Just to follow up on this, if you have a RHEL5.1 system with SELinux enabled and current versions of device-mapper-multipath tools, you might want to be aware the multipath is probably broken for you. Path failures should be detected, but it's likely that multipathd will not function properly and will fail to restore paths automatically when they recover. If you have a rolling outage (such as is common during a maitenance event) it's likely to leave your system in a case where all paths are shows as failed. Redhat is aware of this issue but has not yet released fixes publicly. The current workaround is to disable SElinux (it seems it has to be disabled, not just set to permissive) or possibly revert to older device-mapper-multipath tools (not sure if this works, but I don't think I had this problem until the recent "bugfix" versions which attempted to correct problems with root-on-multipath configurations). Hopefully Redhat will get this critical fix out the door soon.
