I need
access to both environments since I`ll deal a lot with both of them in
different scenarios, like proof of concept, demos and researching. Sounds fun? –
it is!
Below is
a very simple overview of my environment, showing you that I have 2 clusters in
a single domain. 1 Windows Server “8” Hyper-V cluster and 1 Windows Server 2008
R2 Sp1 Hyper-V Cluster with the current SC 2012 components installed and
orchestrating the magic.
To run a
SAN, I`ll use Windows Server “8” with the inbuilt iSCSI target, and i`m looking
forward to test and play with Storage Pools and Storage Spaces.
So what
have I done to this point, with no SAN for my VMs? People who know me also know
that I`m addicted to clusters. I need them in my life. But the life has treated
me good because I`ve been running Windows Server “8” directly on my laptop.
There
are several reasons for this. Here`s a couple of them.
1.
Kristian,
you better start learning Powershell. No discussion. Do it.
2.
Do
all the possible research related to Hyper-V, and especially by using
Powershell.
3.
Remember
to learn well, since this will be your bread and butter.
So,
let`s talk a bit about Powershell in this blog post.
Several
top dogs at Microsoft have stressed that it is extremely important for the
technologist to be able to manage things through Powershell. And if you see
this in the cloud context where as much as possible should be considered for
automation, powershell is the key since the robust API towards SC 2012 and
Windows Server “8” would be …. Powershell!
So
here`s some handy Powershell cmdlets that I have been using the last days.
(Note,
this is not rocket science but it`s very handy)
Start all your VMs
Get-VM *
| start-VM
Shut down all your VMs
Get-VM *
| stop-VM
Move storage
Move-VMStorage
“VM name” “Destination” (Example:
Move-VMStorage “SCOM2012” “E:\VHDs\SCOM2012”
Enable Dyanmic Memory on every VM
Get-VM *
| set-VMMemory –Dynamicmemoryenabled $true –startupbytes 512MB –minimumbytes 100MB
–maximumbytes 6GB
(Thanks to Aidan Finn)
Clean up your environment after some heavy Storage Migration demos
Get-VM |
% { Move-VMStorage $_.Name “E:\VMs\$($_.Name)” }
(Thanks to Benjamin Armstrong)
And of
course, there`s a lot of new cmdlets related to the Hyper-V Role.
To get
an overview, type:
Get-commands
–module Hyper-V
This
will list all the cmdlets for you. You can also play around and use Powershell
ISE tool to help you to build, test, and evaluate scripts that you create by
using Powershell.
Oh, I
have created some scripts as well, but I`ll save them for later in another blog
post.
So my
next step would be to move all my VMs with SC 2012 installed from my laptop
over to the newly created lab. I will show the examples of how this was done in
another blog post later.
Cheers,
