asked on

hyper-v virtual server

i have a 3 virtual servers using microsoft hyper-v
each server has 3 vhd;s a C:\ , D:\ and a E:\ drive
the D and Edrives are raid groups on a DAS device

the DAS device is attached to the host server via a sas card

I need to expand the driives from 150gb to 300gb each
i just purchased a second DAS with larger hard drives
my plan is to move D and E to this new DAS

this is where i need advice, once i configure the new DAS and create 2 new raid groups how do i move the D and E drives off the virtual server to this new DAS device

this is a SQL database server and these drives are used for the sql data files, also will need to keep downtime to a minimum as this is a pruduction environment and my maitenance window is small to say the least

also whats the safest and easiest way to move a VM to a new host?
You are not moving to a new host, you are only moving the file. Shut down the VM, go to the hard drives section, and where it shows where your VHD is stored, click on edit to expand the VHD file, or browse to pick the new location for the file. Obviously you need to copy it to the new location first.

kevinhsieh, i also want to phyisically move the VM to a new host (a more powerfull server)
There is an export/import function that I have never figured out. What I always do is shut down the VM and copy over the VHD files to the new host, and then create a new VM with whatever settings are appropriate for CPU, RAM, network, etc. This requires you to reconfigure the network interface if you're using a static IP, but you can't get into any trouble this way because you can always just start the VM on the old host.

Once the VM is running on the new host, you can delete the VM from the old host and delete the VHD files.
