When you say it never used to work with sym2, you mean what? Didn't work at all, or just the prcoessor device at id 7? I think that most people using an MSA30 don't particularly care if they can't talk to the processor devices on that box, and are unaware of its existence. They can still access the disks just fine. (the MSA30 is a scsi JBOD, essentially.) Pretty much only HP's SNMP storage agents try to talk to that processor device, I think, so unless you're running them, you won't notice or care, so long as the disks are working. I think we originally saw the problem with an LSI card, but I forget exactly which one, it used the mptlinux driver, I think. -- steve -----Original Message----- From: Matthew Wilcox [mailto:matthew@xxxxxx] Sent: Thu 4/13/2006 10:24 AM To: Cameron, Steve Cc: linux-scsi@xxxxxxxxxxxxxxx Subject: Re: HBA self selection On Thu, Apr 13, 2006 at 09:58:50AM -0500, Cameron, Steve wrote: > There exist some target devices which depend on the adapter being > able to do self selection.

That means it never used to work with sym2 -- has anyone ever tested the MSA30 with an LSI 1010/896 card? I appreciate it's an U320 device, so that's probably not a common configuration. I can take the code out that prevents us talking to the bus; it's pretty much a one-liner: - if (sdev->id == np->myaddr) { - sym_xpt_done2(np, cmd, DID_NO_CONNECT); - return 0; - } but I'd like this change tested, if you wouldn't mind.
