- We have had (are having?) similar problems. We occationally get an error:
-
- DUMP: Tape write error 753 feet into tape 1
- DUMP: fopen on /dev/tty fails
- DUMP: The ENTIRE dump is aborted.
-
- At first, we suspected the tape but the same tape often worked fine for the
- next dump. More recently, we've been getting SCSI timeout errors during
- backup. I am now in the process of switching cables etc. I first changed
- servers but that didn't help. Now, I've changed the cable and am using the
- other SCSI port on the drive. I'm waiting for more problems to crop up.
- If anybody knows, definately, that there is a problem with dump, please post
- it. Thanks.
