That can't be good. That's just screaming "dead, uncabled, or removed".

Useful hint where to start if all else fails (see below)

So you know where it was previously, and you can't find it now because
it's either dead, missing, or there's no fiberchannel path to it.

Exactly as it says: Check the cabling, check the enclosure for a failed disk,
and check if there's now an empty spot where a co-worker "helpfully" removed a
bad disk.
