Thank you all.
I got the problem more clearly now.
I would believe it's a hardware problem, i mean, cable , power supply but
not the hardisk itself. It's a external disk and it went down when SUN
engineer was here doing some hardware maintances. I was not there so I
didnt know how much he has done to rescue the hardisk. Anyway, I will take
the hardisk to computer store and find out what on the earth is the problem.
Belows are the original question and replies I've got, thank you all !!!
You guys are great !!
Regards,
Tony.

Original Question.
-----------------------
Hello,
I have a big problem here, one of our hardisks suddenly died.
The only message in the system log is: /dev/sd2 off line. Afterwards, the
sparc station is not able to detect that hardisk again. I am wondering
where the problem might be. THat hardisk is pretty new (2 years old
actually) and has no problem before. Can anyone point me a direction ?
Regards,
Tony.

Can you see the disk when you do a probe-scsi?
If you can't then maybe one scsi boards has gone bad.
Are all of the connections/cables seated properly?
Have any of the scsi cables been bumped or moved around.
Does anything different appear in /var/adm/messages?
Did any core files get generated?
How did you find the problem?

Sorry to say that disks just die for no good reason sometimes. Can you
see it when you do a probe-scsi-all at the prom level? I would suggest
calling in Sun and replacing it. I have seen disks less than a month old
die...
Good luck,
Brian

That means the system knew about the disk, but it didn't respond to
selection when it tried to address it. You might want to check to
see if a) it is spinning b) it has +5/+12 on the power connector.

check that the power supply to the disk is working properly. try to
see if the enclosure works with other devices, or put the disk in
another known good enclosure.
hope this helps, -john

have you tried doing a probe-scsi at the OK prompt, it
could be just a scsi cable problem. You should
get a report back of the scsi target id adn peripherl
type when you do: probe-scsi or probe-scsi all.
If it does not check the cable, if it does but system can
not detect, try booting with: boot -r option.
hope this helps.

Hi Tony,
Have you done a probe-scsi from the monitor. If you can't detect it from
there, it could be a scsi problem, also, I had an external harddisk that
ran continuously for 1.5 year in fairly harsh conditions (sometimes the
room temp would get up to 85F/30C) and when I shut it down for a few
hours, it wouldn't wind up again. Seems that the lubricant on the disk
spindle gelled.
If it's an external drive, I would take it off the computer and make sure
it winds up seperately, then try a probe-scsi on a couple of different
machines, change cables, terminators etc.
This is *highly* unlikely, but if all else fails, make sure your root
partition is not corrupt (was your machine reboot a few minutes prior
to the disk failure?)
Hope this helps,

Take the system down..
Power cycle all..
As the system comes up, go to Prom mode.. and do a
probe-scsi-all
If your system does not see the drive at this time, then it has truely joined
Elvis. If it does see it, then continue booting and let me know..

Dear Tony,
I first would replace the cable and boot again to single user mode and probe once again for devices. If you have other drives after this one that are working this may not be the problem.
Hope this helps,
James Scobee
