- We need access to an array that supports the PERSISTENT RESERVATION cdb's
- before we can proceed
-*/
-/* scsi bugs:
- INQUIRY takes a 2 byte allocation_length parameter but it appears that
- it only looks at the low byte. If you specify 0x00ff all is well
- but if you specify 0x0100 it gets confused and returns garbage data
- for (e.g) SupportedVPDPages. Same goes for UnitSerialNumber and probably all
- other inq pages as well.
