Parallel Import-VApp Limitaion

[Oriel_Belzer]

Hi,

I'm trying to deploy multiple OVFs in parallels using the Import-VApp powercli.

I'm using the RunASync flag in order to make sure that the command does not wait until it finishes and returns immediately.

But even using the Async flag I'm still getting to a problem deploying more than 2 in parallel.

The first 1 that I'm deploying returns as expected, but when I'm deploying the seconds one it just hang until it finishes although I'm using the RunASync flag.

Does anyone know if there is any limit for deploying multiple OVFs in parallel ? Is it configurable ?

Thanks in advance for all helpers !

We had that question before, see Does esxi host block mulitple import-vapp with runasync

But I never found a definitive answer I'm afraid.

Yes I saw the other thread you mentioned but seems like no official answer from anyone

I hope to get some answer in here.

Thanks.

It turns out that this is an issue of the ESX server. When multiple OVFs are uploaded simultaneously ESX server stops responding. Keep in mind that it only happens with standalone ESX servers. When the ESX is managed through a VC everything works fine. The number of simultaneous uploads varies - sometimes the server stops responding after the third upload, sometimes after the tenth. The ESX server team is working to resolve this issue.

Thank you !

Finally we got the answer

The fact that it is working fine when the ESX is managed by the VC it is OK but not helpful in my case because in my case the VC is part of the VMs that I'm trying to deploy on the stand alone ESX that in a later stage will manage the same ESX that hold the VC VM .... (I hope that was clear enough 😕 ).

Maybe you have any idea when this issue should be addressed by the ESX team ?

Thanks again !

Unfortunately I don't have such information. If you have another running VC you can temporary attach the ESX to the VC, deploy all the OVFs and then detach the ESX from the VC.

Yes that is an option ... I will look into that.

Thanks again for your help ! You really helped my out here.

Thanks.
