Boot into the iSCSI non-offload/L2 boot from SAN operating system. Issue
the following commands to install the Open-iSCSI and iscsiuio RPMs:
#
rpm -ivh qlgc-open-iscsi-2.0_873.111.sles12p2-3.x86_64.rpm --force

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"
.
