I received some reports about similar problems - some of them still unresolved 
and some hints where to take care for  (termination, firmware version, ....
  
Fortunately, I can get rid of the problem for the next few days.  The vendor 
who sold us the drives and Storage Works will take the entire disk tower in 
its  test/support  and check it  -- they are also  manufacturers of Sparc 
Clones  have equipment, test tools an qualified people.   Thus I can wait what 
they will find.  Now I hope they are successful analysts and that I get back 
a working disk tower - plug-in and use it  ----    
They asked to give them all the information about the problem. This way I will 
forward your hints to them. 
Thank You,
Werner Frank
