Just cant change node attribute.
though no session with node  ( q sess)

Why TSM server respond:
The object you are attempting to access is currently in use by another
session or process. Retry the action at a later time.

all tsm client process on node are stopped (dsmsta, dsmc sched)
no hangin process on ports tsm used
TSM serv W2K3 and client AIX. All v.5.5
How can i cancel session in other ways? (canc sess dont work in this case
because we dont have any number of sess for node)

If restart tsm server this trouble is gone but maybe somebody knows
alternative?
