I have a server running RHEL5 (HP Proliant DL365) connected to a EVA. LVM is used for the SAN disks like this

/dev/sdav VolGroup09 lvm2 a- 150.00G 90.00G /dev/sdbi VolGroup08 lvm2 a- 150.00G 0

I want to setup Proliant support Pack and configure the Device Mapper Multipath Enablement Kit from HP.

How do i get LVM to use the /dev/mapper/* disks instead on /dev/sd* disks?

Install RHEL with "linux mpath" option. Otherwise, you can follow the following: http://thomasvogt.wordpress.com/2007/11/29/linux-san-multipathing/

Start with one disk at a time.

It will be easier to reinstall the OS.
