first, what is the tray how could i start it,because after the command rcnovfsd start and restart the computer, i have the same error!!!
that command will not persist a reboot - that's a one-shot start of the daemon. The tray application is an end-user part, that part of the question was already answered by Malcolm.

Try (as root) additionally to run "insserv novfsd", which will tell the init subsystem to start novfsd on reboot.

I have no SLED system to test this, so YMMV.
