Hum... the server is a bit less than 2 years old, and all disks are
plugged on the same back-plane, so I would be surprised if it was a
cabling issue.  And, since I have spares, I prefer to replace the
suspect disk to be safe and test it later...  If it is indeed a
cabling issue, the new disk will also look failed I guess.

If it helps, cfgadm -alv says:
sata0/2  disconnected unconfigured failed

I did not yet go onsite to witness if there is any red led.

Thx,
