After digging through this kernel docs, the web, and this forum, and about three days worth of work, I finally managed to install Gentoo on a Proliant DL380. Let me tell you, while installing Linux on complicated hardware like this can be a real pain, once it is up and running, the pain all goes away as you bask in the glory of a superior operating system screaming away.

My installation fiasco involved having to install Gentoo twice. The first time, I hacked away trying to get it to work and rendered my system unusable. The second time, using what I learned from the first attempt, went pretty well.

Anyway, the point of this post is to share my trials and errors with my fellow Gentoo fanatics. So lets begin...

Pre Installation Step
You will have to use Compaq's Smart Start software to setup the array to your liking. Since I already had my array the way that I wanted it, I skipped this step.

Installation Steps
1) Pop in the Gentoo install CD and boot away. Run through the login, probe your PCI bus, install your NIC module and any other modules you need (cciss - see next step). I was booting off the array so I only needed the array module and no other SCSI modules.

2) Because the SmartArray is a hardware based controller, the array(s) will be recognized as a physical hard drive(s) and therefore you will not have to mess with any software RAID settings at all. You will, however, need to load the correct drive module to gain access to the array. For a Compaq SmartArray 5300, this module is cciss. So you will need to load this module: modprobe cciss.

3) Right here is where I started having problems. All documentation on the SA 5300 mentions the /dev tree entries as /dev/cciss/cXdXpX, where the X's stand for controller number, logical disk number, and partition number in that order. The problem is, when I loaded the cciss module, this structure was a bit different. I found the following:
/dev/cciss/disc0/ with sub directories listed below:
disc - Entire disc

This doesn't cause any major problems yet. So run fdisk to create your partitions, keeping in mind that you must reference the above disk: fdisk /dev/cciss/disc0/disc.

4) After you create your partitions, your /dev/cciss/ should look something like this:
/dev/cciss/disc0/ with sub directories listed below:
disc - Entire disc
part1 - My boot partition
part2 - My swap
part3 - My root partition

During the first installation attempt, the /dev/cciss tree actually did not update after I wrote changes and exited fdisk. I couldn't figure out why so I just rebooted. Everything was fine after that.

5) Once your partitions are created, make your folders and mount your volumes just like the Gentoo Install Doc says with one important addition: You MUST make the /dev tree available to your chrooted Gentoo environment otherwise Grub will not recognize any drives on the system (unless of course you have other IDE or SCSI drives). There seems to be more than one way to do this. The way I found to be the easiest was to bind the /dev tree using mount:
mount -o bind /dev /mnt/gentoo/dev

Before I did this, I was pulling my hair out trying to get Grub to find my drive. I was editing my grub.conf, sifting through Grub docs, and trying Grub commands. After all that, I then discovered that I couldn't access /dev/cciss/ because it just wasn't there.

6) After chrooting and modifying any make files, install Gentoo just like normal. When compiling the kernel don't forget to add in support for the array (Block Devices, Compaq 5xxx Array Support) and any file systems you are using.

7) The next trouble point, as I mentioned in step 5 was Grub. But, if you bound /dev to /mnt/gentoo/dev, half of the problems go away. Grub actually recognizes a drive installed on the system. So I ran:
grub> root (hd0,0) - Worked like a champ.
grub> setup (hd0) - Crapped out on me

Grub told me that it was able to find stage1, stage1_5, and stage2. It was also able to embed stage1. When it tried to install the rest, it errorred with something like:
....install /boot/grub/stage1 d (hd0) (hd0)1+16 p (hd0,0)/boot/grub/stage2 /boot/grub/menu.lst
Failed!
Error 22 : No such partition
.

This one took some time to get around as well. I almost opted to install Lilo but decided against it since I have begun to like Grub more. The way I got around this problem was to actually manually run the steps that Grub's setup command runs, with one addition:
embed /boot/grub/efs2_stage1_5 (hd0) - success!
install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd0) (hd0)1+16 p (hd0,0)/boot/grub/stage2 /boot/grub/menu.lst - success!

For whatever reason (I still haven't quite figured it out) you have to add the stage2 option. After this worked, I exited. I was time to reboot my server and cross my fingers for a login prompt.

8) Kernel Panic!! DAMMIT. I forgot about an initial ram disk image for my critical modules. Since Gentoo does not yet have mkinitrd in the portage tree, I decided to build in my array and filesystem support instead of modularizing them and manually installing mkinitrd. I recompiled the kernel with my changes, copied bzImage to my /boot and rebooted.

