SCSI Drives question

["Bret Stern" <bret_stern machinemanagement com>]

On my server, i have two 18gb scsi drives which are
part of a Logical Volume (LVM), and are internal
drives to the Dell 2450.

They are /dev/sda, and /dev/sdb


I'm adding a Dell Powervault connected to an Adaptec
scsi card (not the onboard scsi) and the two 18gb drives
above now become /dev/sdh and /dev/sdi.

It seems like the server drives should stay /dev/sda and /dev/sdb,
and the new drives in the powervault should start their
scsi id's after after those in the server??

I need some scsi tips.
