Subject: raid 0 question
Date: Thu, 08 Mar 2001 00:55:11 -0500
I have a Promise ata100 controller that I am trying to do IDE Raid
with.
The system that preexists the RAID is a fic 503+ via mvp3 based ata33
motherboard. Other IDE devices include: western digital 5400
rpm drive on IDE0 (hda) and a ATAPI zip on ide0 as well. CDROM on
IDE1, (there used to be a second hard drive on ide1 but for now now cdrom
is alone).
There is a Mandrake7.2 installation on /dev/hda5 - hda9. I am using
Reiserfs on all partitions except swap. There is also an Advansys fast
SCSI card for my scanner - no drives are connected to it.
I can't get the new hardware completely installed and recognized by the
system.
So, I have read through some basic instructions on RAID device creation
and I have had the card in the PC and have trying to hook up the new IDE
drives. I have two virgin ata/100 Quantum fireball plus AS 30gig drives
for this purpose. But I can't seem to get more than one attached!
The BIOS initializes the Promise card no problem.
There is no problem attaching the first Quantum drive to the card on its
first channel (using Promise supplied cable). The Promise card detects
while the system is in BIOS booting. The Mandrake system on /dev/hda5
boots up with one drive attached as hde on the Promise card and the
drive is seen in dmesg and looks accessible to hdparm, fdisk, etc.
Then I attached a second cable to the second Quantum drive and hook it
up to the Promise ata100 on its second IDE channel. Everything seems
fine in the BIOS sequence the card detects the second drive on IDE3 -
but when Linux boots from hda5, the bootup halts.
it comes to a halt after reporting the c/h/s of hda - right where it
would report hde's cylinders heads and sectors.
I have copied what I see in the console at the point booting fails.
Hopefully this will mean something to someone.

and that's where the bootup halts everytime.
Is there an IRQ conflict going on with both IDE2 and IDE3 claiming IRQ11
? If so why did they bother selling people this crap? I have tried
swapping master/slave jumper settings starting with IDE2's quantum being
set for master and IDE3's quantum set for master also. I have tried
putting IDE3's drive in slave mode (without making it a second device on
IDE2) There is no change - the boot always fails at the same place even
though the Promise BIOS detects the drive however it is set. I have
verified both the cables i need to use to connect the ata100 drives.
They are both 3 plug 80 conductor IDE cables of the same length, and if
used alone, they both work. (I haven't tried connecting both drives to
one cable since that would defeat the purpose of IDE RAID)
Can anybody who knows how this is done and especially someone who's done
software RAID on IDE help me figure out what is wrong with what I'm
doing?

Hoo, boy! Lew, you bring a point home well. Thanks! You see: as I rummage
through all the tools provided freely by dedicated Linux software
programmers, I've noticed a distinct lack of familiar MS-DOS/Windows-style
tools (like Norton's Utilities...after all, what's Windows without Norton?).
So I figured I'd ask.
I thank you for your well-thought-out answer. I'm very much at home on the
PC in MS products. But I got there (as did many others) with a little help
from my friends. Thanks for not throwing RTMs at me. Much of my manual
reading time has been spent with MS products.
Now it's off to new challenges and new discoveries: Linux!

Subject: Re: PCI IRQ Steering under Linux?
Date: Wed, 07 Mar 2001 22:45:42 -0800
It depends on the kernel version, the devices in conflict and the kernel
configuration.
I had a problem with a USR hardware modem sharing an IRQ with my HPT366
controller. After a lot of work and research (and help from Usenet
contributors), I corrected the problem without changing the hardware
configuration and both share an IRQ successfully. Unless you hear
information from someone who has been through it, you may get conflicting
information and misdirection based on assumptions and theories.
My configuration was:
ABIT BE6-II, HPT366 Controller, USR 56k 2977 hardware modem, kernel
2.2.10, Caldera 2.3
All worked fine except that the modem was reported as "busy" and could
not get dialtone. I had to manually pass ide parameters (e.g.,
ide0=0xb400,0xb802) to boot the kernel.
Then, I updated the kernel so that it could support the HPT366 and
upgraded my serial device driver to support IRQ sharing.
My configuration now:
Same as OLD but kernel 2.2.16 + hpt366 patch
(http://linux.nf/ultra66.htm) + serial 5.05
(http://serial.sourceforge.net). I boot the kernel without passing ide
parameters.
Newer kernels such as 2,4.x may already include support for your devices.
Let me know if I can provide anymore info.

Hello.
I have Fasttrack 100 working on a Redhat7. I need to kompile 2.4.2 kernel. I
have not the source code for the Fasttrack100 and Promise is not willing to
send it. So I have only the compiled drivers that are available from promise
home page. How can I compile the new kernel? I have tried it. It started to
boot, but it has ended with Kernel panic
Last free rows are:
request_module[block-major-8]: Root fs not mounted
VFS: Cannot open root device "801" or 08: 01
Please append a correct "root=" boot option
I am sure that I have correct boot option in Lilo.
How can I compile the kernel with the Fasttrack enabled?
Thanks

See "man lspci" and "man setpci" for these tasks.

Basically, PCI devices _can_ share interrupts, assuming that both
the hardware and the drivers for the various devices support it.
However, with the ATA100 controllers (Promise etc.), this does not
work - at all. The Promise controller as built into most of today's ATA-
100 compatible motherboards, does not like IRQ sharing, and you'll
have to make sure that the controller receives an IRQ of its own.

See relevant comments on the doubtable quality of the Netgear FA310
controller. A PCI NIC can and will share IRQs, even with devices
that issue or receivce lots of IRQ requests on the same line.
My USD $ 20.-- RTL8029 card does happily coexist with my Dawi
SCSI controller. Try a different slot, or use a different NIC.

It's amazing the difference a non-proportional font makes in such diagrams.
The diagram says,

There is a real simple way, to do this. Just install arpwatch. It scans
your network permanently for IP- and MAC-adresses and sents you a meil, if
changes are detected. In var/lib/arpwatch you will find a file with all
your current ip/mac-adresses.
