 |

That's a great link too... you've got all the information, thanks!!
I will use udev on this system and I'll be sure to post back here on my experiences with it (once I figure it all out).
THanks again for all your help Brain!!

Just for reference gentoo put everything in /dev/disks
I used the compaq smart array partitionig tool, so my disks appeared as
| Code: | /dev/disks/disk0/disk
/dev/disks/disk1/disk
/dev/disks/disk2/disk
/dev/disks/disk3/disk |
I'm using a 2004.1 universal live cd and only needed to
Seems quite simple now (after a LONG time buggereing around trying everything else on the planet)...
I do however have one issue. The damn thing hangs when i hit numlock!
Oh and what the hell does the remote insigt thing do, and will it work with linux? at the mo it's on a shelf untill i get the restof the system vaguely happy |

Compaq's remote insight is kind of a all-around hardware monitoring tool used to watch the server from afar. It needs drivers running on the OS though. HP (they ate Compaq) has drivers for Red Hat and I even believe that someone tried an ebuild but I could never get it to work. I think it needed a ton of outdated libraries and such.

It is pretty cool. It'll tell you if drives are spinning below spec, which parts of the server may be overheating, etc. We run gentoo here at work and spent a good deal of time trying to hack it to work but to no avail. Worth a try I guess.
You do mean the "Remote Insight" software though not an ILO board, right?

Err I may be missinformed, I have a full lenght PCI card with 2 RJ45s a video port and a PS2 keyboard port on the outside. Inside it has a 7.2 volt NimH battery, a PCMCIA 33k modem and a whole host of other chips on it.
It says Series EVB N119 on the back, and Remote insight board on the front.
The graphics, keyboard and lan work trhough the board when it's plugged in, but at the moment it's on a shelf
Also I AM A MUPPET
I mis-read my info on the compaq array configuration software, managed to partition the scsi array into 4 virtual disks, and tried to use them as partitions. Alarm bells only rang when i got to installing grub and i realised i had hd0, hd1, hd2 and hd3 but no partitions on them!!!
Am about to fix and then rebuild. |

AHhh... I have a few of those as well. The mystery card is an iLO, or as Compaq called it, an "Integrated Lights Out" board. Those are kind of handy. The idea of them is that you can have the ability to see everything that's happening on the server--POST, kernel panic, what have you-- remotely. For example, you have the ability to physically power the server off and on if Linux bombed as if you were in front of it. If you have it, you might as well put it in.
It operates independantly OS, sort of like a PC on a board until the OS comes up and starts spitting video I/O at it. It gets assigned an IP address separate from the server and you access it that way. The newer ones need no drivers from the OS, and I'm almost positive the older ones work the same way.
They were $2000 options back in the day!

Waaa
Ok, this time the thing is partitioned properly ( I think) and i get once again to the very last bit, makeing grub work, and it's not playing ball.
My partitions are set up as
| Code: |
/dev/ida/c0d0/part1 is /boot ext2
/dev/ida/c0d0/part2 is swap
/dev/ida/c0d0/part3 is / reiserfs
/dev/ida/c0d0/part3 is /home reiserfs
|
They also show up as /dev/disks/disk0/part[1..4]
Anyway, I'm trying the following:
| Code: |
livecd / # grub
grub> root (hd0,0)
Filesystem is ext2fs, partition type 0x83
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... no
Error 15: File not found
|
This is most definately not good 
The good news is the iLO is working after a little persuasion |

Just to save someone some time, I hope, when using udev instead of devfs the device names change. The table below lists all three...
| Code: |
/dev/sda = /dev/ida/c0d0/disc = /dev/ida/c0d0
/dev/sda1 = /dev/ida/c0d0/part1 = /dev/ida/c0d0p1
/dev/sda2 = /dev/ida/c0d0/part2 = /dev/ida/c0d0p2
/dev/sdb1 = /dev/ida/c0d1/part1 = /dev/ida/c0d1p1
|
Hope this helps someone, even if it is just me when I forget and come searching the forums! |

| Posted: Mon Jan 03, 2005 9:34 pm Post subject: when using the 2.6 kernel |
|
|
I had problems getting grub to recognize my drives. To correct the problem I created the file /boot/grub/device.map with the contents
(hd0) /dev/ida/c0d0
I launched grub using the --device-map option
> grub --device-map=/boot/grub/device.map
grub was then able to find my hard drives.
Adjust the entries in the device.map file to suit your setup
The disk naming format seems to have stabilized in the 2.6 kernel. I used the /dev/ida/cXdXpX names in /etc/fstab and grub.conf |

