Windows 2008 Cluster – Extend Volume option greyed out!

After I increased the storage presented from the SAN to the host (using the SAN tools) and completed a rescan, the extend volume option greyed out.

After a little research, I found diskpart provided a quick answer to my problem. (Remember to backup your data.)

Hope this helps…
