PAGE LENGTH field
The PAGE LENGTH field contains the length in bytes of the diagnostic parameters that follow this field. If the application client sends a SEND
DIAGNOSTIC command with a parameter list containing a PAGE LENGTH field that results in the truncation of any parameter, then the com-
mand shall be terminated with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to
INVALID FIELD IN PARAMETER LIST.
The diagnostic parameters are defined for each diagnostic page code. The diagnostic parameters within a diagnostic page may be defined dif-
ferently in a SEND DIAGNOSTIC command than in a RECEIVE DIAGNOSTIC RESULTS command.
