Raid on DL180 G6 invisible to RHEL5
 

Hi,

I have a new DL180 G6 server with 4 x 500Gb HDD's. I have configured this into a 1+0 raid array and the configuration utility reports 1Tb space as expected.

When I boot off of the RHEL 5 DVD the 4 HDD's are there, not my array, Anyone know what I am doing wrong?

Tks,
Owen.

Have you entered the "Advanced Storage Configuration" in Disk Druid ?
Is "Disable dmraid device" selected ?

I haven't been using disk druid, Is this a boot option on the Proliant?

Please explain what you are trying to do.

If you are booting from the RHEL dvd, then presumably you are doing so to install the operating system. I assumed this because you said it was a new server and you had just created the raid array, so it should be empty.

Disk Druid is the partitioning editor which is part of the RHEL install process.

What storage controller are you using? I looked at the model's specs and saw three options:
Smart Array B110i SATA RAID
Smart Array P212
Smart Array P410
(from http://h10010.www1.hp.com/wwpc/us/en...1-3884339.html).

One thing to note is that some storage controllers require a special software component a-la the old winmodems (thus requiring windows). I ran into this some time ago with a Dell Precision workstation. There were BIOS options for enabling the RAID, but Linux just did not see it. I used the mdraid option instead and have been pretty happy with it!

Check your storage controller and see if this is the case.

The only option under the advanced section is to add an iSCSI drive.

I have followed the instructions here

http://h20000.www2.hp.com/bc/docs/su.../c01706551.pdf

to enable the controller and the controllers post reports 1 logical volume but still Anaconda is showing 4 drives in the partition setup screens (Disk Druid?).

Rds,
Owen.

According to the document you linked, you need to install device drivers for linux to recognise the array. So they will not be available during an install from the RHEL dvd.

Read the section on installing device drivers.

Also read this, which will allow you to force the rhel installer to look for the drivers :

(E.1.3. Using a Driver Image During Installation)

*edit*
Just saw your previous post now... will have a look

I'm pretty sure that is for software raid only,

TITLE: HP Smart Array B110i SATA RAID Controller (AMD64/EM64T) Driver for Red Hat Enterprise Linux 5 (AMD64/EM64T)

VERSION: 1.2.1-3

LANGUAGE: English

CATEGORY: Storage Controllers

DIVISION: N/A

OPERATING SYSTEM: Red Hat Enterprise Linux 5 (AMD64/EM64T)

ELECTRONIC DISTRIBUTION ALLOWED: Yes

DESCRIPTION:

This RPM is used to provide binary driver modules that have been pre-built
for Red Hat Enterprise Linux 5 to enable software RAID for the embedded ICH10R controller.
This RPM provides a customer friendly approach to install a pre-built
binary driver.

You don't need specific drivers for software raid, that's why it's "software" raid.
I think the software they refer to there is the raid management software that actually runs the card, not software for the OS.

The card needs software to run, regardless of the operating system. Without that software, the OS has nothing to access.

To be honest, if rhel is not seeing the array as one disk, then maybe it's because it has no drivers to access it as a disk.
