Root is on a multipathed device, multipathd can not be stopped

Hi guys.

I am installing RH 5.8 booting from a HP SAS storage with multipath.. the server is a HP proliant..

there is a / partition, swap and /var all in the storage..

root is on a multipathed device multipathd can not be stopped

I can restart the server and it will boot.. but I am not sure if this is a critical issue that could affect me in the future.. the server will be in production and the only reason for restart or shutdown will be a for a very critical failure...

I am trying to find information about this but I allways end in any page showing  the script which stop this service.. not sure if it is a bug or should I replace the original script with the one I found..

the other thing is if I update the system with yum update it wont boot with the new kernel.. I think I should rebuild the kernel image with mkinitrd.

If I run the command multipath -v0 or 1 2 it doesnt show anything..

any idea?

thanks in advance
