Dear all,

since several days i try to install the hosted engine initially to an iscsi multipath device without success.

Some information on the environment:

- Ovirt Version 4.3.3

- using two 10gbe interfaces as single lacp - bond for the ovirtmgmt interface 

- using two 10gbe storage interfaces on each hypervisor for iscsi storage

-- each storage interface is configured without any lacp bonding or 802.1q tagging, etc (on the switches the vlan is configured; port based vlan)

-- each storage interface lives in a serarate vlan were also the iscsi target is available, the iscsi target has 4x10ge interfaces

-- so; each storage interface is connected to a iscsi target through a different vlan

The documentation here is for me unclear:

>Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options.

This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ?

I login to the two iscsi targets and get in sum 8 pathes, 4 from each interface and iscsi target.

I have then the mpath device on the hypervisor available and i can  mount the mpath device and put (test) data on it.

In the cockpit interface the mount can also be activated and is recognized correctly.

multipathd -ll and lsblk looks good. Everything seems to be fine.

But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data.

So, basically i just want to define my mpath device - when entering the data for one of my iscsi target I can see the 4 pathes of the single target,

and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have 

here for using the multipath device.

I' m lost - what is the usual way to install the HE on a mutlipath device ?

Do I have to change the configuration of the storage interfaces or the iscsi network design?

- Are bond interfaces for these iscsi connections mandatory ?

Did I missed something obvious ?

Can I put in my multipath data into the answerfile somehow to get rid of the last step of the assistant ?

Is it not possible in general ?? :

Sorry in advance for the long mail .... 1!^^

br,
