Description of problem:

There is a need to test and document a recommended way how to make an existing RHV environment to utilize iSCSI bond feature (using the same subnet). We have a quite spare (in the matter of scenarios) description of iSCSI Bond in the "Administration Gude"

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/administration_guide/sect-preparing_and_adding_block_storage#Configuring_iSCSI_Multipathing

However, most customers start their settings from a simple setting and then they want to migrate to iSCSI bond.

This doc BZ was created from https://bugzilla.redhat.com/show_bug.cgi?id=1565198
Before we publish the recommended way, we have to test using continuous IO. 

Version-Release number of selected component (if applicable):

RHV 4.x

How reproducible:

Let's take into consideration the worst case, e.g customer has a bond (from 2 NICs), on top of it Logical Network (responsible for a storage connection). Now he wants to move it (without downtime) to iSCSI bond using the same subnet. I have tested such scenario, it is working properly: I broke the bond, prepared Logical Networks (not-required), attached to NICs, created iSCSI Bond, everything on a running hypervisor. It seems to be ok, but I afraid to give recommendations for production environments.

Actual results:
It is working properly

Expected results:
We need to have a confirmation that VMs running on a host are not affected and nothing wrong with their I/O operations.
