Vendor Unique
The SEND DIAGNOSTIC command requests the target to perform diagnostic
operations on itself, on the logical unit, or on both. The only mandatory implementation
of this command is the self-test feature with the parameter list length of zero.
If the specified test passes, a GOOD STATUS is returned. Otherwise, a CHECK
CONDITION is generated, and the sense data will contain information about the failure.
PF
The page format (PF) bit is not supported and must be set to zero.
SelfTest
The self-test (SelfTest) bit of one directs the target to perform its default self test. The
parameter list length must be set to zero if the SelfTest bit is set to one. A SelfTest bit of
zero is not supported.
DevOfl, UnitOfl
The device offline (DevOfl) and unit offline (UnitOfl) bits may be set in conjunction
with the SelfTest bit of one, if the parameter list length is zero. Any other combinations
with these bits are not supported.
Parameter List Length
The parameter list length must be set to zero.
