I have no Problem with the failover also with SLES 9 2.6.5-7.244-smp. But i'm not working with the isci initiator. My Config: defaults { multipath_tool "/sbin/multipath -v0" udev_dir /dev polling_interval 5 default_selector "round-robin 0" default_getuid_callout "/sbin/scsi_id -g -u -s /block/%n" default_prio_callout "/bin/true" failback immediate } There are newer Multipath tools available: Im working with: multipath-tools-0.4.5-0.20 (Device Mapper is same) I recommend to update them first. :) This one is talking about the same Problem you have. http://www.querzone.de/wiki/Wiki.jsp?page=EMCClariion I don't know if this error is clariion specific.
