hi,
i'm using three different generations of hardware for my oVirt
hypervisor hosts. they are not exactly the "same", but very
"similar".
- all were installed with oVirt Node 4.1.x installers
- all have (2-4) local SSD disks for oVirt Node OS
- all were configured with manual partitioning and SW RAID 1 with
two SSD disks for oVirt Node OS
after initializing the third generation of hosts (with 4 SSD disks)
i noticed the difference in multipath configuration for the local
disks.
I may be wrong but it rarely matters on local disks. Unless they have
some kind of active-active (multi-channel?) controllers.

thanks, you're probably right. i was asking
(a) for the sake of consistency
(b) out of curiosity
(c) because the multipathing adds an additional level of abstraction in
the whole setup (which includes SW RAID)
strictly speaking none of these are show-stoppers , i'll manage...
