Figure 88. Pre-Fetch (34)

The P R E - F E T C H command requests the file to transfer data to the cache. N o data is transferred to the
initiator.

Transfer length

The transfer length field specifies the number of contiguous blocks of data that are to be
transferred into the cache. A transfer length of zero indicates that blocks are to be trans-
ferred into the cache until the segment is filled or there are no more blocks on the media.

Immed

(Immediate) must be zero. An immediate bit of zero indicates that the status shall not be
returned until the operation has completed.

If the Immed bit is set to one, the drive returns a Check Condition status. The sense key

shall be set to Illegal Request and the additional sense code shall be set to Invalid Field in
CDB.

RelAdr

Relative Block Address is not supported. Must be set to zero.
