There is a bug in some version of RHEL where multipath has "mpath_prio_hds_modular" instead of "/sbin/mpath_prio_hds_modular". Update your multipath tools package or fix it in your /etc/multipath.conf (this requires some careful modifications!) --Malahal. PS: since execv looks for your executable file in the 'cwd', you can probably make it work by just copying /sbin/mpath_prio_hds_modular to /mpath_prio_hds_modular (I am assuming that multipathd daemon makes "/" as it ***home*** before calling this.)
