If TASK MANAGEMENT FUNCTION is set to ABORT TASK or QUERY TASK, the TAG OF TASK TO BE MANAGED field specifies the TAG value from the COMMAND frame that contained the task to be aborted or checked. For all other task management functions, the TAG OF TASK TO BE MANAGED field shall be ignored.

When a drive receives a TASK frame, the following fields are checked:

∙HASHED DESTINATION SAS ADDRESS field

When this field contains a value different from the hashed SAS address of the drive, the drive sends the ACK and CREDIT_BLOCKED primitives, and discards the TASK frame.

∙HASHED SOURCE SAS ADDRESS field

When this field contains a value different from that in the SOURCE SAS

ADDRESS field of the OPEN frame, the drive sends the

CREDIT_BLOCKED primitive, and discards the TASK frame.
