Hi-- I've played around with changing rr_min_io values in multipath.conf on SLES10 and even after a reboot, it appears the change does not take hold and the default of 1000 remains unchanged. Here is the output from multipath -v3: (beginning removed) mpath1: pgfailback = -2 (controler setting) mpath1: pgpolicy = group_by_prio (controler setting) mpath1: selector = round-robin 0 (controler setting) mpath1: features = 1 queue_if_no_path (controler setting) mpath1: hwhandler = 1 emc (controler setting) mpath1: rr_weight = 1 (controler setting) mpath1: minio = 1000 (controler setting) mpath1: no_path_retry = 60 (controler setting) mpath1: set ACT_NOTHING (map unchanged) I would tend to think that "minio" is the equivalent of rr_min_io, but cannot be sure. I am leaning towards this assumption because even after adjusting rr_min_io to an absurdly high value, I am still seeing I/Os spread across both paths in under a couple seconds. Please note that this was just a test to verify rr_min_io taking effect. Any idea on how to override the "controler setting"? FYI, I'm using a dual-port Emulex LP10000 as my HBA. I took a look at the Emulex docs and I don't see any parameters worth throwing in modprobe.conf.
