I do not believe this is a case where failmode is used -- the pool state is 
not FAULTED.

In my experience, this is a case where the disk is there, accepting commands,
but not actually responding. Eventually, (by default for most Solaris-derivative)
after 60seconds * 3 retries, something else is attempted, that also fails. Also in
my experience, I see this on consumer-grade drives (qv TLER discussions). 
However, we can't know more until we see the "fmdump -eV" error log descriptive
output.
