Re: RHEL5.3 multipath EVA 8000
Try running a 'multipath -ll' and see if it shows '[ready]' instead of '[undef]'.
I have a SLES10 box here using mulitpath and it does the same thing. I'll have to dig a bit to see why it reports undef on the '-l' option, but I know my multipath is working. I've pulled all the cables while the database is running, just to prove it out.

Re: RHEL5.3 multipath EVA 8000
Can you post the exact syntax of your 'cp' command?
The last field in the path line is the dm status, which is how the kernel looks at it. The 'multipath -l' reports on the configuration from sysfs and the device mapper. The 'multipath -ll' reports from those two places plus any other components (path checkers, etc.) so it gives more information and is probably more accurate.
