Command Specifications

Note:

When “1” is specified in the “SelfTest (self test)” bit in this command, the command execution results are reported by the status byte and the sense data. Therefore, even if the RECEIVE DIAGNOSTIC RESULTS command is executed after this command, the self-diagnosis test execution results are not reported as response data.

Remark:

The error recovery control flag is valid only for PER. Therefore, the only error recovery flag combination that is actually executed in the above self-diagnosis tests is the (PER, DTE) = (1, 0) combination.

(2)Parameter specification

When “0” is specified in the “SelfTest (self test) bit in the CDB, the IDD executes the operations specified in the parameter list transferred from the INIT by this command. In this case, the IDD reports a GOOD status and terminates this command at the point when preparation of the “response data” is completed after completing the specified operations. The INIT can read the execution results (response data) by the RECEIVE DIAGNOSTIC RESULTS command.

When the “PF (page format)” bit in the CDB is “1,” the parameter list transferred from the INIT by this command shows the page format, explained later, but the IDD disregards the value specified in this bit and always handles the page format according to the specifications in the parameter list when the parameter list is transferred by this command. Also, when the “SelfTest (self test)” bit is “0,” the specifications in the “DefOfl (device off-line)” bit and the “UnitOfl (unit off-line)” bit have no meaning and their specified values are disregarded.

The “Parameter list length” field in the CDB shows the length (number of bytes) of the parameter list that is transferred from the INIT when the “SelfTest (self test)” bit’s specification is “0.” When zero is specified in the “Parameter list length” field, this command is terminated without anything being executed. Also, when the value specified in the “Parameter list length” field does not reach the specified length for the parameter list, explained later, and as a result, not all the bytes in the parameter list can be received, that command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST) [=5] / Invalid field in CDB [=24-00]).

Figure 3.18 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.
