FreeNAS not seeing drives connected to RAID CARD

[alkyred]

I am building a FreeNAS server using a 24 bay SuperMicro server with an LSI RAID card. I have raided the first two drives RAID 1 and then installed FreeNAS on that one Virtual Drive. I thought that once I had installed the FreeNAS OS I would log in the FreeNAS console and then create my storage using the other 22 drives.

The problem is that I don't see any drives listed to build a storage pool.

Any help\suggestion would be appreciated.

Thanks

You don't use raid cards with freenas you need to flash the card into IT mode. Do a search there are thousands of threads about the topic.

You need a HBA or a raid card flashed to it mode for freenas

FreeNAS was designed to run from flash storage don't waste your hdds and no raid controller. You need to let FreeNAS control the drives directly. Look over the documentation

Thanks for the responses.

So now I have additional questions. I am going to be using this server as our NAS to handle all our companies storage needs for iscsi xenserver storage, and File storage replacing our file servers. I am going to have 2 of these servers Primary and a Live Back. I am a creature of habit so now my thoughts are to move the two drives that have the OS installed to the motherboard on-board raid controller so I have the OS Raid 1 and then use the entire 24 bays for storage. Or is it recommended to just leave the OS on a single non raided drive.

Thoughts?

Dont use the onboard raid.
Plug the 2 drives to the onboard Controller and let FN mirror your boot devices

Nope.. Forget the Hardware Raid altogether. Just select the two drives during the install and FreeNAS will handle Mirroring them for you. I know its difficult to get your thoughts away from Hardware Raid (took me a while to wrap my head around it at first), but with FreeNAS you want/need to.

Okay I think this will be my last question.

I can flash the LSI to IT mode or I can buy a new HBA card. Is there any advantage to buying an HBA vs. flashing the Raid card? Speaking to performance that is.

What LSI is it (Make/Model or Chipset)? Depending on the model, you may or may not be able to flash it to IT Mode.

Not really, unless you are trying to "go big" and do a 12Gbs HBA, most of them are 6Gbs and will be just fine.

I hope this isn't your last question, you have so much more to learn. Start a thread with your hardware spec and workflow. You will gets lots of advice like you should use mirrors and max out your memory. With iscsi you should try to keep your pool 50% free.
