Description of problem: When you boot some systems with multipath devices, the devices are not correctly created. This is because when multipath is run during the boot process, the devices are not completely initialized yet. How reproducible: Easy if you have the right hardware. It seems to happen most commonly with EMC storage Steps to Reproduce: 1. configure multipath on a system. 2. reboot 3. Actual results: not all multipath devices are created. Expected results: all multipath devices should be created. Additional info:
To fix this, you simply need to make multipath check if the device is not initialized yet, and wait for it if it's not, like multipath does in RHEL5
