The first confusing part is that the 7899 does not do RAID-5 by itself, it is just a SCSI controller. I'll try to figure out what RAID you have.. umm... it is AACRAID/PERCRAID PERC3/Di ... um.... look at the web pages: http://domsch.com/linux/ http://domsch.com/linux/aacraid-old.html http://domsch.com/linux/aacraid/linux-2.2.20-aacraid-20020131-2.patch.gz This stuff is not included or supported in the tomsrtbt kernel and modules, you'll need to at minimum build your own driver, probably build your own kernel. Note, a simple google search for dell+linux+raid+2500 turned all of this up pretty quickly, you might want to check out the Google "help and how to search" page at: http://www.google.com/help/index.html
