Your blacklist definition is wrong. You provided. """ blacklist { wwid "3600605b0039afe20ff000054052e7d38" vendor "SMART" product "SMART" }
defaults { user_friendly_names yes } """ wwid cites an entire device, vendor & product cite a different device and must be included in device { } block. If you look at the "show config" output, you'll note that your blacklisted device by vendor/product isn't there. Change to: """ blacklist { wwid "3600605b0039afe20ff000054052e7d38" device { vendor "SMART" product "SMART" } } defaults { user_friendly_names yes } """ update your initrd (multipath.conf is copied there) and reboot. Also, it would be nice to see a list of all your storage devices. I prefer lsscsi, e.g. root@nashira:~# lsscsi [0:0:0:0] cd/dvd hp DVD A DS8A5LH 1HE3 /dev/sr0 [2:0:0:0] disk NETAPP LUN 8020 /dev/sdb [2:0:1:0] disk NETAPP LUN 8020 /dev/sdd [3:0:0:0] storage HP P410i 3.66 - [3:0:0:1] disk HP LOGICAL VOLUME 3.66 /dev/sda [5:0:0:0] disk NETAPP LUN 8020 /dev/sdc [5:0:1:0] disk NETAPP LUN 8020 /dev/sde Finally, since this is FC, how is it zoned? Detailed port level topology please.
