￿￿￿￿￿￿￿￿(14/#6The Initialization￿70+6￿+PKVKCNK\CVKQPPattern ￿option2CVVGTPspecifies￿&GUETKRVQTthat the logical blocks on the drive medium will contain a specified initialization pattern. The Initialization Pattern descriptor is sent to the drive as part of the FORMAT UNIT parameter list. Table 5-19describes the Initialization Pattern descriptors. The contents of the descriptor fields are described in Table 5-20and the types in Table 5-21.

The Initialization Pattern Type field (Table 5-21) indicates the type of pattern

 

IP Type

 

 

the drive uses to initialize each logical sector within the initiator-accessible

 

 

 

 

 

 

 

portion of the medium. All bytes within a logical sector are written with the

 

 

 

 

 

 

 

initialization pattern.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Initialization Pattern Length field indicates the number of bytes contained

in the Initialization Pattern. The valid lengths (when IP Type = 1) are two or

 

 

 

 

 

 

 

four bytes.
