X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 30 Mar 2011 13:54:14 -0000 Hello. I have IBM blade, which is connected to EMC Clarion disk storage (2 FC adapters connected to 2 FC switches, so system sees 4 paths to storage). One lun is provided to the system. The problem is that FreeBSD doesn't boot randomly (at least 1 attempt from 5 boots is unsuccessful). The blade stalls and I see only blank screen. I've tried other operating systems - OpenIndiana b148 and Ubuntu 10.10 - each of them has booted perfectly 10 times without any issues. I don't see any messages from boot1 stage and system is logged in to EMC storage with only one path. When the system boots successfully, I can see on EMC Clarion that it is connected with all paths. I've tried to use boot0 from CURRENT - results are the same (boot fails randomly). How can I debug this issue?
