linux + megaraid broken

Harry Stangel — Fri, 27 Aug 2004 19:47:41 GMT

I attempted to install Fedora 2 (2.6 kernel) on our latest LH6000r, but the NetRAID arrays were not automatically detected. I hand-selected the megaraid driver, but later the install failed with 'no disks found'.

So I installed RedHat 8 (2.4 kernel) with no problems; everything was auto-detected and the megaraid driver (v1.17a) works like a charm.

An earlier post showed someone having the same problem with SuSe 9, while SuSe 7 worked fine.

How can I get Fedora/megaraid/LH6000r to play nicely?

Best,
Harry

U can download the drivers from HP site and load the driver manually.Don't allow fedora to use the built in driver,This would solve the problem

Only problem is HP's drivers are for older kernels.

The install succeeded when I passed these boot parameters at the Fedora install startup screen:

linux acpi=off apm=off

Apparently the megaraid driver v2.x has problems living with power management functions.

Are you using a NetRAID 4M controller?

If so, you could try using the aacraid module. I use this on the system I have in the test-bed (running SuSE though, not RH).

The Megaraid module seems to have developed a problem - though the question really stems back to whether it was more forgiving in the earlier versions, and less so now as things are tidied up. Many of the problems used to be caused by badly behaving SCSI controllers. Its a little better now, but older controllers are still out there and causing the odd issue.

Anyway, if you do a modinfo on the aacraid module, you'll see a list of some of the comtrollers it supports.

I had the same issue with power management, and used the same method you did. Never did get the megariad module to see my controller though.

Pretty bad when you have to answer your own tech support question, eh?

I found out that by optioning out the acpi and apm that it will also work with Fedora 4, but it keeps shutting down abnormally before it can install. Any tips?
