE(COPY) ONLINTGT(YES)
4. Resynchronize the TrueCopy Asynchronous for Mainframe pair.
If the Version 2 T-VOL and TrueCopy Synchronous for Mainframe M-VOL are shared:
1. To maintain the consistency of data, terminate the I/O operation to the volumes of
TrueCopy Synchronous for Mainframe pairs. The TrueCopy for Mainframe pair status is
Duplex.
2. Use the TSO command to establish a Version 2 relationship. See the following example:
COPY FULL INDYNAM(xxxxxx) OUTDYNAM(yyyyyy) FASTREP(REQ) FCCOPY TCTOPPRCPRIMARY
• Procedure when you use an ICKDSF command
Follow this procedure if you use an ICKDSF command. For details about the ICKDSF command
for creating a Version 2 pair, see “Establishing Version 2 Relationships by Volumes Using the
ICKDSF Command” (page 91).
If the Version 2 S-VOL and TrueCopy Synchronous for Mainframe R-VOL are shared:
