I just purchased three IBM DNES-309170 drives and planned on using Vinum
to configure them in a RAID 0 and/or 5 setup. I have read a bit a vinum
and now I am trying to get the drives ready to be used in a few simple
vinum tests. however, i am running into some problems that i am hoping
you folks can help me with.
1. I can create FDISK partitions on the disk just fine. Once I get an
FDISK partition setup, I try to use disklabel to change the partition type
to vinum, but when i try to write the changes to the label, disklabel
tells me "operation not supported by device"
2. I have also tried to create slices in my FDISK partition just to test
the drive, but I am unable to create slices. I get the error
"Device rda0s1c: name slot allocation failed (Errno=17)"
Any ideas? Bellow I have included output from dmesg, fdisk, and disklabel
for reference. Thanks in advance for ANY help! :)
dmesg shows me this:

and fdisk /dev/da0 shows me this:

******* Working on device /dev/da0 *******
parameters extracted from in-core disklabel are:

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:

I am fairly new to this so hopefully I am just overlooking something
obvious that someone could point out to me. :)
ANY help would be appreciated.
