I think this is your problem:

2017-09-04 03:26:14,272+02 INFO
[org.ovirt.engine.core.bll.storage.domain.AddExistingBlockStorageDomainCommand]
(org.ovirt.thread.pool-6-thread-24) [2383eaa0] There are existing luns
in the system which are part of VG id
'vvIoS2-fZTZ-99Ox-Ltzq-pr8U-SL2z-wbTU8g'

I guess you can try to remove this disk/lun from the engine and let it retry.

If the only disk is of the hosted-engine, I guess it should have been
removed by '--he-remove-storage-vm' - if so, please open a bug
describing your flow in detail. Thanks.

Best,
