Hi sumit,

Are you using HP-UX 11.11? If yes then check that this patch is installed?

#swlist -l product|grep -i PHKL_34552

if not then install this patch. It requires reboot.

hi;
here is the solution; http://www.webservertalk.com/message392429.html
baseline, as the following;

The problem is that fbackup/frecover tries to read first only a few bytes (1
-10)
depending on the OS and fbackup/frecover version but the DLT's won't allow
this. With the 'remote device' fbackup/frecover doesn't try this directly.

In short, this doesn't work:

fbackup -f /dev/rmt/0m ...
frecover -x -f /dev/rmt/0m ...

but this works:

fbackup -f `hostname`:/dev/rmt/0m ...
frecover -x -f `hostname`:/dev/rmt/0m ...

-To use this trick you must be allowed to run a 'remsh' on your own host
