How to use 200 GB Disk on Ultra10?

["Roland Rick" <rri@gmx.net>]

Hi everybody

I have an old Ultra10 and want to use it as RAID1 mirror. Unfortunately I
may not correctly see my 200 GB disks...

Open Boot PROM: 3.11

Disk parameters, Maxtor modell 6Y200P0:
HDS:SECT    = 16:63
Max Cyls    = 16'383
MaxLba      = 398'297'088
Act Cyl     = 395'136
GB Capacity = 200

If I try to partition with "s" an Sun device, and entering with "0"
- 16 heads (default)
- 63 sectors (default)
- 16'381 cylinders (default: about 4567, cannot remember exactly)
- 2 spare cylinders (= 16'383 physical cyl.)
- interleave factor 1 (default)
- 0 extra sectors per cyl (defaut),
I get only a disk size of about 8 GB.

What make I wrong?
Is the disk size 200 GB not available for OBP 3.11?

=> Who knows a workaround?

I would really appreciate any help!

Cheers, Roland

PS: Happy new year!
