Hi Shani,

Yes I can add a LUN manually in the GUI.

With the verbose parameter I get some information when I run the command:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<fault>

    <detail>For correct usage, see: https://olvmmanager.continentale.loc/ovirt-engine/apidoc#services/disks/methods/add</detail>

    <reason>Request syntactically incorrect.</reason>

</fault>

* Closing connection 0

But I can’t find a syntax error.

In your last post you use the URL “https://********************/ovirt-engine/api”. Is this correct?

I think the correct URL is “https://********************/ovirt-engine/api/disks”

Best Regards,

Michael

Betreff: Re: [ovirt-users] How to create a new Direct LUN with the API

I was able to use your parameters and create the FC with the mentioned LUN. [1]

- Are you able to add it manually from the UI?

- The only difference I can think of is the headers, maybe adding the URL address, "--verbose" and "Content-Type: application/xml" [2] will show the missing info?

Hi,
I tried to create a new Fibre Channel Direct LUN with the API. But it doesn't work. My command is:

I think there are parameter missing. But I can't find a working example.
Please help.
