X-BeenThere: freebsd-scsi@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: SCSI subsystem List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 28 Feb 2011 10:37:11 -0000 Hello SCSI list. Im trying to solve some problems we have with a FreeBSD 7.3 and a Dell MD3000i. The main problem seem to be that FreeBSD does not have support for multipath? We get nasty crashes sometimes and it seems to be during a switchover/failover event on the storage. I have seen some discussions about this with Danny and his great work bringing iSCSI initiator to FreeBSD. But i have not really been able to find that the iSCSI driver now supports it or if it is coming soon? Or if there are any other ways to avoid system crashes when the storage is switching between it's storage controllers? I also found some later versions at Danny's ftp, ftp://ftp.cs.huji.ac.il/users/danny/freebsd/ But im not sure it will be any more features or if it will work with a 7.3 src? ( ftp://ftp.cs.huji.ac.il/users/danny/freebsd/iscsi-2.3.1.tar.gz ) I hope you guys on the list can help. With Regards /Anders Larsson
