NOTE
If you are using an HPE Synergy chassis managed by HPE OneView, create
a server profile and set the
Function Type = "Ethernet"
. HPE OneView
creates a virtual MAC. When performing the migration steps, you may need
to reapply the HPE OneView profile with
Function Type = "iSCSI"
and
apply the profile as
"User Defined"
.
