See anything about the disk in /var/adm/messages?
ditto for dmsg output?
What's the OS, revision level, and hardware this is running on?

Part of me wants to say "Call a sysadmin over to the computer to take a 
look", but I'm giving you the benefit of the doubt here (along with your 
use of english grammar--but I'd mess up french just as badly).

Yes, your disk died.  Hope you had a backup...

You could try power cycling it, and/or re-seating it, but at the end of
the day the most likely answer is that your drive has gone to the big
datacenter in the sky.

What hardware? What disk? old one? What O/S version? Which mount point(S)?

Likely your disk died. The other posters suggest logs to check.

However, if this is funky old gear (like the kind I've liked to tinker
with) it just might be that the disk is not spinning up. Did this happen
during normal operation? or after poweroff/up again? Some of the bigger,
old drives would sometimes have the heads "stick" to the surface, harder
than the motor's starting torque. Wouldn't budge. I don't know if this is
some deterioration of the interior surface (landing zone?) or what. If
this is the case (and if you have backups, etc.) you might try lightly
tapping on the side of the drive as it is trying to spin up.
Alternatively, stand the disk on its side, instead of flat. The intention
is to try to jiggle the heads sideways (NOT up/down) to break free of the
surface contact, so they can start sliding. Once the disk comes up to
speed, the heads are flying on a cushion of air. Note that any kind of
mechanical shock to the disks could just as likely cause a head crash!
OTOH, if you're already sure your disk is "toast", then you've got nothing
to lose. If, by some miracle, you do get the disk spinning, then get all
your latest stuff off it, NOW! This kind of jiggery/pokery will only work
once or twice. If not already totally dead, your disk soon will be.

BTW, shouldn't this really be in comp.sys.sun.hardware?

Sometimes you can stick them in a freezer or oven for a couple of hours 
to cool or heat them up [under 130F please, your not baking a cake or 
making icecubes] to normal operating range to break the bearings and 
spindle free, quantums were famous for this, one of the fastest ways to 
find the root drive in an older sun was to look for the seagate or 
western digital drive among the 10 or so quantums, a sure giveaway :-)
