sdsk: Unrecoverable Error (SCO Open Server rel5)
Can anyone please advise in relation to the error message:

Notice
sdsk: unrecoverable error reading SCSI disk 0 dev 1/43 (ha=0 id=0 lun=0) block=427254

It's most apparent while processing a large amount of data from a tape that is then run through an EDIfact translator.

I'm kind of assuming its a problem with blocks on the hard disk as the system tries to reference them.
I have run an fsck in single user mode but so far this has produced no fix.

Any help or advice gratefully received.

One thing that could cause this is a hard drive failure, but I don't think so in this case.

I have also seen this error caused by copying a large file that is also being written to by another process during the copy (i.e. backing up a database while in use). In this particular instance the way to eliminate the error is to delete the file in error. I am guessing your problem is somehow similar.

Are you getting any core dumps or system halts when the error occurs?

Is it possible the translator is erroring because its processing is faster than the tape restore and it is overrunning the end of the data?

Is it possible to restore all of the data before you pipe it through your translator?

Is it possible to lock down the system while you are restoring so that there aren't any data changes during the process?

hi,

you can try to run scsibadblk , and scan the block or range of blocks or whole disk to determine if there are any bad blocks on your hard disk , and if so mark them as bad so the bad block cannot be used anymore and then monitor the disk. If you get a lot of these then you have a problem with your hard disk and should get it replaced.
