Oggetto: Disk error
  Hello,
  I get the following error when I execute the command
   #  dump -u0 -f /dev/ntape/tape0_d1 /
dump: Dumping from host pswxxx.psi.ch

     It seems that the disk is having HW problems. Can I save 
     the contents of the disk before it is completely dies?
     How can I save it to a tape or disk? Please specify the
     necessary commands. The machine is still in operation.
     Regards,
     Kumar
