Backup problem

so_2 — Mon, 18 Sep 2006 07:07:14 GMT

Hi all
I am getting the foloowing error while taking backup
fbackup -f /dev/rmt/1m -i /home
fbackup(1004): session begins on Mon Sep 18 12:24:35 2006
fbackup(3205): WARNING: unable to read a volume header
fbackup(3024): writing volume 1 to the output file /dev/rmt/1m

We checked by chnaging tapes either. I feel this as a drive problem. Any suggestion from you gurus? Any option that make no involvement of tape replacement will be highly apreciated.

Thanks in advance.
S.O

I would try cleaning the device before placing the Hardware Call to HP.

Following msg mean you are using a new tape for the first time.
fbackup(3205): WARNING: unable to read a volume header

Nothing is wrong. Unlike classic Unix tools, fbackup checks to see if the tape is an fbackup tape and whether it should be written. Because fbackup can handle multiple tapes, it always checks to make sure an operator error did not leave an earlier volume in the drive. If fbackup overwrote an earlier volume, that would be a very bad thing.

So, when you put a new tape, or a tape that was written with anything other than fbackup, you will get this "warning". Unfortunately, the message should be "informational". You can ignore the 3205 message.
