3. Set the TCzA R-VOL to online.
The host will be able to recognize the dataset on the TCzA R-VOL and figure out the extent for creating
a FlashCopy® Mirror Version 2 pair.
NOTE: If the same host is connected to both TCzA M-VOL and R-VOL, the R-VOL label must be
rewritten.
4. Use DFSMS to create a FlashCopy® Mirror Version 2 pair. See the following example:
COPY FULL INDYNAM(xxxxxx) OUTDYNAM(yyyyyy) FASTREP(REQ) FCCOPY
For details about the DFSMS to create a FlashCopy® Mirror Version 2 pair, see ”DFSM Command
Supported by Compatible Mirroring for IBM FlashCopy Version 2”.
5. If step 4 completes successfully, set the TCz Synchronous R-VOL to offline.
6. Resynchronize the TCz Synchronous pair.
Using a TSO command
Follow the procedures below if you use a TSO command when FlashCopy® Mirror Version 2 S-VOL
and TCz Synchronous R-VOL are shared
. For details about the TSO command for creating a
FlashCopy® Mirror Version 2 pair, see ”Creating FlashCopy Mirror Version 2 Pairs: FCESTABL”.
Using a TSO command when FlashCopy® Mirror Version 2 S-VOL and TCz Synchronous R-VOL are shared
1. If you need to terminate the I/O operation to the volumes of TCz Synchronous pairs in order to
maintain the consistency of data, terminate the I/O operation.
2. Use the TSO command to create a FlashCopy® Mirror Version 2 pair. See the following example:
FCESTABL SDEVN(X'xxxx') TDEVN(X'yyyy') MODE(COPY) ONLINTGT(YES)
Using a TSO command when FlashCopy® Mirror Version 2 S-VOL and TCzA R-VOL are shared
1. If you need to terminate the I/O operation to the volumes of TCzA pairs in order to maintain the
consistency of data, terminate the I/O operation.
2. Suspend the TCzA 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 create a FlashCopy® Mirror Version 2 pair. See the following example:
FCESTABL SDEVN(X'xxxx') TDEVN(X'yyyy') MODE(COPY) ONLINTGT(YES)
4. Resynchronize the TCzA pair.
Combining Compatible Mirroring for IBM® FlashCopy® Version 2 With XRC Replication
Table Figure 54 shows combination of the volumes when you use FlashCopy® Mirror Version 2 with XRC
Replication.
Table 54 Compatibility of Volumes Shared by FlashCopy Mirror Version 2 and Security Solutions
FlashCopy
Mirror Version 2
XRC Replication
P-VOL S-VOL
S-VOL OK NO*
T-VOL NO NO
*Do not share FlashCopy® Mirror Version 2 T-VOL with XRC Replication S-VOL. If
a T-VOL (S-VOL) is shared by both FlashCopy® Mirror Version 2 and XRC
Replication, the data in the T-VOL (S-VOL) will be overwritten by the two programs
and will be destroyed.
