In case you missed it amid the Yuletide holiday festivies, today's light reading assignment is NetApp's latest United States Patent # 7,310,747 B2:
SYSTEM AND METHOD FOR DIAGNOSTICS EXECUTION AND DATA CAPTURE IN A STORAGE SYSTEM USING NONVOLATILE MEMORY
In other words, running boot_diags off of CompactFlash.
As a former IT guy running NetApp arrays, I've seen some pretty interesting environmental diag codes over the years. Of course, a 100,000,000 volt lightening bolt does funny things to your power sensors.
