If that's the problem I think it is, then changing /etc/hostconfig to
hardcode a hostname may provide a fix.  The hostname is used as part
of the encryption key.  If the hostname changes, TSM won't just fail
to decrypt the password but it will actually delete the TSM.PWD
file.  Very annoying.  This is IMHO a design flaw that needs to be
addressed.  In the meantime, I suspect that hardcoding the hostname
in /etc/hostconfig may provide a workaround.

We are having a problem where TSM scheduled backups fail when a Mac
is put to sleep and woken up again. The symptom looks to be the same
as in APAR IC48146, the TSM.PWD password file is deleted. However,
the fix for that APAR appears to work only if the Mac is shutdown or
restarted, not when it is slept. The Mac will start scheduled backups
again after you launch the TSM Backup for Administrators program and
enter the TSM password when prompted.

Has anyone else had this problem? It is driving our PowerBook users
nuts because backups won't work after they come back from taking the
computer on travel and the computer has been slept because of a
closed lid or aggressive Energy Saver settings when running on battery.
