The RECEIVE DIAGNOSTIC RESULTS Command Descriptor Block is shown in

 

 

 

Table

-156; the data fields are described in Table 5-157.

 

 

 

 

 

 

To receive one or both of the two diagnostic pages that are available, the initiator first

 

 

 

sends the desired page code(s) to the drive using a SEND DIAGNOSTICS command.

 

 

 

The SEND DIAGNOSTICS command tells the drive which page it should return in

 

 

 

response to the next RECEIVE DIAGNOSTICS RESULTS command. The page

 

 

 

specified in the most recent SEND DIAGNOSTICS command is always the page

 

 

 

returned in response to the RECEIVE DIAGNOSTICS RESULTS command.
