Tsm 6.2.5 running on RHEL 6.1.

Install guide says you can upgrade straight to 7.1.1 from 6.2.x.

Extract the package downloaded from passport advantage, run install.sh.
Pick tsm server and tsm license to install.
Take default shared resource directory
Accept license agreement
Select install.

I get the following.

Looks like it isn't extracting the db2 upgrade utilities.
What have I missed?
