For those of you who have been following my recent work with Solaris platform integration, be sure to check out the work Cindi and the FMA team are doing as part of the Sensor Abstraction Layer project. Cindi recently posted an initial version of the Phase 1 design document. Take a look if you're interested in the details, and join the discussion if you're interested in defining the Solaris platform experience.
The implications of this project for unified platform integration are obvious. With respect to what I've been working on, you'll likely see the current disk monitoring infrastructure converted into generic sensors, as well as the sfx4500-disk LED support converted into indicators. I plan to leverage this work as well as the SCSI FMA work to enable correlated ZFS diagnosis across internal and external storage.
