Hello everyone,

We have one tape with several backup blocks on it. The
first block is ufsdump, the second one is ufsdump and
the third one is vxdump.

Right now, I need to transfer the filesystem on the
third block to remote site. I am trying to use dd to
copy the third block to disk as following:

%mt -f /dev/rmt/0cn fsf 2
%dd if=/dev/rmt/0cn of=third.out bs=63k
read: Not enough space
0+0 records in
0+0 records out

May I just copy the third block on the tape rather
than the whole tape?

thanks & have a good weekend,

zhu
