17.3.11 Read Link Error Status Block (RLS)
RLS requests the recipient to return the Link Error Status Block associated with the Port Identifier specified in the payload.
The drive implements a Link Error Status Block for each port. When a counter overflows, it wraps back to zero. The only way
to reset the Link Error Status Block is to power off the drive.
Bytes 1, 2, and 3 of the payload must be set to zero. Otherwise, the drive will respond with an LS_RJT with a reason code of
“Command not supported” and a reason code explanation of “No additional explanation”.
Valid Port Identifiers are:
0Return the Link Error Status Block for the same port on which the request was received.
1Return the Link Error Status Block for Port A.
2Return the Link Error Status Block for Port B.
