hp netserver lh 3/lh 3r and SuSe lInux 9.1

[Alan Civita]

Hello i'd like to install Suse Linux
Professional 9.1 on our HP Netserver LH3, but the operating system does
not recognize the RAID Disck controller on board. Can you tell please is
there are some drivers for linux for the RAID device? Thank you very
much in advance.

Hi Alan,

Hi as i can see
is:
MegaRAID LD0 RAID5 26031R
thank you

[xyko_1]

Alan,
Do you have another operating system (ie. Windows) running on that server ?
If not, did you configure your raid controller before atempting to install SuSe ?
When you try to install SuSe, the instalation process don't recognise any disk ?

As far as I know MegaRaid controllers are fully suported on Linux for a long time.

Please, go to http://www.oldham.gov.uk/mccall/linux/
and see if it helps you.

Regards,
Xyko

well the situation is very strange..
1 year ago i've installed (and now is running on) SuSe linux enterprise server 8...
Now i'd to install on the same machine the Linux Professional 9.1 due to some licencing problems..i've tried to install also fedora ..but nothing ..no distribution seems to recognize the RAID controller..

Please,
attach a file with the output of :

dmesg
cat /proc/pci
cat /proc/scsi/scsi
lsmod
/etc/modules.conf

Meanwhile, verify if there is a newer firmware for the controller.

hi..

here attached the informations required

Alan,

Your megaraid is a LSI one and I think there is a problem in SuSe 9.1 to identify this controller on boot.

Download instructions and a new driver on http://www.lsilogic.com/downloads/license.do?id=2000&did=7776&pid=2409

and please give me news about your progress.

Good luck.
Xyko

Alan,

Have you had any success with the drivers from LSI for Suse 9.1?

I have the same problem, and have downloaded the drivers but not sure how to make the disk with the drivers. Can you help me?

Thanks.

Hi
i'm near the solution :)
Try to follow theese steps:
Boot from Cd
Choose manual installation
Go to Load Kernel Module--->SCSI Module
and select megaraid module (the megaraid is written on the right part)
Go back and select--Start instalaltion

This should work.

After that i've encountered other problems:
1) After the installation, on the first reboot, the system didn't recognize the SCSI disk anymore..so you need:
Boot from Cd
Choose manual installation
Go to Load Kernel Module--->SCSI Module
and select megaraid module (the megaraid is written on the right part)
Go back to Start Installation and select
Start rescue system (or something like that)
Login as root...
modifiy the /etc/fstab (vi /etc/fstab) and put your entry for the HD /dev/sda3 /suse reiserfs defaults 1 1
and save.
create the /suse (or a name as you prefer) and mount here the HD.. mount /dev/sda3
make a chroot..chroot /suse..
Now mount any other partition if not on the sda3, like /boot etc etc...
Now Take a look at /etc/sysconfig/kernel
and check that:
INITRD_MODULES="megaraid reiserfs".
If megaraid is not present..please add it.
After that save the file and make mk_initrd
and reboot..it should be ok.
Tha real problem is if you lunch Yast Online Update and upgrade the kernel...the problem is the same...but in this case i wasn't able to solve it ..with the procedure below...i'n still on it.

[Alan Civita]

Hi i've solved it ..by loading not the megaraid driver but the megaraid-old
Try this if yopu encountered problems
Bye

Hello, i have a netserver lh3 with fedora core 2 installed. When i installed it i had no problem and the hard disk was recognized directly by the installation program. Now i've tried to install fedora core 3 in the same server but the installation program doesn`t recognize the hard disk. Could you be so kind to help me?.
Thanks in advance.

[Alan Civita]

hi..i can say i've solved the problem with Suse by using the megaraid-old module

[Jacobo_3]

OK, but i`m very inexpert and i don`t know how to load a module at boot time. I know tha i can do it but i don`t now how to do it neither when can i get the proper module. I have fedora core 2 installed and running ok. how can i get then proper module and load it at boot time during the instalation of fedora core 3?
I would be very grateful if you could help me.

A lot of thanks in advance.

[Alan Civita]

hi..i'll post you the procedure tomorrow morning..now i have to go

[Jacobo_3]

OK. Thank you very much.

[Jacobo_3]

Hi Alan,

do you remenber my question? Thank's.
I'm using Fedora Core2 and all is going fine but i'm not able to install Fedora Core 3.

Could you tell me how to load the mergaraid-old driver instead the megaraid?

Thank you.

Jacobo.

[Alan Civita]

hi
sorry ..but i'm really busy at the moment..
you should at first enter in a safe mode shell..
the you can read the pprevious answers to this post..where i've sugested how to edit the fstab..load the module etc..sorry i missunderstood...on fedora i don't know how works the setup system...
on suse if you abort the setup you are redirected to a text mode setup..where you can load kernel modules another things like that..
try look at this and let me know
