I've tried "manual" as well - no difference :-( By the way, I had trouble getting multipath to use the rdac hardware handler. My solution became to add the following in a new "/etc/sysconfig/ modules/dm-rdac.modules" file: #!/bin/sh modprobe dm_rdac >/dev/null 2>&1 Before that, hwhandler stayed at value 0 no matter what I put in /etc/ multipath.conf. Unfortunately, this didn't seem to make a difference, either. But it sure seems more logical. My options for testing different configurations have been closed for now, so for the time being, I'll have to accept that changes to "preferred path" aren't accepted by the server. Everything else works fine: The setup passed all pull-and-push-fiber-cable tests that I could think of. When a new opportunity for testing comes up, I suspect that I may have to work with the QLogic driver and perhaps firmware level/settings on the DS4800. -- Regards, Troels Arvin <[EMAIL PROTECTED]> http://troels.arvin.dk/ _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
