PREFERRED
The COPY utility directs DSS COPY to use fast replication if possible. If FlashCopy® cannot be used, then DSS uses traditional data movement methods.
REQUIRED
The COPY utility directs DSS COPY to only use fast replication, ensuring that object copies occur as quickly as possible. This option causes the COPY utility to fail if FlashCopy cannot be used. This option might reduce the opportunity for resource contention and unavailability for SHRLEVEL REFERENCE copies.
NONE
The COPY utility directs DSS COPY not to use fast replication. Traditional data movement methods are be used.
