Darren Dunham and Rossman both hit the nail on the
head. They pointed out the bs,which I set according to
the backup command, is too small to hold the data from
tape. After I changed it to 256k, file is cloned from
tape successfully.:-)



---original question-------

: We have one tape with several backup blocks on it.
:> first block is ufsdump, the second one is ufsdump
:> 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
