6. If the T-VOL is set to offline in step 4 , set this volume back to online. This step is not necessary if the
ONLINTGT parameter of the FCESTABL command is set to YES.
NOTE: FCESTABL command can only be executed once per FlashCopy Mirror Version 2 pair. In
other words, you cannot execute this command repeatedly for the same FlashCopy Mirror Version 2
pair.
Figure 59 shows an example of how FCESTABL command is used. In this example, the FCESTABL
command specifies that the data on the extent starting from CCHH '01000004' and ending at CCHH
'0357000A' in the source device numbered 4202 is to be copied to the extent starting from CCHH
'13000001' and ending at CCHH '15570007' in the target device numbered 4203, and the operation
mode for copying to the extent starting from CCHH '18A00000' and ending at CCHH '18F30006' is to
be set to NOCOPY mode.

Figure 60 shows another example of how FCESTABL command is used. In this example, the FCESTABL
command specifies that the data in the source device numbered 4202 is to be copied to target device
numbered 4203 by COPY mode while 4202 is online.
