fbackup/frecove and LTO

[Etienne Holm]

I have a problem with a LTO and fbackup.
We use fbackup to do system backup but never used it on an LTO device before. The scrip that I use checks the volume header but if the tape is an unused tape it will fail. If I use the same tape running the same script the backup will work with no problem.


If I take the new tape and tar a file to it before I start the backup the backup will also succeed with no errors.
I do not want to tar a file to the tape at the start of the backup as I will loose the header information and I cannot read the tape if it was not used before.

Have you checked your SCSi/fbackup patching levels?
These may have something to do with it.
Particularly the stape driver patch

[Frank Slootweg]

An unused tape should give only a *warning*, not a *failure*. Please post your script and the output/log from the 'failing' fbackup session.

[Etienne Holm]

This system is a new system installed in January so it was installed with HP_UX 11.11
December 2002 release (as far as I can see it has all the patches that was recommended for fbackup and LTO tape devices.)

Here is the backup script and a part of the log file. The backup_control script only check for the day and if it should do a backup or not.

[Frank Slootweg]

As I suspected, the unused tape gives only a warning for the missing volume header, but the real problem is that after that warning it gives write errors.

I can only suggest to check that you are fully up to date on patches, both for fbackup and frecover and for the SCSI and tape drivers. Also search the ITRC Forums on 'recent' threads for fbackup and Ultrium c.q. LTO.

Please realize that the combination of fbackup/frecover and a Ultrium/LTO drive is not supported (by HP). For a supported combination you have to use HP's OmniBack/DataProtector or a similar supported backup product.

I have these patches on the system or Ultrium drves.
PHCO_23914 1.0 Enhancement support to Ultrium tape

Is there other patches that is required for UX 11.11 and Ultrium?

As far as I know is that this system have the latest released patch bundel installed.

[melvyn burnard]

You may want to look at PHKL_28217 for htis one.
Just out of interest, what HP Product number does this device have

[Etienne Holm]

The product number is C7470A

I did a search for the patch but could not find it Can someone give me a url for it?

[Etienne Holm]

I found the patch but....
The patch PHKL_28217 is for Ultrium 2 and OmnibackI.
I do see how this will help in the problem I have currently.