(hd0) /dev/cciss/c0d1 // main scsi
(hd0,0) /dev/cciss/c0d1p1 //boot
and # grub --device-map=/boot/grub/device.map
but I get this error
device.map error 2: no close parenthesis found.
what to do ! it's 3rd installing gentoo on Compaq Proliant ML350 with smart array 5300 |

A couple of questions come to mind...
1. c0d1 indicates the first array controller (c0) and the second array (d1) does your device have multiple arrays assigned? If this is indeed the second arry you should probably assign it to (hd1) in your device.map file.
2. I don't think the second line is needed. (the device.map file is for assiging drive references, not partition info). When you enter the grub shell to do the final configuration you'll specify the partition as follows
(hd0,0) = first disk, first partition
(hd0,1) = first disk, second partition
(hd1,0) = second disk first partition
(hd1,1) = secodn disk, second partition.
3. There is a howto that describes installing gentoo on a dl380 using the smart 5300 card. You might give that a try, especially the manual config of grub. The howto is here. Look at Step 7.
You might also try lilo. I used lilo to get my system to boot its own kernel and then switched to grub so I wouldn't have to keep using the gentoo install cd and chrooting. |

ak7: yep the second line was not necessary
success installing and booting from grub.
now I get this error
| Quote: | VFS: Cannot open root device "cciss/c0d0p3" or 68:05

Kernel panic: VFS: Unable to mount root fs on 68:05 |
quoted:
"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. "
have run mkdev.cciss and it has generated the /dev/cciss/cXdXpX structure.
but still kernel panic VFS |

What does your grub.conf file look like?
Mine looks like this (Proliant 2500 with the smart 2P controller)
| Code: | default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.9-gentoo-r9-mem
root (hd0,0)
kernel (hd0,0)/kernel-2.6.9-gentoo-r9-mem root=/dev/ida/c0d0p4 memmap=exactmap memmap=640k@0 memmap=1023M@1M
title=Gentoo Linux 2.6.9-gentoo-r9
root (hd0,0)
kernel (hd0,0)/kernel-2.6.9-gentoo-r9 root=/dev/ida/c0d0p4 memmap=exactmap memmap=640k@0 memmap=1023M@1M
title=Compaq Utilities Partition
rootnoverify (hd0,2)
chainloader +1
|
The memmap boot parameter is required to correct a know memeory reporting issue with older compaq hardware. The issue was corrected when the P3 based servers were released.
The two kernels defined have different memory options (testing performance). I can also invoke the smart start utilities from the compaq utilities partition.
It looks like your path to the root partition is incomplete (missing the /dev) so you may want to try changing your grub.conf file. |

Partition your disks as you feel fit. The cpqarray driver has a different naming scheme for the disk devices than plain-old SCSI. The table below shows the equivalents.
| Code: |
"/dev/sda" = /dev/ida/c0d0/disc
"/dev/sda1" = /dev/ida/c0d0/part1
"/dev/sda2" = /dev/ida/c0d0/part2
"/dev/sdb1" = /dev/ida/c0d1/part1
...etc.
|
Make sure you write down your partition mappings (i.e. /dev/ida/c0d0/part2 = swap /dev/ida/c0d0/part1 = /boot). You'll need them later.
|
Hi, maybe a stupid question, but, if I don't have anything in /dev like 'ida' and so long, do I have to create it by myself?
If so, what options should mknod have?
Thanks in advance.

Is that using devfs or udev? I have a feeling they will be different again if you switch. |

I am using this howto to put gentoo on a proliant 800, dual 200mhz p-pro, 128mb ram, 3x 9gb scsd (raid 5)
everything is fine up until installing grub
| brain wrote: | Step 6 - Grub
Now the fun part. Follow the installation guide for installing grub. When you get to this part:
| Code: | grub> root (hd0,0)
grub> setup (hd0)
grub> quit |
Replace the "setup" line with:
| Code: | | setup --stage2=/boot/grub/stage2 (hd0) |
I believe the reason this is necessary is that Grub doesn't understand the /dev/ida/* disk setup and needs to be forced to know where to get the stage2 files from. |
After the first line, I see:
| Code: |
grub> root (hd0,0)
Error 21: Selected disk does not exist
grub> |
/proc/mounts was copied over to /etc/mtab. shouldn't matter, but I'm installing remotely via ssh.
anyideas what I should do to get it to see the boot partition?

Assuming I can manually edit it, is the correct format:

That did work, but i had to use:
