 a LUN disk is not in any storage domain?

AFAIK LUN disk simply resides on a LUN, that's why it has the field:
private LUNs lun;

A SD can possibly also reside on this LUN if this behaviour is desirable
(I'm not sure if this is acceptable or not in oVirt), but is not
necessary for the disk to function.

Alright, that makes sense. Thanks!

[Engine-devel] Getting the storage domain of a LunDisk

2012-08-07 Thread Hopper, Ricky 
Hi all,

Does anyone know the best way to get the storage domain of a LunDisk object? I 
don't know if there's some query or anything I'm failing to find, but I can't 
find anything within the class itself that's definitive.

Thanks,

Hi Ricky,

As far as I can see, the DiskImage class can give this--but AFAIK there is 
no way to convert a LunDisk to a DiskImage.


I am curious if the storage domain info should be moved into the Disk class, 
which is a superclass of both LunDisk and DiskImage, or if perhaps there is 
a better place for it?  Here's a partial class hierarchy that I mapped out 
when looking into this for a bug I'm working on:


BaseDisk
'- Disk
   |- LunDisk
   '- DiskImageBase
  '- DiskImage

Thanks,
Greg