9) Kernel Panic! DAMMIT! DAMMIT! My above changes, while needed, had not made a difference in my desired outcome. This one took some time as well. Finally, after carefully reading the kernel panic message, I discovered that it was having some sort of problem accessing my root which I had set to /dev/cciss/disc0/part3 in my Grub menu.lst file. I dug through kernel docs to find a cciss.txt file that talks about adding the appropriate nodes under /dev. There is even a script located in the Documentation/ sub folder of the kernel source tree: mkdev.cciss. I made this baby executeable (chmod 744 mkdev.cciss) and ran it. After checking to see what it created, I noticed that the node structure now matched what I had seen mentioned before: /dev/cciss/cXdXpX. I went back to my menu.lst file and updated the root= parameter according to the new /dev structure and my partition setup:
root=/dev/cciss/c0d0p3.

Rebooted.

10) Hell yea. What I saw before me was a login prompt.

So that is about it. I then went abou emerging any other packages that I wanted.

Yes it was a long post, but if just one person benefits, my job here is done. :D

Wow.. 8O

This should probably go in the "Documentation" section. It's certainly written in that sort of form. Very good read though.. :)

I had a similar experience installing Linux on a DL380 - looks like AggieEmpeg did pretty much everything I did.

There's one thing I would add, though - I was starting with a completely empty DL380, no OS, no floppies, no CDs, no docs. I found a pile of useful downloads on the Compaq website. Start at http://www.compaq.com/support/files and pick your server from the menus. They have everything from BIOS updates, diag diskettes, to RPM's for the system management stuff. Yep, that's right, Linux RPMs, not just DOS/Win9x stuff.

I'm not sure how well the RPMs would work with Gentoo, but the hardware monitoring would be worth the effort, I think. I've got RedHat on my DL380, but only because I hadn't discovered Gentoo, and now it's becoming mission critical, darn it!, so I can't easily switch...

thanks for the info..
got me 90% of the way.
boots ok with the root=/dev/cciss/c1d0p1 reference in menu.lst
but complains when mounting with fstab.
modprobe cant load module /dev/cciss/c1d0p1
modprobe cant load module /dev/cciss/c1d0p2
modprobe cant load module /dev/cciss/c1d0p3

/ gets mounted as read only and df results in:
cannot read table of mounted file systems.

it seems at boot the structure is named c1d0p?
but after its booted up its all named /dev/cciss/disk0/part?

i know this coz because I can do:
mount /dev/cciss/disk0/part1 /boot

changing the entries in fstab to /dev/cciss/disk0/part?
doesnt fix the problem.

is there a parameter I can pass to the kernel to turn of devfs?
would this fix things?

thanks in advance!

M

just tried turning off devfs by passing devfs=nomount to kernel.
It didnt fix the problem.

I just got through installing Gentoo on a Compaq Proliant 1850R and had the same problem. The way it seems to work for me is to simply ignore the /dev/cciss/c1d0p1format and use /dev/cciss/disk0/part1 format all the way.

In other words, in /etc/fstab:

/dev/cciss/disc0/part4 / ext3 noatime 1 0
/dev/cciss/disc0/part1 /boot ext3 noatime 1 0
/dev/cciss/disc0/part2 none swap sw 1 0

and in /boot/grub/grub/conf:

title linux-smp-2.4.21
root (hd0,0)
kernel (hd0,0)/boot/bzImage-smp-2.4.21 root=/dev/cciss/disc0/part4


I actually have a Smart array, which shows up as /dev/ida, but I don't see why the above wouldn't work for /dev/cciss as well. Oh, btw, I compiled cpqarray into the kernel to avoid having to mess with loading modules. You should probably do the same for cciss.

PostPosted: Fri Jul 11, 2003 11:32 am    Post subject: mounting cciss filessystems on proliant dl380 Reply with quote

my /boot/grub/grub.conf looks like this:

title Gentoo
root (hd0,0)
kernel /bzImage root=/dev/cciss/c1d0p3

Changing 'root=...' to root=/dev/cciss/disk0/part3
results in a kernel panic because at boot time the structure is in the
c?d?p? format.
However, it makes no difference whether fstab contains the 'disk0/part?' format 'c?d?p?' it still mounts / as readonly and df results in a 'cannot read table table of mounted filesystems' Grrr!
And /dev/cciss/disk0/part1 will happily mount to /boot.
Why does root not mount properly from fstab, you'd think it'd mount ok as /dev/cciss/disk0/part3.

any other ideas?

afterthought:
How come, when booting off cd the c1d?p? exist in /mnt/gentoo/dev/cciss but they don't when booting off disk?
disk: ls /dev/cciss/ = disk0
cd: ls /mnt/gentoo/dev/cciss = c?d?p?...

I wanted to say a big THANK YOU to AggieEmpeg!
You saved me a lot of time and coffee...

