Software Reset SAS Controller 
If the disk configuration is not displaying properly, users can issue a software-reset 
signal to the embedded SAS controller using the button located on the Maintenance 
menu page.  If users have hot-swapped many disks, this ensures the SAS controller 
has completely purged internal tables, and is properly presenting the new or 
remaining disks to the operating system.
