Thx for quick reply.But i tried to take tar backup of two large files & without any error successfully tarbackup completed on tapes...then how can you say that problem is with tape or tape drive.

[user001]

does it always use pax?

pax has a 2GB file size limitation. Just a thought. I don't remember seeing it use pax with ours, maybe you can specify a different archiver. I might be way off here though.

Any ignite patches available?

As it is an I/O error, either you have a problem reading the source (file system , disk) or writing to tape (drive,tape).

Note: Your ignite version is quite old and it is out of support.

[Bill Hassell]

Since your Ignite software is badly out of date, your pax program is probably out of date too. I would NOT use the -A option and instead add the -I (capital I). And to change backup method, add the option -m tar to the command line as well as -v to see more details:

#make_tape_recovery -a /dev/rmt/0mn -I -v -m tar -x inc_entire=vg00 -x exclude=/var/adm/crash -x exclude=/var/opt/backup

Don't run old Ignite software. Computers get new hardware (I/O cards, disks, tape drives) and you'll eventually run into problems. This also includes the latest patches for pax as well as tar. Since your Ignite software is so old, you will have to swremove the old copy and install the latest (C.7.12.519).

>Is it require reboot if I install the s/w again?

You shouldn't need to reboot to install ignite software.

These errors still indicate an I/O problem. And since a tar from an single lvol works OK, I am guessing that this tape drive is on the same bus as your disks. Please supply an ioscan -kf. As a note, LTO (Ultrium) drives are far too fast to be used on internal SCSI cards or shared with any other disks. LTO drives should be on a dedicated Ultra320 SCSI interface. Otherwise, they should be on a fibre connection (2Gbit or faster).
