P2000 G3 SAS VDISK EXPANSION

Hi,
I have a question about the expansion of a vdisk on a storage p2000 g3 sas.
My system consists of 3 bl460c g7 connected to a p2000g3 sas.
The operating system is vmware esx 5.1.
The vdisk to expand is presented as a virtual rdm to my Exchange 2013 virtual machine.

Now I have finished the free space and I have to expand the vdisk. 

 

Reading the document Technical HP P2000 G3 MSA white paper Best Practices on page 14 it says:

 

Virtual Disk Expansion Best Practices


With the ever changing storage needs seen in the world today, there comes a time a when storage space gets exhausted quickly. The P2000 G3 MSA Gives You the option to grow the size of a LUN to keep up with your dynamic storage needs.
A Virtual Disk (Vdisk) expansion Allows you to grow the size of a Vdisk in order to expand an existing volume or create volumes from the newly available space on the Vdisk. Depending on several factors, Vdisk expansion can take a significant amount of time to complete. For faster alternatives, see the "Vdisk Expansion Recommendations" section on page 15.

 

So my question is:

 

the vdisk can be expanded online with my vm on? Correct?

 

or

 

the expansion of the vdisk must be done offline?

 

Thank You

 

Greetings
