Now I put also that and it seems to work, thanks for pointing it So at the end I have the multipath.conf default file installed by vdsm (so without the # PRIVATE line) and this in /etc/multipath/conf.d/eql.conf devices { device { vendor "EQLOGIC" product "100E-00" path_selector "round-robin 0" path_grouping_policy multibus path_checker tur rr_min_io_rq 10 rr_weight priorities failback immediate features "0" no_path_retry 16 } } Recreated initrd and rebooted the host and activated it without further problems. And "multipathd show config" confirms it. But still I see this # multipath -l 36090a0c8d04f21111fc4251c7c08d0a3 dm-13 EQLOGIC,100E-00 size=2.4T features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 16:0:0:0 sdc 8:32 active undef running `- 18:0:0:0 sde 8:64 active undef running 36090a0d88034667163b315f8c906b0ac dm-12 EQLOGIC,100E-00 size=2.0T features='1 queue_if_no_path' hwhandler='1 alua' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 15:0:0:0 sdb 8:16 active undef running `- 17:0:0:0 sdd 8:48 active undef running that lets me think I'm not using the no_path_retry setting, but queue_if_no_path... I could be wrong anyway.. How to verify for sure (without dropping the paths, at least at the moment) from the config? Any option with multipath and/or dmsetup commands? Gianluca
