Regarding Linux Multipathing

Hi experts,

I have allocated LUNs to linux host ( Rhel 4.8 ) from Netapp.l have installed multipathing. I am able to see the device. I just want to know while creating VGs , we should specify /dev/sd* or mpath devices. If mpath then, whether /dev/mapper/mpath* or /dev/mpath/mpath*. If yes, then i think following steps are right, correct me if am wrong :-
1. pvcreate /dev/mapper/mpath1 or /dev/mpath/mpath1
2. vgcreate vg01 /dev/mapper/mpath1
3. creating logical volumes.

I am confused in /dev/mapper or /dev/mpath. Would appreciate if Experts can comment on this.

Thanks

I believe it should be the mpath and not the other.

Here is a How To for multipathing with RHEL 4 (but going to an EMC SAN instead)
