I've found this on RHV manual, which should apply to oVirt:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza=
tion/3.5/html/Administration_Guide/sect-Preparing_and_Adding_Block_Storage.=
html#Configuring_iSCSI_Multipathing
Let me know if works, because I'm considering a migration to oVirt and I wi=
ll have the same issue.

hi,

our storage admin shared the same LUN for me on two targets, which are loca=

do so). on the oVirt hypervisor side there is only one bonded interface fo=

works on the bond interface.
now i create the storage domain logging in to one of the targets connecting=
through its logical network. when i try to create a "second" storage domai=
n for the same LUN logging in to the second target, oVirt tells me "LUN is =
already in use". i understand this, but now i can't configure an oVirt
"iSC=
SI Bond" in any way.
how is this supposed to work?
right now the only working setup i can think of would be an iSCSI target th=
at uses a redundant bond interface (with only one IP addresss) to which my =
hypervisors connect through different routed networks (using either dedicat=
ed network cards or vlan interfaces). is that correct?
i feel like i'm missing something, but i couldn't find any examples for rea=
l world IP setups for iSCSI multipathing.
thanks for explaining
