Table 129 Deadline handling Subcommand (1h)
Normal Outputs
If this Deadline Handling Subcommand command is supported, the device returns the command completed with no
error.
When a Deadline Handling Subcommand command completes successfully, a Set Device Bits FIS is sent to the
host to complete the Deadline Handling subcommand. This SDB FIS may also indicate other completed
commands.
Error Outputs
The device returns command aborted, if:
a) NCQ is disabled and a DEADLINE HANDLING command is issued to the device;
b) The value of the TTAG field equals the value of the TAG field;
c) The value of the TTAG field is an invalid TAG number; or
d) An unsupported Abort type parameter is specified.
