• Immed bit is to specify
0
Status is to be returned at the end of the operation.
1
Good status shall always be returned immediately after command has been received. The TEST UNIT
READY command may be used to determine when the drive becomes ready.
• AUSE bit can be set to 1 to allow EXIT FAILURE MODE service action on a subsequent SANITIZE. If AUSE is
set to 0, and the sanitize fails, a subsequent SANITIZE with EXIT FAILURE MODE will be rejected.
• Parameter List Length field specifies the length in bytes of the parameter data that is available to be transferred
from the application client’s Data-Out Buffer. When the Service Action is set to Overwrite (01) the Parameter List
Length specifies the length of the Overwrite service action parameter list. If the Service Action is any other value
than Overwrite (01), then the Parameter List Length must be 0. If not, the drive returns a Check Condition status.
The sense key is set to Illegal Request and the additional sense data is set to Invalid Field in CDB.
• VU stands for Vendor Unique.
• FLAG* If Link is zero, Flag must also be zero. If Link is one, Flag may also be one. Typically this bit is used to
cause an interrupt in the Initiator between linked commands.
• LINK* is set to one to indicate that the Initiator desires an automatic link to the next command upon successful
completion of the current command.
Note: * - The drive ignores the link bit and flag bit in the CDB.
