Create Datastore option in esx 6.0

Hi,

I have doubt how to specify the datastore size in creating a datastore using vsphere sdk .NET.

The New-Datastore cmdlet takes by default all the available space.

If you want to specify a specific size, you will have to use the CreateVmfsDatastore method.

Can I remove this thread ?

It's a duplicate of the one I moved to the Developer community

Yes I am not able to specify the size in createvmfsdatastore method. It is directly taking the size of available vmfs device.

Yes please move to developer community it wil be helpfull. Shall i send the code snippet which we are using?

Thanks,

Sainath

This is code snippet we are using to createmvfsdatastore.
