Note – In this document, the phrase “DR detach operation” refers to the complete
detach or removal of a system board. This detach operation can be accomplished by
using the ADR command deleteboard(1M). For instructions on detaching boards
from Solaris 9 domains (which support only DR model 3.0), refer to the Sun
Enterprise 10000 Dynamic Reconfiguration User Guide (part number 816-3627-10).
