I believe some more info is needed of my setup.
I'm running Sol9x86 on a Tyan Tiger 2721-ugn motherboard. This has builtin
Adaptec AIC-7902W Dual channel SCSI controller. On Channel A I have a 36GB
hard drive running as the system drive. On Channel B (my external channel) I
have an external Storcase DS560 RAID Array. This array uses an Accusys SCSI
to IDE Raid Controller. I have it loaded with 5 X 250GB drives in a RAID 5
configuration. The controller shows the Array to be 1TB. When I boot into
solaris and run SMC or format it shows up as 512GB.
Tim Chipman gave some insight with the following:

Does anyone know if this is true for Solaris 9 x86 before I break my array
and reinitialize it with 2 LUNs?
I also got some info about installing the SUNWqus and SUNWqusu drivers but
isn't that just the driver for the Sun dual channel ultra-3 SCSI card or
does it just add support for larger LUNs?
Thanks
