RAID setup - Redhat 7.3 / 8.0

Martin Glazer — Fri, 27 Dec 2002 22:01:18 GMT

I have a ML310 with the ATA Raid controller, 4 x 80Gb HDD's setup under the raid controller to do Raid 1 (ie. 2 mirrored drives of 80Gb each).

On bootup I see the 2 Raid drives, but when attempting to install Redhat 7.3 / 8.0, Linux sees each individual drive and not the combined Raid drives.

Do I have to use Linux's software raid to install - the raid controller seems redundent then, or am I missing something in the install.

I have tried using the driver disk provided by Compaq, but still get the same results.

Any suggestions?

Hi Martin,

You do not need to setup software RAID. Hardware should be fine.

To have it work properly you may need the driver disk provided by Compaq/Hp :

Good luck.

The gentleman is correct.

If you want to do software raid for some reason, its done from the disk druid stage of setup.

I've done it, and have a printed document at home if you want me to look at it and find the url.

Identify yourself on the subject line.

btw, I'm running a web hosting business, including mail on Red Hat 7.3. The production server does use software raid.

Martin,

In RH, you need to create a RAID drive in disk druid and then specify which individual drives are part of it.

I had difficulties with this on one of my HP systems. I finally had to remove the RAID card, then everything worked fine.

Thanks for all the responses -

I managed to find a raid driver on the Compaq / HP site and install Redhat 7.3 using the raid featurees of the onboard controller. I did not use the linux s/w raid as I was also going to try and attempt to use LVM (Logical Volume Management).

Problem I'm facing now is the driver is only for 1 specific version of the Redhat linux kernel and I can't upgarde the kernel (bug fixes) at all unless I find the source for the raid module. Anyone know where I can find it?
