NAME
gdt
—
ICP-Vortex and Intel GDT SATA/SCSI RAID
controller
SYNOPSIS
gdt* at pci?
DESCRIPTION
The gdt
driver provides support for
ICP-Vortex adapters such as:
GDT4x13RZ, GDT4x23RZ, GDT6000/6020/6050, GDT6000B/6010, GDT6110/6510, GDT6120/6520, GDT6513RS, GDT6518RS, GDT6523RS, GDT6530, GDT6535, GDT6537, GDT6537RP, GDT6537RP1, GDT6537RP2, GDT6550, GDT6555, GDT6557, GDT6557RP, GDT6557RP1, GDT6557RP2, GDT6x11RP, GDT6x11RP1, GDT6x11RP2, GDT6x15, GDT6x17, GDT6x17RP, GDT6x17RP1, GDT6x17RP2, GDT6x18RD, GDT6x19RD, GDT6x21RP, GDT6x21RP1, GDT6x21RP2, GDT6x25, GDT6x27, GDT6x27RP, GDT6x27RP1, GDT6x27RP2, GDT6x28RD, GDT6x28RS, GDT6x29RD, GDT6x33RS, GDT6x38RD, GDT6x38RS, GDT6x43RS, GDT6x53RS, GDT6x58RD, GDT6x58RS, GDT6x63RS, GDT7x13RN, GDT7x18RN, GDT7x19RN, GDT7x23RN, GDT7x28RN, GDT7x29RN, GDT7x38RN, GDT7x43RN, GDT7x53RN, GDT7x58RN, GDT7x63RN, GDT8x00RZ, GDT8x13RZ, GDT8x14RZ, GDT8x22RZ, GDT8x23RZ, GDT8x23RZ, GDT8x24RZ, GDT8x33RZ, GDT8x43RZ, GDT8x46RZ, GDT8x53RZ, GDT8x63RZ, and GDT8x86RZ.
As well as Intel adapters such as:
SRCU42L, SRCU32, SRCZCR, and SRCS14L.
Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done through the controllers' BIOSes.
DIAGNOSTICS
- pci_mem_find: expected mem type 00000000, found 00000002
- This message occurs during autoconfiguration if jumper J4 is set to map the controller memory below 1MB in physical memory. The driver primarily wants this jumper to be set the other way round, but it will work with it in any setting. If the diagnostic is considered a nuisance, alter jumper J4's setting.

OpenBSD 2.7.

The gdt
driver was written by

inspired by the Linux driver by Achim Luebner

BUGS
An ISA & EISA front-end is needed.
The driver does not support transparent raw SCSI mode.
It would be nice to configure the RAID units after boot but the information on how to do that is not public.
