Fedora Core 10 driver help

[raidstorage]

Need some Fedora core 10 guidance. I am not a Linux person.

I have 2 HP DL580 running Fedora Core 10 and we are adding 1 QLE2462 to each servers with a 4GB External Fibre RAID enclosure w/4.2TB useable, 300GB SAS drives in a raid 6
One of HP server already has the OS loaded.
The other I will be loading the OS from scratch.

1. Does Fedora 10 come with drivers pre-loaded?
2. If not do I just download the latest from QLogic page using the RH driver? What drive should I use?
3. The other server we are loading from scratch. If we have the HBA in the server will it automatically load the driver during the loading process (post)? Somebody told me yes?
4. Does Fedora support over 2TB limitation? If it doesn't do I have to edit anything in the kernel to have it support over 2TB? Or is automatic? I think as long as it supports 64-bit LBA addressing, I should be ok and the kernel is above 2.6.

I think I can run # dmesg | less to verify.

5. Multiple LUN support? If I have multiply LUN's will the OS see all or will it only see LUN 0 by default?

Lost sole :)

Doug. Fedora 10 hasn't even been released yet. It's still in Alpha stage so you're running a test release on production servers. Maybe you should get to downloading Fedora 9 for the time being.

Moved to Alpha-Beta (Fedora 10 Only) !

Hi Glen thank you for the reply.
It was one of my customers wanted Ferdora 10.
If i use fedora 9 what about my questions on the drives?
Are they pre-loaded? If i go to Qlogic's web page they dont have Fedora. I believe Fedora is basiclly RH v4?
If i jsut install the HBA with the Os automaticly detect the card?
thanks again Glen.

Let me be honest. This server stuff is way over my head. I thought I'd caution you on using an Alpha release of Fedora just the same. The QLE2462 is a relatively new PCI-E device? Might be hard to find Linux drivers for it. Maybe something from Redhat? And now that I've mentioned Redhat, isn't it about $80 to actually purchase Redhat Enterprise Linux? Wouldn't that be a far better option for your client? I'm assuming this is a production environment in a corporate setting and as such maybe there's a few dollars available? You'd get Redhat support, to a point, and may even get help on building your own custom drivers if it came down to that.

I guess the big question with Fedora 9 or 10 support a Qlogic QLE2462 fibre cahnnel HBA (4GB)?
I would think it is supported.

I used to work with hbas on linux.

Fedora won't automatically load the correct driver, it's always better to install the driver from Qlogic. Qlogic provides hba drivers on their website (use the driver for RedHat) and the readme file is easy to follow.

3 years ago, the linux kernel shows all LUNs that was assigned to the hba; even if the LUN is a duplicate from a different hba port or network path, so you might see a lot more LUNs than you think you have. I haven't touched hba for awhile now, but I think Qlogic's software can display the LUNs and the topologies.

I am not sure about the 4 TB support though.
