My problem is not that I get a different mpath# device each reboot, but that the LUN with the lowest LUN id (i.e. '0' for a boot LUN) is not the mpath device with the lowest enumerator, e.g. mpath0. Quite the opposite, my boot LUNs seem to end up as the last mpath device.<br />I would expect:<br />LUN id 1 (17GB) -> /dev/mpath0<br />LUN id 2 (34GB) -> /dev/mpath1<br />LUN id 13 (500GB) -> /dev/mpath2<br />LUN id 64 (1700GB) -> /dev/mpath3Dreamshttps://www.blogger.com/profile/05824087496822119504noreply@blogger.comtag:blogger.com,1999:blog-5961248257439764692.post-48456796550967033702010-05-28T16:41:36.170+02:002010-05-28T16:41:36.170+02:00To make the /dev/mpath/ the same across all your m...To make the /dev/mpath/ the same across all your machines you can disable the 'user_friendly_names' option.<br /><br />1).

Kick multipathd to re-read: multipathd -k'reconfigure'.<br /><br />And it ought to recreate the /dev/mapper/.
