ufsdump question

I've got a Seagate Ultrium Viper 200 on a E3500.
When I do a ufsdump of file systemsystems that are
"small," a few hundred meg, I'm fine but when I
get to my 7 - 22 gig file systems, I get write
errors.  I know I can backup these because the
tapes hold 100gigs uncompressed (plus someone
backed up the files yesterday but closed out the
command tool before I could write down the options).

The script I've been using is
#!/sbin/sh

ufsdump 0ubf 128 /dev/rmt/0cbn /;
ufsdump 0ubf 128 /dev/rmt/0cbn /usr;
ufsdump 0ubf 128 /dev/rmt/0cbn /var;
ufsdump 0ubf 128 /dev/rmt/0cbn /u03;
ufsdump 0ubf 128 /dev/rmt/0cbn /u04;
ufsdump 0ubf 128 /dev/rmt/0cbn /u02;
ufsdump 0ubf 128 /dev/rmt/0cbn /u01;
ufsdump 0ubf 128 /dev/rmt/0cbn /home;

mt offline;


And the log file looks like this (Note it doesn't
backup /u04, /u02, /u01, but does backup /home
which is the last file system in the script and
the last from df -k):

Have you tried a ufsdump without the "b 128" option? I've seen some cases where a large record size causes a problem. Another thing that could be a problem is if the system's idea of the device characteristics is different from the real device. What happens if you try backing up the failing file systems first? Does the fault follow the file system or occur towards the end of the process like above?

I have this problem.
The tapes is wrong !!
Replace the tapes with news
and try again.

Thanks for the help so far.

Otetelisanu: I've got a box of brand new tapes, I've gone
through 5 so far and gotten the same problem.

jlevie : Yep, tried without the b and have tried to backup
just one failed system at a time.  Same results.

I did find a diag tool for solaris viper 200 (Which tech
support said did not exist.  They told me I'd have to test
 my tapedrive from a NT box).  Anyway, it came back with
 errors.  A much more helpful tech support suggested checking the terminator and to slow the scsci bus down to
 40 bps.  

Anyone know how to do that?  I'm told the terniator light
being on isn't good enough.  Also, can this been done with
the machine live or do I have to rearrange my weekend?

Hi
ufsdump defaults to 4mm dat tapes
you have to give it some paramaters to make it lnow the tape size .
use this command instead
ufsdump 0dsbf 54000 13000 128 /dev/rmt/X filesystemname
d =density
s=size of tape in meters
this will wrok on aexabyte 7/15 tape
for larger ones just change the density and size to whatevr you want

I believe barazani may be correct, which is how I'll recommend if nobody speaks up.
