Staging Problems with NW 7.3.1 (7.3 too)

[a060463xyz]

Networker Server 7.3 or 7.3.1 is not staging.
using the management console Monitor->alerts shows the Message "waiting for one writable Tape or disk in Pool xyz"
xyz is the Pool defined as target in the staging policy.
Of course are one or more writable Tapes of this pool located in the library, sometimes a Tape of this pool is mounted in a tapedrive but nothing happens.
If you eject the tape manually and reinsert it manually the staging takes place.
I have placed a call to emc but sofar nothing usefull resulted.
To avaid a full diskdevice I schedule a script via cron or at (Windows) :

lib=mylib
dev=mydevice
P=mypool
targettape=$(mminfo -r "volume" -q "pool="$mypool",%used<full,location="$lib")
nsrjb -u -f "$dev"
nsrjb -l -f "$dev" "$targettape"

(with Windows iam using a gnu bash tool to run the script)

With this crude script running at times after backup ist completed ( 7 am) the staging takes place.

Now my questíons :
Has anyone experienced the same behaviour, opened a call with the same issue or has a solution to that problem ?
