How to avoid creating sd* disks when working with multipath?

Question

linux

When connecting a disk through, for example, a fiber channel using several connections, a lot of sd * disks are created, which then, when using multipath, you can use one mpathX, which understands that this is one disk and work with it already. Tell me how to set it up so that sd * are not created, but only mpathX,

Answer 1

mpathX- this is a virtual device, there must be some real block devices under it. You do not require that for a software raid you only mdXhave , without real partitions / disks inside?

Answer 2

sd* are just real disks that are multipassed into one. Real SCSI disks don't interfere with your work - you just don't need to use them.
