If I do a tape dump, but instead write it to disk, e.g.

dump 0auf - / >mydump.dmp

(Which dumps the root file system to a file called 'mydump.dmp') - and then
later either cp, dd or cat this to tape - why does a:

restore t /dev/rst0

Give:

tape read error: Invalid argument

And:

 /kernel: st0(ncr0:6:0): ILLEGAL REQUEST asc:20,0 Invalid command operation
code sks:c0,0

In the syslog? 

Normal dumps to tapes work fine... The exact error reported by the drive is
'block too big'.

I've tried reblocking the dump with something like:

dd if=mydump.dmp of=/dev/rst0 bs=512

But all to no avail...

Anyone got any suggestions?



Regards,

Karl
