There would appear to be an i/o error reading information off one of the disks.

You should also make sure that there is adequate space in the /var filesystem, because that is where Ignite puts its temporary files. At least 30 MB must be free.

I hope alos, you are on the latest version of Ignite for 10.20. You can't get new versions for 10.20 any more, but you can from your old application cd's. The last set was cut in December of 2001.

I'm not sure whether make_recovery was replaced with make_tape_recovery on 10.20 but that is also worth looking into.

If your system can handle it, a 11.00 upgrade at the very least might be a really good idea.

Are you absolutely sure your tape drive is functioning normally? It appears to me that you have a problem with the tape drive.

Can you use tar to write and then read information from the tape? You might also want to clean the tape drive.

I do agree with Steven in that you really should be using make_tape_recovery rather than make_recovery. You can get the latest version of Ignite/UX for HP-UX 10.20 from here:
http://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=IGNITEUX

I am not 100% sure of the exact version number but I know for a fact that it does have the make_tape_recovery command. The version I have on my 10.20 machines is A.3.7.95.

The command I use on all my systems is:

# /opt/ignite/bin/make_tape_recovery -a /dev/rmt/?mn -I -v -m tar -x inc_entire=vg00

The above command will back up your entire VG00.

The first thing you need to do is get your tape drive fixed, though.

Hi,
Upgrade to the latest Ig-UX using swinstall. The link is below

http://www.software.hp.com/products/IUX/download.html

New command to take Ig-Ux backup.
#make_tape_recovery -x inc_entire=vg00 -Iv -a /dev/rmt/0mn

Note that the site that Tamil mentions only has the 'B' version of Ignite/UX which will only run on 11.0. For 10.20 you need the 'A' version from the site I mention.

Hi,

You check the your disk using the

dd if=/dev/dsk/(whatever ur disk) of=/dev/null bs=1024k

thanx

Have you tried a different tape? Have you tried a brand new tape? If you get the same result with those I would say that you probably have a bad tape drive since you can write to, but not read from the tape.

Please try on another tape ( preferably new ) I have seen, if Ignite backup fails on a tape for some reason, it may fail on the same tape even after fixing the original cause.
Try installing latest version of Ignite. It is available at
