Expand/Extend disk in SQL 2014 AAG running on VMware

Question

I created a 2-node AAG in vSphere 5.5 running Windows Server 2012 R2 and SQL 2014 and noticed when I tried to increase the data drive (non-boot volume) the newly allocated VM disk space is reflected differently between compmgmt.msc and Server Manager>Files
and Storage Services>Volumes>Disks.
I can extend the disk using compmgmt.msc without problem but Server Manager on the other hand doesn't even recognize that there's new space available to allocate.
So my question is about whether I'm expanding disk the correct way in an AAG setup by using the tried and true Computer Management interface.

Answer 1

1) Using GUI :- Computer management => 
Right click disk => extend disk=>select size => finish
2) USING CMD:-
Download the DiskPart utility from the Microsoft website, then install
it on your computer.
Go to Start, Run, then type
cmd
to start a command-line session.
Type
diskpart
to start a DiskPart session.
Type
list volume
to list the current volumes. The list will look like
Volume ### Ltr Label Fs Type Size Status Info ---------- --- ------------------- ----- -------- ------- Volume 0 C NTFS Partition 10 GB Healthy System Volume 1 D Data NTFS Partition 9 GB Healthy Pagefile
Type
select volume <volume number>
to select the volume you want to extend.
Type
extend
to extend the selected volume. If you don't pass any parameters, DiskPart will use all unpartitioned space on the current disk. Alternatively, you can type
extent size=<size in MB> disk=<disk number>
to set a size and disk to use for the extension.
Type
exit
when you're finished.
check and confirm...
