In reading over the IBM procedure for upgrading atape
on AIX (article 1174910), it says to removed the tape and
lib devices from AIX (rmdev -dl fmtX). Is this really
necessary?  Can you just drop them to a defined state
(rmdev -l rmtX) for the upgrade so as to not mess up
the paths?  Also, is it really necessary to uninstall
the previous version, or can you just do a smitty upgrade.

Thanks

Rick
