You don't have to make any changes to TSM to run the 3494 in manual mode. That 
is a 3494 library setting. I'm not sure that you can
define a drive in a 3494 as in a manual library (DEF LIBR LIBT=MANUAL).

I think there's a chapter in the 3494 operator guide that explains manual mode. 
No changes are required on any of the attached hosts
to the library when it's running in manual mode. Been a while since I've played 
with a 3494, but at another site we had
one...connected to TSM on AIX and a zServer mainframe. In the 4-years I was 
there, the robot only went offline twice. Just switched
to manual mode and got an aerobics workout!

We have a 3494. The last time we did a disaster recovery test our hotsite 
vendor gave use a group of 3590 tape drives without an
automated library. We got this to work by defining a new manual library and 
updating the relevant device class to associate it with
the new library. We did not make any changes in storage pool definitions.
