Below is the working group proposed text:
When compressed data is encountered on the medium that the device server is
unable to decompress, the device server shall return CHECK CONDITION status.
The sense key shall be set to MEDIUM ERROR, and the additional sense code
shall be set to CANNOT DECOMPRESS USING DECLARED ALGORITHM. Undecompressed
data may be returned to the application client as a single variable length
logical block with the ILI bit and INFORMATION fields set accordingly. The
logical position is vendor specific following this condition.
Note XX: the undecompressed data may contain more than one logical block,
filemark, or setmark. As such, the application client should issue a READ
POSITION command following this condition to re-establish positioning.
Let me know if there are any issues.
