SCVMM- Part7 (PowerShell)

  • 项目

As you should be aware SCVMM like Exchange 2007 is based on PowerShell (previously known as "Monad").  This enables you to perform every action that the GUI does from the command line and in some cases more.  PowerShell is a pre-requisite for SCVMM and is installed during the setup.

You can start PowerShell from a command prompt by typing:- "PowerShell", or there is a shortcut on the SCVMM Server menu - START-Microsoft SCVMM-Windows PowerShell - VMM 

I'd suggest you use the latter as the SCVMM specific cmdlets (not sure of the precise term here) are loaded and available.

If you need a primer on PowerShell:

Visit the Windows PowerShell Team blog at:    https://blogs.msdn.com/PowerShell or

GET_VM

The Get-VM command returns information about the SCVMM server and the Virtual Server hosts and guests, the syntax at is most simple would be:

get-vm

This will prompt you to enter the name of the SCVMM server, so it could be easier just to enter

get-vm -server <server name>

Where <server name> is your SCVMM host, this will return the following data (I've only shown one VM to save space, and replaced some data with "xxxx", all VM's will be listed by this command).  Remember all syntax examples I give you need to be entered on a single line. The information returned is:

So this list might give you all the infomation you would need, but you might want to filter the data, this example does just that, you may wish to look up what the "Format-List" command does in the primer links I mentioned above:

get-vm -server hotnas | format-list vmstate

VMState : Stored
VMState : PowerOff
VMState : PowerOff
VMState : PowerOff
VMState : Running
VMState : Unsupported

However the Vmstate information on it's own isn't that useful so we need to build up the query, for example:

get-vm -server hotnas | format-list hostname,name,vmstate

HostName : hotnas.xxxx.xxxx.xxxx.com
Name : Clwatson-lhs1
VMState : Stored

HostName : hotgold.xxxx.xxxx.xxxx.com
Name : eiger
VMState : PowerOff

HostName : hotgold.xxxx.xxxx.xxxx.com
Name : LHS2
VMState : PowerOff

HostName : hotgold.xxxx.xxxx.xxxx.com
Name : infmom
VMState : PowerOff

You can of course return any data that you wish to filter by changing my example queries to include the fields you are interested in, the output of the command get-vm -server <server name>in the left column, gives you the available options, these are the current ones (as of Beta 1):

More useful SCVMM Powershell commands will follow...

 

UPDATE:
For beta1 there is no PowerShell documentation nor is the the powershell interface directly supported. 
We'll support the powershell interface in beta 2 and the final release of
SCVMM
