John Worden asked that this item be deferred.

4.3    SAS COMMAND ID Removal (02-259) [Day]

affect item C. It was noted that the recently-added QUERY TASK task management
function enables this alternative to the COMMAND ID.

proposal (02-279) [Fairchild]

Steve Fairchild was unable to attend the call and, by email, asked that this
item be deferred.

In the absence of Mark Evans this item was deferred.

4.7    LED driver [Lohmeyer]

John Lohmeyer noted that the SAS Physical working group is now pursuing a
direction of just one LED driver strength of approximately 15 mA. So there is
no longer a need to find 2 bits to control the LED driver strength. This
