Figure 3.29 Send Diagnostic Command: Parameter List Configuration - Fujitsu MAX3073NC - SCSI,80, Dell DC961,Hard Drive Scsi Logical Interface Specifications

Command Specifications
received, that command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST) [=5] /
Invalid field in CDB [=24-00]).
Figure 3.29 shows the format of the parameter list (called the parameter page) transferred from the INIT to the
IDD by this command. The parameter page is configured from the 4-byte "Page Header" and the "Page
Parameters" which follow it. Furthermore, the INIT can specify only a single parameter page by this
command. Even when multiple parameter pages have been specified by the INIT, the IDD executes only the
operation specified by the top parameter page.
Notes
1. When "0" is specified in the "SelfTest (self test)" bit in this command, the INIT can specify
only a single parameter page.
2. In order to avoid loss of security to the execution results (response data) of this command due to
another command issued by another INIT, when "0" is specified in the "SelfTest (self test)" bit,
the INIT should issue this command linked to the RECEIVE DIAGNOSTIC RESULTS
command or reserve the IDD before issuing this command, and should release the reserve status
after executing the RECEIVE DIAGNOSTIC RESULTS command.
3. When a command other than the RECEIVE DIAGNOSTIC RESULTS command is linked to this
command, the execution results (response data) may no longer be secure.
