tru64 goes down to halt

I have a server alpha es40. its os is tru64.
the server has gone down to p00>>> everyday for last 3 days.
the server has been working without any problem for 4 years. We didn't install any addition software recently.
when it becomes crash, I boot it . it works for a while. after that it goes down.
I investigated the messages on it.

An AdvFS domain panic has occured due to either a metadata write error or an internal inconsistency. This domain is being rendered in accessible

sizer -v

Hmmm. Do you think it may be a bad disk?

> [...] Volume: /dev/rz8g

Possibly that one?

Re: tru64 goes down to halt

Hi,

It sounds very much like you have a failed or failing disk.

Repair/replace the disk.
Restore from your backups as appropriate.

Cheers,

Re: tru64 goes down to halt

You could try reassigning bad blocks.

Check out the man page and the help for scu.

How old is this disk drive? What would a
replacement cost? How much time would you
like to spend playing with a cheap piece of
obsolete (and failing) hardware? What is
your time worth?

Re: tru64 goes down to halt

I have 3 advfs partitions

disklabel -r rz8

rrz8a
rrz8g
rrz8h
I booted the server on single mode.
when I run "/sbin/scu -f /dev/rrz8a"
I doesn't get any error. scu prompted
scu>
when I run "/sbin/scu -f /dev/rrz8g"
scu>
when I run "/sbin/scu -f /dev/rrz8h"
scu>
is it normal ?
I see /var/adm/messages
Vmunix: syncing disks AdvFS I/O error
Vmunix: Volume: /dev/rz8g

Why didn't the utility able to find any bad blocks?

Thanks
