Format Unit Command (04 H ) - Seagate MEDALIST 1080SL Product Manual

32 Medalist 1080sl SCSI Product Manual, August 1995
3.4.4 Format Unit command (04
The Format Unit command assures that the medium is formatted so that
all of the addressable data blocks can be accessed. In addition, the
medium can be certified and control structures may be created for the
management of the medium and defects.
If the specified logical unit is reserved, the Format Unit command is
rejected with a reservation conflict status. Extent reservations are not
supported. See Section 3.4.11 for more information about reservations.
The initiator can specify (or not specify) sectors to be reallocated during
the formatting process.
