Default: REQUIRED

PREFERRED
The CHECK utilities direct DSS COPY to use fast replication only if FlashCopy® support is available.
REQUIRED
The CHECK utilities force DSS COPY to use fast replication, ensuring that object copies occur as quickly as possible. This reduces the opportunity for resource contention and unavailability. This option causes CHECK utilities to fail if FlashCopy cannot be used.
