I hope that you can help me. I have done several backups with make_tape_recovery, in differents tape's and with different's content (last of them, was a full backup, entire backup of all my vg), but all fails when I try restore it.
This is the log:
---------------------------------------------
(...)
x ./monitor_bpr, 20480 bytes, 40 tape blocks
* Download_mini-system: Complete
* Loading_software: Begin
WARNING: Positioning tape failed: I/O error (errno = 5).
ERROR: directory checksum error
* Installing boot area on disk.
* Enabling swap areas.
* Backing up LVM configuration for "vg00".
* Backing up LVM configuration for "vg01".
* Processing the archive source (Recovery Archive).
* Fri Aug 13 07:48:01 EDT 2010: Starting archive load of the source
(Recovery Archive).
* Positioning the tape (/dev/rmt/0mn).
fsf 1 failed: I/O error
ERROR: run_cmd(/usr/bin/mt -t /dev/rmt/0mn fsf 1)
ERROR: Cannot move the tape forward. Cannot extract the OS archive.
The configuration process has incurred an error, would you like
to push a shell for debugging purposes? (y/[n]):
---------------------------------------------
As you can see, the problem have relationship with the tape positioning.
I always have had problems with commands as mt when I use rew or fsf options in my daily HP-UX use, receiving I/O errors.
I think that Ignite backup need use this functions and this is the cause of my problem.
Anybody can help me?
Thank you very much,
regards

Solution1) try using a cleaning tape to clean the tapedevice. That might help
2) use a new tape.
3) rewind the tape before starting ignite.
Also: what kind of tapedrive are you using? Ignite is not supported on all kinds...

Re: Problem for restore an Ignite backup
"3) rewind the tape before starting ignite."
Do you refer before made a backup or before restore it?

Re: Problem for restore an Ignite backup
Finally, the problem was the Tape Array unit.
The sequence that I done:
1.- Try two clean tape
2.- Try new tapes
3.- Change the tape unit for a new tape unit
4.- Change the tape array chasis (keeping the old SCSI cabel, SCSI terminator and power supply).
This last step, fixed the problem.
