Hello,

For anyone interested this is how I solved the problem.

First, please note that as I mentioned earlier the OVirt documentation states that ALL the iscsi sessions/paths must be configured when adding the storage domain:

http://www.ovirt.org/documentation/admin-guide/chap-Storage/

Adding iSCSI Storage

...

Important: If more than one path access is required, ensure to discover and log in to the target through all the required paths. Modifying a storage domain to add additional paths is currently not supported.

So one way to fix this issue is:

1. Put the Storage domain under maintenance

2. Remove the storage domain from the datacenter (do not wipe/format)

3. Import storage domain using all the iscsi paths

Another way that I think is better because it does not involve deleting the storage domain is to use the REST API and/or OVirt Shell.

The storage domain must be in maintenance and the iscsi storage connection must exist. The upside is that the storage domain does not have to be deleted and imported which may not be easy if there are VMs using that storage domain.

First we need to have the storage domain ID and the storage connection ID (this one I got using the first method on an empty LUN)

[oVirt shell (connected)]# list storagedomains

id : d591d9f0-.....

name : ISO_DOMAIN

description: ISO_DOMAIN

id : 7d30dff2-.....

name : LUN

description: ISCSI LUN

[oVirt shell (connected)]# list storageconnections

id : b793b463-.....

id : 65300f39-....

[oVirt shell (connected)]# show storageconnection 65300f39-ac93-423a-9692-15984f842ae2

id : 65300f39-.....

address : ip.addr.x.x

port : 3260

target : iqn.1992-04....

type : iscsi

username: username

With this info make a POST request to the API using curl

#!/bin/sh -ex

# https://ovirt.addr/ovirt-engine/api/storagedomains/STORAGE-DOMAIN-ID/storageconnections

url="https://ovirt.addr/ovirt-engine/api/storagedomains/521fcfdc-...../storageconnections"

User="admin at internal"

password="*********"

curl \

--insecure \

--user "${user}:${password}" \

--request POST \

--header "Accept: application/xml" --header "Content-Type: application/xml" \

--data '

<storage_connection id="430ee71d-......">

</storage_connection>

' \

"${url}"

If there are easier/simpler ways please let me know =)
