sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi Jorick, This error is most often caused by multipath attempting to map a device which is already in use, such as if multipath error getting device linux its mounted or mapped by an active LVM logical volume. If the blacklist
Device-mapper Ioctl Error Adding Target To Table Multipath
in /etc/multipath.conf does not restrict multipath from mapping the device, then when it gets run during boot it will attempt
Device-mapper Ioctl Error Adding Target To Table Redhat
to map it. Because the device is in use, this mapping will fail. Have you tried the blacklisting procedure mentioned at comment 3 in the bug? https://bugzilla.redhat.com/show_bug.cgi?id=675366#c3 ----- Original Message ----- > From: https://access.redhat.com/discussions/1307143 "Jorick Astrego"

lun after system reboot Issue is multipath service is running but the server was not login in to the iscsi storage.,So we manually login to the storage server using iscsiadm command then we are able to discover the device and mount.
