Simplest thing to check is if your host can discover and write to the LUN. Is
it possible that more than 1 node has the same client IQN ?

Hi everyone.
I need help understanding a failure deploying the hosted engine on a
fresh-installed oVirt 4.5.4 el8 node.
After the setup via official ISO, I login via ssh in the node and I
issue the command:
# hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true
-- Note --
The extra ansible variable is the only way I found to inhibit the
deployed hosted engine downloading last OS updates that will break
Python compatibility between the ansible playbook in the node deploying
and the ansible host in the engine deployed.
Without that extra variable the deployment fails with fancy reasons.
-- End note --
The deployment goes, until i specify an iSCSI target and a (free) LUN.
The playbook adds the storage domain, creates the HE disk and transfert
the HE vm to the domain. Then an error occurs:

Then the playbook cleans all the installation and exits.
Really cant' figure what's going on ...
This is the best point i reached in deploying HE after two weeks of
failures and errors of any kind.
Please, can someone point me in the right direction to solve this new issue?
Thanks.
