Hi Tom

I haven't used 4.2.1.7, but did it install a new TSM devices component as
part of the upgrade.

Normally when the TSM devices are installed or upgraded on AIX they do a
bosboot that requires a reboot of the machine to take fully effect.  I've
had similar device problems after install that were cleared by a reboot.

It's just a thought, but have you rebooted Aix since applying 4.2.1.7 ?
