FMA

I was about to write a new blog on Solaris' Fault Management Architecture when I realized my friend Bob Netherton has beaten to it by almost 3 years.

We like to tout the benefits of FMA a lot, but it's often hard to demonstrate because you don't want to go around destroying CPUs and memory modules just to see FMA in action. However, by creating a ZFS pool with files as disks, it's quite easy to demonstrate and that's exactly what Bob does in his blog ZFS and FMA - Two great tastes ......

Note, there's also an FMA Demo Kit that you can use to simulate faults to other hardware components, but I haven't played with that myself yet. Other resources I found helpful:
