Red Hat Bugzilla – Bug 436201
Multipath doesn't wait for devices to be initialized on boot
Last modified: 2010-01-11 21:31:42 EST
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.
Easy if you have the right hardware. It seems to happen most commonly with EMC
Steps to Reproduce:
1. configure multipath on a system.
not all multipath devices are created.
all multipath devices should be created.
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
