Before issuing the paircreate command, verify that the secondary volume is
not mounted on any system. If the secondary volume is mounted after
paircreate, delete the pair (pairsplit –S), unmount the secondary volume,
and then reissue the paircreate command.
•
The operation of creating a pair is shown below.

Figure 1-2: Pair Creation Operation
•
NOTE: The paircreate command terminates before the initial copy
operation is complete (except when the nocopy option is specified). Use
the pair event waiting or pair display command to verify that the initial copy
operation completed successfully (status changes from COPY to PAIR, or
from COPY to PSUS if the –split option was specified). The execution log
file also shows completion of the initial copy operation.
