multipath device error "ioctl: error adding target to table" on Red Hat Enterprise Linux

Solution Unverified - Updated -


  • After wiping the multipath bindings file (through 'multipath -F' as well as removing the bindings file), and rebooting,  the server returned with the LUNs in place, and mounted the file systems without issue; however LVM had them completely cross-mapped and corrupted.


  • Red Hat Enterprise Linux 5 (RHEL5)
    • This problem has been observed on RHEL5.7.
  • Boot from SAN system

    • Devices are multipath'd using device-mapper-multipath-0.4.7-46.el5_7.1.
  • LVM2 boot disks, as well as non-boot volume groups using lvm2-2.02.84-6.el5_7.1

    • One of the devices making up a volume group is not a multipath device:
