I am currently working on upgrading a system that is running 3.2v4.2
with the Y2K patch installed. The system is used for a monster
database and we want to increase the speed of disk accessibility.
Towards these ends we installed a DPT Century V (PM2654U2)controller
with 32 Mb of cache for one drive. The cache has helped significantly
with the new drive, however we want to take this further and actually
get an array running. I installed 2 Seagate 18.2 Gb ultra 2 lvd drives
and set them up as a RAID 0 stack after disconnecting the existing
drive. The problem is that 3.2v4.2 doesn't see the RAID stack after
this at all. The Controller reports it as a 36.4 Gb DPT drive, 4444
cylinders, 255 heads an 63 sectors. I have tried the emergency boot
disks and the install disks. Nothing is recognizing it. I have not
found anything on the net about the limitations of 3.2v4.2 on drives.
Is it just the size, the fact that it has 255 heads or what? Any
suggestions would be greatly appreciated.
