DPO:
Disable Page Out.
If DPO = 1, the cache replacement algorithm should not replace existing cache data with the current data
(if possible). If a cache segment must be overwritten, it should be made the LRU.
FUA: Force Unit Access.
Read: If FUA = 1, the requested data must be read from the media. If cache data which overlaps
the request has not yet been written to the media, it should be written before the read is allowed to
occur.
Write: If FUA = 1, all data must be written to the media before the SCSI operation returns the
status and completion message bytes.
