The RECEIVE DIAGNOSTIC RESULTS command requests that analysis data requested by a SEND
DIAGNOSTICS command be sent to the initiator.
!

shall define the data returned by this command. PCV bit of one indicates that the contents of the
Page Code field shall define the data returned by this command.
!
Parameter List Length
specifies the amount of data to be returned to the initiator. This value may
be zero and this is not considered an error. The drive terminates the DATA IN phase when all avail-
able data has been transferred or when the number of bytes transferred equals the Parameter List
Length.
