2 TB disks don't exists yet (at least on the servers). So even if RAID
controller dont allow logical volume (most do allow),
you always can have < 2 TB disk raids.
I agree that it is a problem, but it is not Novell problem - it is general
partitioning problem. Don't create LUN's more then 2 TB, and always select
RAID controllers with logical volume options on them (so that you can
allocate few LUN's smallert then 2 TB out of 10 TB raid-5).
You server is not useles.. Boot it in bios, open RAID configuration. Select
any 2 physical disks, configure RAID-1 on them, allocate them to LUN0.
Select other disks, allocate few RAID-1s or one RAID-5 on them, allocate
other LUN's. Install and use system. Where is the problem?
