Yes.  (I only recently rebooted to check.)

The system seems to be working fine; those log messages are the only
indication of any problem.  If we did not monitor our syslogs closely,
we probably would not even have noticed.

Wouldn't this appear in the logs too?

Ah, this is exactly what I was looking for.  Thank you!

Again, thank you.

I was starting to bring it up as a secondary DNS server, secondary NTP
server, and so on, with the idea of making it a primary for various
services which are currently running on even older hardware.  It is
still early enough that I can blow it away without too much pain.

I will double-check these.

Do these systems have an internal temperature monitor which I can
check from Linux?

It is under warranty, and I am running the 32-bit diagnostics now.
With any luck that will turn up something.

The yellow blinking "X" light on drive 3 turned off when I rebooted,
but the PERC BIOS still says that drive 3 is "returning errors" during
POST.  That might just be a stale message, though.

I suppose I can just pull the drives one at a time.  1) Pull drive, 2)
wait for RAID to rebuild, 3) replace pulled drive, 4) mark it as hot
spare, 5) return to step (1).  The trouble is that this looks like an
intermittent problem; it took several days to show up the first time.

Thank you again for the quick and useful reply.
