ATTO SCSI 10.2.4 Server and external RAID5 can anyone fix ?

[beenie]

I’ve posted this is various places… but no one knows the answer.. so here goes again….

I now have OSX Server 10.2.4 installed on a G4-400.

I have an Atto UL3S card with lastest firmware and drivers installed.

This works fine with an external Scsi hard drive and a Sony AIT2 drive and a Sony AIT2 4 Tape loader.

With Atto Express PCI ‘tool’ i can see the card and the drivers loaded and any of the above devices when i connect them.

But when I connect my Raid5, I can see the card and the drivers are loaded (I have access to the NVRAM setting on each port)

but no raid.

The raid is configured on ID4 LUN 1.

I can connect to this raid in OS9, but only by using the atto ‘removable drive’ extention. Without this, once again I cannot see or mount the raid. What does this extension do that the drivers in OSX don’t ???

I wonder if there is some setting written to the disk that could effect it mounting. I note that the driver on the raid is ATTO SM4.3 rather than Apples own scsi manager, would this cause it to fail?

There is a setting to ‘ignor’ LUNS but this is “not available under OSX” could this be the issue???

I’m not alone in this issue…

Here he says to solve this issue he has to map the raid to LUN0, this is not something that I can do as our raid has dual controllers and is a split volume. thus one controller is on ID0, LUN0 the other is on ID4, LUN1

So anyone… any ideas?

tia.
