Trying to install Fedora 13 on ML150G6, doesn't recognize the RAID Controller ...

Hello.

What can I do to install Fedora 13 or Suse 11 on a ML150G6?

The install process does not recognize the array controller. Only the independent disks are recognized.

Help me please ...

Re: Trying to install Fedora 13 on ML150G6, doesn't recognize the RAID Controller ...

so what do you mean by it recognizes the disk but not the controller ?

typically, if the disk was not configured by the controller you would not see any disk at all.

Unless the ML150 is different, you can interupt the boot just after raid initilization by hitting F8. the array configuration utility comes up and you can review or change the lun configuration.

once done, booting the install CD should proceed and show you the available storage and sizes.

give some example if this is not anywhere close to an answer to your question.

Among Generation 6 Proliant servers, there are a few low-end "entry-level" models that use a BIOS RAID instead of a real hardware RAID.

(BIOS RAID = a software RAID implementation where the RAID algorithms have been embedded in the system BIOS. When a 32/64-bit OS starts up, it must have the appropriate drivers installed to provide the RAID functionality: the actual hardware is essentially just a multi-channel disk controller with no significant caching or other RAID hardware acceleration features.)

If your ML150 G6's RAID controller is "SmartArray B110i", then it's a BIOS RAID. It is compatible with the real SmartArray controllers, though: it can be controlled with "hpacucli", and the disks apparently can be moved to a real hardware SmartArray without losing data if desired.

There is a downloadable driver (hpahcisr) for RHEL and SuSE, but not for Fedora.

If you need to use Fedora and don't plan to move the disks from this system to a more advanced model in the future, you might as well use Linux's software RAID instead: since the processing is done on the system CPU anyway, there should be no significant difference in performance.
