This is what is happening as soon as the system comes up. There are no multipathing devices created. Once I run the multipath command only then the /dev/mpath/mpath# devices get created. It looks like I am missing some thing when the system boots up. The system has the multipathd start up script in /etc/rc3.d. Any suggestions?
