Thank you for the suggestion, but it does not help.  There is some 
traffic on the list about the 3112, but I have a 3512, which does not 
have any list traffic about bugs.

The major thing that needs doing is a detailed explanation of how to 
take two brand new disk drives and mirror them.  Nothing in the 
documentation discusses this.  Do you have to create file systems on the 
drives first?  Do you have to use fdisk to slice them up?  Is there a 
size limit on drives?  I am trying to mirror two 400G drives, is this 
supported?  There is no information anywhere that I can find about these 
topics.
