Hi Paul,
 
A question about the medium attributes: ADC2r05a clause 5.3.1 states, 'Attributes established when no medium is present shall be applied to the next medium loaded.'  We're not sure how to interpret this sentence when a load operation fails.  What did you intend?  Should the device server apply the medium attributes to the next successful load or should it clear the attributes when a load operation fails?  Thanks.
