5.27 RECEIVE DIAGNOSTIC RESULTS Command (1Ch)
The RECEIVE DIAGNOSTIC RESULTS command fetches the results of the last
SEND DIAGNOSTIC command sent to the drive. The drives support the diagnostic
pages listed in Table 5-149.
Table 5-149 Diagnostic Pages Supported by The Drives
The RECEIVE DIAGNOSTIC RESULTS Command Descriptor Block is shown in
Table 5-150; the data fields are described in Table 5-151.
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.
