WRITE ERROR while writing checkpoint record, at media record 406272

fbackup(3012): WRITE ERROR while writing checkpoint record, at media record 406272
fbackup(3102): attempting to make this volume salvagable
fbackup(3105): writing 2 EOFs and rewinding the tape
fbackup(3106): please mount a good tape
fbackup(3310): enter 'yes' when volume 1 is ready on /dev/rmt/c0t5d0BEST,
or 'no' to discontinue:

This is the error we get when we try to take backup of file system in Tape.We use DLT tape that stores 40 - 80 GB.

Can somebody help me out of this!!!!!!!

Does the problem happen on multiple tapes, or just one?

it happens in all tapes, even new tape, i have even cleaned the tape drive many time.
The backup goes for 2-3 hrs and then this error comes.

I assume you are on HP-UX.

Can you install the HP-UX version of HP Library & Tape Tools (www.hp.com/support/tapetools), and then select the drive from the device list, select the support tool, and then save the support ticket to a file?

You can then post the .ltt file and I can review the drive error logs to see what the root cause is.

We would need to look at the drive error logs to see what is causing the failure, before knowing if a workaround is possible.

Here is the location of the HP-UX LTT install:

ftp://ftp.hp.com/pub/softlib/software3/COL1977/co-18247-1/hp_ltt34sr1a_hpux.tar

When you generate a support ticket using LTT, it will save it in a .ltt file (whatever name you give it). This is the support ticket file which you can then post, or email to ltt_team@hp.com, and I can review the drive logs.
