AIX - Installp command failing

I'm trying to install service pack from a directory where I staged all the .bff files. I get the following error below. Please help.

Here is what I did.

root@server:/> inutoc /staging/AIX_6.1

root@server:/> ls -l /staging/AIX_6.1/.toc
-rw-r--r--    1 root     system            0 Mar 09 15:55 /staging/AIX_6.1/.toc
