The domain contains 3 disks , other 2 disks are fine.
I checked the disk using , varify and fixdmn commands. It is saying Media nonrecoverable.
Is it possible to copy using DD command on that disk to some new disk and swap this corrupted disk with new disk?? Will it work??
I am planning to do salvage on that disk at the end .
I dont have proper backup.
Thansk in advance..

Re: One Disk in Domain is corrupt.
Is there a red or amber colored light on on the disk? If so, the disk is gone.
You say the disk is one of three. Is it a RAID-5 set or did you add volumes to the domain with the addvol command? A RAID-5 will reconstruct the data when you replace the bad disk.

Re: One Disk in Domain is corrupt.
Thanks for ur reply...
Disks are not in RAID :(.
Now I am running Salvage command on that domain.This is generation lots of files like below.
tag_197102, tag_311810, tag_tag_27072 .
Are these files useful to restore?? Only I recovered some 20% of data.
Thansk & Regards,
Shashi

Re: One Disk in Domain is corrupt.
Sorry but I've never used the salvage utility before so I can't help you there.

Re: One Disk in Domain is corrupt.
I think salvage will not recover complete data,have you tried mounting the disk somewhere else.

Re: One Disk in Domain is corrupt.
Having a proper backup is always essential when you are dealing with important data.
'Tag' is the internal name assigned to the user files. So, tagXXX refers to a particular user file in the file system.
You could see the manpage of 'salvage' or google to learn more about the file names generated by it.
(I don't have a 4.0 machine here to confirm it)
