multiple MoRef ´s for one VM

Marcel00M · ‎03-11-2011

Hello,

while trying a function from the powercli sub forum I figured out, that I have VM´s with multiple entrys (an example is listed below).

I have only problems when I want to use the function. I believe because of this multilple entrys.

Everethinks else works well. But imho this can not be good and should be fixed.

After deregistering such an VM, there still was an entry. But only one. The wrong one, I think thats the needless one, which should be removed.

Afte registering the VM again, there where two entrys again.

I think, we have some "corpses" in our VC DB?

Can some one tell me:

How can they occur?

How whe can remove them?

Is it dangerous to remove them?

How whe can find the" right" entry for a VM, without unregistering it?

Thank You very much!

Example

Example is QDEAHX with MoRef : VirtualMachine-vm-498 and VirtualMachine-vm-14888

After an unregistering only the VirtualMachine-vm-14903 left. I think, thats the needless one.
