Re: [gentoo-server] SATA again...

[Nick Van Vlaenderen]

Hi Davin and all others,

Thanks. I booted into the gentoo livecd using the 2.4 kernel and I could
find the harddisks immediatly. The server is for production use, so I'm
going to use a 2.4 kernel combined with grsec. Anyway, I'm going to try the
2.6 series of the Linux kernel as well later on. Thanks everyone for all
information regarding SATA and RAID!

Nick,

You should be able to use SATA perfectly well, I am with a 2.6.4 kernel and
I've gotta say it ROCKS! Which SATA Chipset is it? If it's the Silicon Image
like my Shuttle here then you need to allow experimental drivers for doing
the build. But so far its sweet! Wouldn't give it up!

Hi Lima

Thanks for the info! I boot from the SMP kernel, 'cause I need it for my CPU
(it has Hyper-Threading...). But, you said the 2.6 series can't find any
SATA disks? Probably, that's the reason, since the SMP kernel is a 2.6.1
kernel...

Anyway, I am going to try the standard 2.4 Gentoo kernel.

I have several servers with a Intel 875PBZ motherboard, one SATA disk of
160GB, and a CD-ROM. In the bios there is a 'Drive Configuration'
section where you can choose your 'ATA/IDE Configuration' as 'Enhanced'
or 'Legacy'. The first one gives you the 2 PATA channels plus the 2 SATA
channel for a total of 6 devices (2 SATA and 4 PATA). Booting from
Gentoo-2004.0-universal CD with this configuration + RAID disabled, the
SATA disk is shown as /dev/hde (or /dev/hdf). If you want (for any
reason) to have your SATA disk as /dev/hda you should change to the
Legacy option selecting the configuration whith the 2 SATA channels +
the secondary PATA (where you put your CD). Booting in this
configuration (RAID disabled) shows the SATA disk as /dev/hda and the CD
Rom as /dev/hdc.
This is a copy&paste of the section in dmesg where the IDE drives are
detected whith a 2.4.24 kernel:

        Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
        ide: Assuming 33MHz system bus speed for PIO modes; override

        Partition check:

        ide: late registration of driver.

When I tried to boot from a 2.6 kernel, the SATA disk is not detected at
all in any BIOS configuration.

Hope this can help and not confuse...
