You didn't tell us the important thing - your ADSM/TSM client level.
You may be running an old client, which in the past has run afoul
of automount file systems, where stopping the automounter may be
a circumvention.

By reason, the "system error (nnn)" should reflect the Unix errno value
returned by a system subroutine.  But the AIX 4.3.3 errno does not go as
high as 157 (see /usr/include/sys/errno.h), which indicates that there
was some garbage in the errno global variable - possibly there when the
client module invoked whatever subroutine it invoked, and which it assumes
is meaningful when the subroutine returns control.
