Hi again,

and thanks to Graeme Elsworthy <> and Jeff Stewart 
<> for their replies.
Graeme suggested to re-initialize the devs and dids with scdidadm and 
devfsadm, and Jeff mentioned that scdidadm -u -i could help.
Hm, I did this, and after a reboot (this was scheduled for another 
maintenance work), magically the second quorum appeared, although still 
offline. But, after removing + re-adding it, it was online.

I really don't know if the DiD-cleanup , or the reboot solved the 
problem, but, it is solved...

Thanks to the list,

and have a nice hackin',
