I have IBM servers with VMWARE ESX 4.1, I use the Brocade HBA 415, is this true HBA does not support if connected with a direct-attached storage?
Because I try to connect my servers with EMC storage, the result ... if I direct-attach the HBA, wwn not detected in EMC storage, but if I use san switches, everything is running well.
Does anyone have the same problem, and have found a way out?
Thanks & Regards,

Yes, and some EMC Array cannot be used as DAS because the Controller Microcode not support those feature.

I already try to change the hba card (using emulex LPe11000) and HBA wwn can detect on the EMC Storage (CX4-120).
I think it means no problem with the EMC storage.
so far it means the brocade 415 HBA dosn't support for direct attach.

Have you try with another Boot Code and Firmware for the Brocade HBA ?
In HBA Bios Mode, what kind of feature ara available you can set ?
e.g. Point-to-Point, etc...

Yes, initially I used the driver for ESX 4.0 (before the release of firmware for ESX 4.1), after the firmware for the ESX 4.1 release, I uinstall my old firmware and replace with the newest firmware (firmware for esx 4.1), but ... wwn still can not be detected.
I also have to change boot code settings via BCU command BCU, and I set topology using "auto" as well as "point-to-point" but wwn still not detected on EMC storage.
# bcu port - topology 1 / 0 auto
# bcu port - topology 1 / 0 p2p

was work this Driver and the OLD FW with the Array as DAS ?
I'll try to find more and post here.

I actually ran into this same issue today, and feel a lot better that I've come across this thread. I have a new Dell R710 server running VSphere 4.1 that I wanted to direct-attach to an EMC Clariion CX700. No matter what I did, I could not get the CX700 to see the HBAs. After posting in the VMware forums, someone informed me that direct-attached is not supported, only 'fibre channel switched' mode. So I'm now purchasing a cheap switch on EBay so I can get up and running. Funny how its the little details that always hold you up in the end!
