Not for the same task, but in some way related and useful in case of dm-multipath support..: http://kbase.redhat.com/faq/docs/DOC-2882 Note that you can also set no_path_retry per device, having different configs for sbd device and the other ones. Instead, the "polling_interval" is global and actually means: The interval between checking all possible paths for all multipath paths of a LUN So assuming 4 paths to LUN A: check path1 check path2 check path3 check path4 polling_interval check path1 check path2 check path3 check path4 Gianluca
