Forgive me, but I forgot to write down the last argument (0) to the command
to delete the device-entry.

The correct commands are:

#dsfngr -Z rm_cluster_hwid 48 0
#dsfmgr -Z rm_local_hwid 48 0

I've corrected these lines already in the attached procedure.
Regards,

Gotfried

============================
corrected command-lines:

> #dsfmgr -Z rm_cluster_hwid 48 0 < I forgot to write down the last 0
> #dsfmgr -Z rm_local_hwid 48 0 < " " " " "
> " 0
============================

> 10.)assign name dsk2 to dsk7:

> #dsfmgr -V -m dsk7 dsk2
>
> That's it.
