Slackware 12 and IBM ServeRAID
 
Hi all,

I like to know if the IBM ServeRAID adapters are supported in Slackware 12 and in which kernel.

I have an old IBM x330 (2 CPU box with RAID1 disks). All disks are configured in the RAID controller to act as one disk but Slackware can 't find them. The only device he detects is the CD-ROM drive (which is IDE).

With Slackware 11 I had the similar problem, but it worked if I installed huge26.s in stead of raid.s.

Does anyone have any tips how to get things running?

Thanks!

i would grab lastest kernel from kernel.org and use the config file from the stock hugh-smp-2.6.21.5 kernel in slack 12, and look through the options for raid controllers

I have not tried with Slackware 12.0 yet, but IBM ServeRAID adapters are supported by the "ips" driver.
This driver is built into the hugesmp kernel so if you have configured your ServerRAID card with a logical volume consisting of the physical disks in your server - using IBM's support CD - then the default Slackware install CD kernel should pickup the logical volume as /dev/sda .

Yes, I have configured a logical volume on the ServeRaid adapters with the ServeGuide CD's.

The RAID controller is identified as an Adaptec i160.

But when he tries to identify the physical volumes (I guess he see the logical configured volume must be transparent, so the two disks in RAID1 is the same one physical disk), he can find anything.

Code:

Creating /dev/mapper/control character device with major:10 minor:62
reading all physical volumes...

no volume groups found


And then I am stuck....

Maybe you can look up in the documentation that comes with your IBM server which linux kernel driver supports this one.

This has nothing to do with RAID logical volumes at all. The Slackware boot process tries to initialize any LVM volumes. LVM is "Logical Volume Manager" which is a software solution to (amongst others) present several physical volumes as a single logical volume.

Okay, thanks for your help already!

So, what do you suggest I should do?
- look for a kernel driver? (where?) and compile it myself (as a Linux newbie?)
- let go Slackware 12 and install Slackwere 11 with the huge26 kernel (it works but do I have SMP support for my 2 CPU's)?

Muchos gracias!

If it worked with Slackware 11.0 and the huge.s kernel, it will certainly work with Slackware 12.0 and the (default) hugesmp.s kernel.
Plus, with that hugesmp.s kernel your dual CPU will be supported out of the box.

Hey guys, this sound interesting :) I got a primergon rx300 s3 that i just would love to install Slackware on. The problem is that i also want to use XEN ( and hardware Raid ) of course. Now, with it (cmpta) comes some CD:s, two which are called driver cd:s. As far as I understood those create some kind of buffert between the computer and the OS. I don't want to many 'layers' but i'm not sure it creates that or if it just initiate and then 'walks back', so to speak. Also i would love to have hardware Raid installed on it,the drivers that comes with it though only refer to Red Hat 5 and Suse. But I wan't my Slackware !!!
Also it uses a quadra core Intel CPU which may not be implemented in the linux kernel? Or am i bicycling in the blue younder again ::))

Any ideas ?

Btw: 'Plus, with that hugesmp.s kernel your dual CPU will be supported out of the box.' Is that sooo :)I would luv that..

I read somewhere that the huge kernel gave problems, but that's wrong then Alien Bob? Or??

Okay guys,

The cfdisk /dev/sda did the trick! Thanks!
