Get and install smartmontools. Period. I resisted it for a few weeks but it
has been an amazing tool. It will tell you more than you ever wanted to know
about any disk drive in the /dev/rdsk/ tree, down to the serial number.
I have seen zfs remember original names in a pool after they have been renamed by the OS
such that "zpool status" can list c22t4d0 as a drive in the pool when there
exists no such drive on the system.
Run smartmontools on a Linux LiveCD if necessary. For a while (at least
when OpenSolaris 2009.06 was released) smartmontools could not get drive
information on drives on certain controllers.
Why has it been reported as bad (for probably 2
months now, I haven't
got around to figuring out which disk in the case it
is etc.) but the
iostat isn't showing me any errors.
Start a scrub or do an obscure find, e.g. "find /tank_mointpoint -name core"
and watch the drive activity lights. The drive in the pool which isn't blinking like
crazy is a faulted/offlined drive.
Ugly and oh-so-hackerish, but it works.
You might also be able to figure it out from drive vibration or a lack
thereof. Many people rolling their own server hardware don't have
per-drive activity lights, hence the recommendation to figure out how to
identify drives in software via their serial numbers and then match up
with the labels.
