Yes, this is on 3.1_STABLE with the FreeBSD emulation
package (thanks to
manu for getting tw_cli working and getting it pulled up to
3.1).
Here's an example:
backup 1# tw_cli info c0
Unit UnitType Status %Cmpl Stripe Size(GB)
Cache AVerify
IgnECC

u0 RAID-5 OK - 64K 1490.44 ON

You should as far as I know at least get a kernel message if
something
goes wrong with the RAID. My RAID controller reports the
status of
the RAID in the kernel messages:
ld0 at icp0 unit 0: <PD_A000>, type: RAID-1, status:
optimal <---
And if I remember correctly I got another kernel message
when something
went wrong with it (the original firmware apperently had
trouble with
disks >128GB).
Kind regards

Yes, something like that is exactly what I'd expect. But
there is
complete silence from the Adaptec adapter even when I pull
disks,
reinsert them and in general try to trigger some reaction.
No, sorry, "silence" is not true. There is an
acoustic alarm from the
RAID controller itself... but that really doesn't help me
much for a
remote system in a hosting facility
