Modifying volume settings housing Virtualized Servers

I need to expand a volume to accommodate an additional virtualized server. This volume houses the virtual machines for two other virtual servers. The machines currently stored on the volume are Server 2003 and 2008. Expanding the volume seems very simple until I read the help text and ran across this message, "Warning: Not all operating systems, file systems, and applications easily handle volume size changes or behave in a predictable manner when you change a volume size." Are there any considerations I need to consider when expanding the volume size of my Equallogic that houses my virtual machines? Thanks.

    ESX, Xen or Hyper-V?

    I don't think there will be a problem expanding the volume within the limitations of the filesystem/OS. If you're working with a basic NTFS volume, you shouldn't have any problem growing up to 2TB. If you need it bigger than that you'll need to stand up a GPT disk and move to it (it has to be empty in order to convert from basic to GPT). You should probably shut your apps/servers down that use this LUN and take a snapshot before making the change just to be safe.

    Thanks for the help, but now I have a new issue. I tried to bring another volume online on a Server 2008 datacenter, but I can't bring the volume online. It says the disk is offline due to a policy set by the administrator. Our 3 servers went down because of SP1 and the new volume is a snapshot. Thanks in advance.

    Obviously, you will want to take offline any LUNs that you really don't want to have online.
