Sure enough, once we added the data storage the hosted-storage imported and 
attached successfully.  Both our hosted-storage and our VM data storage are 
from the same iSCSI target(s), but separate LUNs.

Many thanks!

Did you already add your first storage domain for regular VMs?
If also that one is on iSCSI, it should be connected trough a different
iSCSI portal.

It didn't seem to for us.  I don't see it in the Storage tab (maybe I 
shouldn't?).  I can install a new host from the engine web ui, but I don't see 
any hosted-engine options.  If I put the new host in maintenance and reinstall, 
I can select DEPLOY under "Choose hosted engine deployment action."  However, 
the web UI than complains that:
Cannot edit Host.  You are using an unmanaged hosted engine VM.  P{ease upgrade 
the cluster level to 3.6 and wait for the hosted engine storage domain to be 
properly imported.

This is on a new 4.1 cluster with the hosted-engine created using hosted-engine 
--deploy on the first host.

Glad to hear, thanks!

The engine should import it by itself once you add your first storage
domain for regular VMs.
No manual import actions are required.

No, a separate network for the storage is even recommended.

[ovirt-users] hosted-engine with iscsi storage domain

[Devin A. Bougie]

We have a hosted-engine running on 4.1 with an iSCSI hosted_storage domain, and 
are able to import the domain.  However, we cannot attache the domain to the 
data center.

Just to make sure I'm not missing something basic, does the engine VM need to 
be able to connect to the iSCSI target itself?  In other words, does the iSCSI 
traffic need to go over the ovirtmgmt bridged network?  Currently we have the 
iSCSI SAN on a separate subnet from ovirtmgmt, so the hosted-engine VM can't 
directly see the iSCSI storage.

Thanks,
Devin
