Hi, <br><br>I am seeing this error with multipath-tools device-mapper-multipath-0.4.9-23.0.9.el5 and 2.6.32-200.20.1.el5uek<br><br>device-mapper: table: 253:4: <b>multipath: error attaching hardware handler</b><br>device-mapper: ioctl: <b>error adding target to table</b><br>
<br><br>multipath.conf has this. I am trying to use rdac.<br><br>devices {<br> device {<br> vendor "*"<br> product "*"<br> features "1 queue_if_no_path"<br>
hardware_handler "1 rdac"<br> path_selector "round-robin 0"<br> path_grouping_policy group_by_prio<br> failback immediate<br> rr_weight uniform<br>
no_path_retry 20<br> rr_min_io 1000<br> path_checker rdac<br> prio rdac<br> }<br>}<br><br>I have tried doing multipath -F and then restarting multipathd but the error does not go away. <br>
Is this a bug thats been fixed in later versions by any chance?<br><br>thanks in advance,<br>Harsha<br>