I experienced EXACTLY the same problems and now i have a wonderfully running ;-) penguin on my smart array 5300 8-)

Again, thanx!

Why not post your fstab?

I used the /dev/cciss/cxdxpx scheme in my fstab, which looks like this:

Code:

/dev/cciss/c0d0p1       /boot           ext2            noauto,noatime          1 1
/dev/cciss/c0d0p5       /               reiserfs        noatime,notail          0 0
/dev/cciss/c0d0p6       /home           reiserfs        noatime,notail          0 0
/dev/cciss/c0d0p3       none            swap            sw                      0 0
[/i]

Hi,

I'm also using a Compaq DL 380 with a Compaq 431 Smart Array. I'm always using /dev/discs/...

Since the devfs introduction that's my preferred way to access my discs. No matter if it's IDE, SCSI, or some of the more exotic block devices like the mention RAID controllers, they just appear in /dev/discs/...

Just my 2 cents

PostPosted: Tue Aug 26, 2003 9:14 am    Post subject: DL360 with 'cpqarray' instead of 'cciss'? Reply with quote

has anyone here installed gentoo with the 1.4 install-cd on a compaq dl360 (first generation) with lilo as bootloader?

afaik it needs the module 'cpqarray' instead of 'cciss'.

the gentoo-disk recognises the array-controller at boottime and sees the logical drive at /dev/ida/disc0/disc resp. the partitions as /dev/ida/disc0/part*

then everything works well until i get to configure lilo. as soon as i type /sbin/lilo /dev/ida/disc0/* stops to exist. 'ls /dev/ida/' gives me lots of devices named 'c0d*'. /sbin/lilo doesn't accept /dev/ida/disc0/* as input in lilo.conf and i've to change it to /dev/ida/c0d* so that /sbin/lilo works.

i reboot the machine, lilo shows up, i choose the kernel to boot, it boots until a certain point where it says that i should enter a correct "root=" entry.

any idea?

cheers
javier

I'm installing 1.4-Release on Compaq Proliant 800 with SMART-2/DH RAID controller. I saw the problem where prior to chroot you have /dev/ida/disc0/ and after

chroot you have /dev/ida/c0d0. I tried to remedy this with the following command

prior to chroot-ing (from chapter 28 in the install guide)...

mount -o bind /dev /mnt/gentoo/dev

This succeeds in making the disk appear as /dev/ida/disc0/ after the chroot. I

ran genkernal again and noticed this...

cdimage / # cat /var/log/genkernel.log

Warning: sd_mod.o not found; skipping...
Warning: sg.o not found; skipping...
Warning: sr_mod.o not found; skipping...

I also did the stage2 thing in grub config.

grub> setup --stage2=/boot/grub/stage2 (hd0)

I have /boot/grub/grub.conf setup to provide me two boot options, (1) with

root=/dev/ida/disc0/part4 and (2) with root=/dev/ida/c0d0p4. Both of these

produce errors on boot:

(1)

Please append the correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00

(2)

For my 1st gen ML350 with Smart Array 221, I have everything in a JBOD config. Drives/partitions are under /dev/ida/disc0/partxx

had to do:

mount -o bind /dev /mnt/gentoo/dev" (outside the chroot.)
grub> root (hd0,0)
grub> setup --stage2=/boot/grub/stage2 (hd0)

For the grub.conf:

root=/dev/ida/disc0/part6

i got my proliant ml350 working the only thing i miss are the hardware monitor stuff at all.

anyone who has a hint for me how to install that stuff, maybe the suse enterprise server rpms work?

This reply doesn't address toskala's question (sorry about that).

I just wanted to thank AggieEmpeg for this post. With it, I was able to get Gento rocking on my HP DL360.

I was also able to follow the general idea of the post to install Gentoo on a Compaq Proliant 3000. The 3000 actually uses the cqparray module (and the logical drives show up as /dev/ida/disc#/), but otherwise it was still helpfull. The only thing I didn't have to do with the 3000 was run the makedev script for cqparray (I'm not even sure if there is one).

Anyway, I just wanted to post this info in case anyone else is trying to get Gentoo running on either of these machines.

I'm installing 1.4-Release on Compaq Proliant 800 with SMART-2/DH RAID controller. I saw the problem where prior to chroot you have /dev/ida/disc0/

I had the same exact problem this week. It turns out that the Compaq Array driver was built as a module by the genkernel tool. So I used the config genkernel created, but I changed from module to built-in, and that did the trick.

If you're looking for that option in make menuconfig, it's under Block Devices, Compaq Smart Array 5xxx Support.

