The RECEIVE DIAGNOSTIC RESULTS Command Descriptor Block is shown in
Figure 5-75; the data fields are described in Table 5-75.
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.
