Sony DDS-4 Product Description Manual page 65

6. COMMAND SPECIFICATION
To achieve this, during the DATA OUT phase the initiator must send the log page header of the page to be cleared, with
the Page Length field set to 0. The following pages can be cleared in this manner.
Note: Due to the way in which logs are stored and updated, clearing log page 2 will
result in log page 3 also being cleared and vice versa.
Because of this method of clearing the log pages, the Parameter List Length field must be an integer multiple of the Log
Page Header length (i.e. 4). Otherwise the command will be terminated with a CHECK CONDITION status with the
sense key set to ILLEGAL REQUEST and an additional sense code of INVALID FIELD IN CDB.
If multiple pages are sent during this DATA OUT phase then they must be sent in ascending order according to page
code. Otherwise the command will terminate with a CHECK CONDITION status with the sense key set to ILLEGAL
REQUEST and an additional sense code of ILLEGAL FIELD IN PARAMETER LIST. The same status will be re-
turned if an unsupported Page Code appears in any header or if the specified page cannot cleared.
