I've just finished going through the process of getting our SAN gear working on RHEL5 with multipathing. I've got a Sun 6140 which I think is very similar to yours. They both are from ingenia. You'll want to use a *NON* AVT host type on the SAN. I've set mine to type "Linux" and it works great. cheers, --james -----Original Message----- From: dm-devel-bounces@xxxxxxxxxx [mailto:dm-devel-bounces@xxxxxxxxxx] On Behalf Of Nuno Fernandes Sent: Monday, September 24, 2007 9:06 AM To: device-mapper development Subject: Device-mapper-multipath RDAC hello, Just a question: With recent support for rdac hardware handler in kernel 2.6.23-rc7, what configuration should be in storage DS4700? AVT (Automatic Volume transfer) turned on or off? When it's turned on, luns keep on jumping from controller to controller..