If you are having problems trying this on a next-generation proliant (ala DL380 G3) this might help. I was having a kernel panic problem similar to below:

VFS: Mounted root (ext3 filesystem).
VFS: Cannot open root device "cciss/c0d0p3" or 68:03
Please append a correct "root=" boot option
Kernel panic: VFS: unable to mount root fs on 68:03

Well, with the newest generation of Proliant servers, there are 3 PCI slots, with the first 2 slots being hotplug PCI. In most cases, HP ships the proliants with the raid controller in PCI slot 1. In your kernel, you need to have Hotplug PCI support turned on with the Compaq Hotplug PCI driver compiled in (not as a module, same story with your cciss raid driver)

Hope this helps someone.

Cheers!

I've jsut worked through installing a handfull of DL360G3's at a customer site and decided to go down the bold and marvelous route of the 2.6 kernel and udev, with no devfs and here are my notes on it:

* The DL360G3 uses the cciss-driver

* In plain 2.4 kernels the devices (with devfs) will appear as /dev/cciss/discX/partX
* In plain 2.6 kernels the devices (with devfs) will appear as /dev/cciss/hostX/discX/partX
* In plain 2.6 kernels the devices (with udev) will appear as /dev/cciss/cXdXpX

Between the Gentoo 1.4 and LiveCD 2004.0 CDs there are some subtle differences, as one will end up with the /dev/cciss/host-scheme and the other skips the "host" directory denoting the controller number.

I have not yet found a way to get grub to play on 2.6 kernels, but I've successfully used the chroot environment of the 2004.0 LiveCD to install grub, and it does so without a hitch, no extra options (except one of the machines I bunged it and now it won't use the stage2-bit, and i get dropped into the grub-prompt on boot, reinstalling with the --stage2-option tomorrow will likely flush this problem).

Apart from that, the Gentoo 1.4 stage1 CDs cannot successfully be used to install these machines in my experience, as I get random machine hangs during load, but the 2004.0 LiveCD does it beautifully.

Apart from that, I'm not sure the disks are hotpluggable on the machine, or if it is Linux not liking it; I tried pulling a disk (mirrored disks) and it froze the OS, identical on 2.4 and 2.6.

A last thing, when using the 2004.0 LiveCD, boot it with this command line: "gentoo-nofb pci=noacpi", as the ACPI tables are not 100% according to neither 2.4 and 2.6.

Currently the machines are running 2.6.3-mm3 with a few small patches (one about sync hanging the machine) and has been running "emerge -e world" for a few days and they are behaving nicely so far.

Over the weekend I'm going to investigate the rpm's available at hp.com to see what fun bits might be gotten from these. Especially if turns up something to get environmental events form the boxes :)

Two more bits:

* When building from stage1, I've had problems with using "perl" in my USE-settings, so I added that after it came up and did an emerge -e world.

* As long as you're using the ~x86 keyword and /usr/src/linux points into a 2.6 kernel and you're running on 2.6, then doing a "emerge glibc" will nicely rebuild it and make it use NPTL, but with 2.4 kernel-headers, and all is well.

8) Kernel Panic!! DAMMIT. I forgot about an initial ram disk image for my critical modules. Since Gentoo does not yet have mkinitrd in the portage tree, I decided to build in my array and filesystem support instead of modularizing them and manually installing mkinitrd. I recompiled the kernel with my changes, copied bzImage to my /boot and rebooted.


AggieEmpeg, you say you had built in array and filesystem support, you mean you had a monolithic kernel?

And which changes you made in order to get init in place?

I'm in the very same situation and I'm just stuck ... monolithic kernel too .. should I switch to modules-based?

Thanks, powergen

Try making sure that you have SMART2 support enabled in your kernel (non-modular) and not just the Compaq Smart Array (cpqarray). We were able to get a DL360/G1 booting by enabling that option and specifying the root device as /dev/ida/disc0/part3 in the grub.conf and /etc/fstab.

Ditto for PL1600 & 3000 with Smart2* controllers. :D

To add my 2 cents.

Proliant 6500 with Smart-2/P.

Using cpqarray and mapping as:

/dev/ida/c0d0/disc
/dev/ida/c0d0/partX

I don't have a /dev/ida/discX

Also had to use the "mount -o bind /dev /mnt/gentoo/dev" to get grub to install from Universal LiveCD 2004.1.

My grub.conf (from using genkernel):

Code:

default 0
timeout 10
splashimage=(hd0,0)/grub/splash.xpm.gz

title=Gentoo Linux 2.6.5-r1
root (hd0,0)
kernel /kernel-2.6.5-gentoo-r1 root=/dev/ram0 init=/linuxrc real_root=/dev/ida/c0d0/part3 doscsi
initrd /initrd-2.6.5-gentoo-r1
