no backup blues

[Daffner Marcus]

Dear colleagues,

the fbackup (via SAM) won??t work on companies 9000/J220 HPUX 11.00 machine.
Trying to interactivelely backup the whole system (w.o. NFS) I received the following error message:
fbackup(3205)WARNING: unable to read a volume header
fbackup(3024): writing volume 1 to /dev/rmt/0m
fbackup(9999): I/O error
fbackup(3120): write error on a record in the index
fbackup(3025):write error at the beginning of the volume

after that I can only more abort the operation.
Trying to forward the tape via mt -f /dev/rmt/0m fss 20 dumped: fss 20 failed: I/O error; the tape is brand-new, the backup device is an HP C1533A (referring to ioscan), clean led is not active;
do I need to mount the tape in advance or is it simply broken respectively dirty?

Thanks for any suggestion

Marcus

Marcus,

You are using a dds-2 tape, correct?

Here's the C1533A main link:

Have you tried with tar or cpio?
I had faced a similar problem where it was working with tar and failing with fbackup. Then we put a call to HP and they have replaced the DDS3 drive and now everything is working fine.

It is bettere to give a call to support.

Hi Daffner,

Looks like you need a replacement tape drive. You can try a sample tar / cpio backup just to make sure the fbackup binaries are not corrupted.

The first few messages are normal since you are using a new media, (it is unable to find a header)

fbackup(3205)WARNING: unable to read a volume header
fbackup(3024): writing volume 1 to /dev/rmt/0m

The problem is I/O error.

Try to take a sample tar / cpio backup and if even that fails, try to get a replacement drive.

hope this helps.

thanks to your hints I tried out tar (tar -cv -C /) which returned 0; strange is: the whole operation took less than 10 mins, but the systems size is about 2 G and after all I got positively no experience with backups it seems very short to me; so, as SAM doesn??t work, how can I check the content of my DDS2 tape?

thanks again

Hi Daffner,

Try this,

ioscan -fnkC tape

This will give you the device file associated with the backup device. say it is /dev/rmt/0m, now do a tar backup

tar cvf /dev/rmt/0m some_directory

Check the contents of the tape,

tar tvf /dev/rmt/0m

To try the same with cpio, try this,

find . -print |cpio -iCBvdul >/dev/rmt/0m

To check the contents of the tape,

cpio -itBvdul
If the backup performed using these is okay, you should look at the fbackup command you are trying. If both of these give you problem, replace the drive and try.

Hope this helps.
