Hi all,

Centos 5.6 doesn't detect any disks connected to an Adaptec 6405 RAID Controller. The hardware isn't brand new to the market, so what might be the issue here? It seems, that the driver is missing for that particular card.

I don't know about that particular device, but I've seen RAID controllers where you had to run their bios setup utility to add disks and create volumes even if you only want a single disk per volume. The OS only sees the volumes as logical drives. Or have you already done that step?

I have and array setup in the controlers BIOS. What i need to do is to install centos on the logical volume. Still, Centos 5.6 seems not to have any drivers for Adaptec 6405.

Maybe try Adaptec drivers? http://www.adaptec.com/en-us/downloads/rh/rhel_5/productid=sas-6405&dn=a...

I have tried adaptec drivers on both 5.5 and 5.6 using "linux dd" option. Still the system doesnt recognize the device.

That doesn't sound right. Are you sure it works?

I am sure it doesn't. I have booted 5.5 and 5.6 in linux dd mode. Then I have loaded the drivers from: aacraid-driverdisk-CentOS.iso . Still, the installer sees no hard disk. I have read somewhere, that the adaptec driver to that controller works only with Centos 5.4, but i need a newer version of Centos. Maybe using drivers from RHEL 5 / 6 would be a better solution here?

Thanks for Your help, mjb

binary drivers are *very* kernel version specific.

you could install centos 5.4 with those drivers, then yum update everything *but* the kernel

Ok, I'll give it a try. Thanks.

You could also ask on the elrepo mailinglist. There was a request not too long ago.

http://lists.elrepo.org/pipermail/elrepo/2011-April/000637.html

So maybe you can install centos 5.4, then install their newer aacraid driver and then you can update the kernel as well...

As Rainer said, this is best discussed on the ELRepo mailing list, but ...

There is a good chance that kmod-aacraid from ELRepo works on the Adaptec RAID in question. To confirm this, it will be helpful to get the hardware fingerprint.

# lspci | grep -i raid

will show a line similar to:

01:00.0 RAID bus controller: Adaptec AAC-RAID

Then running this:

lspci -n | grep 01:00.0

will display the vendor:device ID pairing.

Ok. I'll give it a try. Is there an easy way to install the driver during Centos install process. All disks in my server are connected to that Adaptec card.

You might have to install 5.4 with the vendor's driver disk, then the kmod driver, then 'yum update' to get to 5.6. Just make sure the initial working kernel isn't deleted until you are sure you can boot the update. I think the default is to always keep 2, one of which is the one running during the update. Or maybe it is the running copy plus the 2 latest.

<snip> I'm not quite clear on your answer: are you saying that you created logical RAID volumes, added the physical drives to it, and initialized each volume?
