Scripts
Create a virtual machine
# This script will read a comma-separated values (CSV) file to create VMs.
# The CSV file is specified in $CSVPath. A log file is created by this script.
# This log file is specified in $LogPath.
#
# The script expects to see a CSV file with a header row that specifies the
# column names (variables).
# Each row after that will define a new VM to create. The variables are as
# follows:
#
# VM_NAME: The name of the new VM to create
# VM_Path: Where to create the VM's files
# Disk_Type: Differencing, Fixed, or Dynamic (the default). No value = Dynamic.
# DiffParent: Used when Disk_Type = Dynamic. Specifies the parent for the
# differencing disk
# Disk_Size: Used if Disk_Type = Fixed or Dynamic (or blank). Size in GB for the
# new VHDX
# ProcessorCount: How many vCPUs the VM will have
# StartupRAM: Amount in MB that the VM will boot up with (Dynamic Memory or not)
# DynamicMemory: Yes or No (default). Do you enable DM or not?
# MinRAM: Amount in MB for Minimum RAM if DM is enabled.
# MaxRAM: Amount in MB for Maximum RAM if DM is enabled.
# MemPriority: 0-100 value if for Memory Weight DM is enabled
# MemBuffer: 5-2000 value for Memory Buffer is DM is enabled
# StaticMAC: Any non-Null value will be used as a MAC address. No error
# detection.
# AddToCluster: The new VM will be added to the specified cluster if not blank.
# Start: If set to Yes, then the VM will be started up.

Commands
Failover Cluster PowerShell commands
This first line adds the failover cluster role to the host HV-Node01.
Add-WindowsFeature Failover-Clustering –IncludeManagementTools –ComputerName HV-Node01
To create a cluster without any configured storage:
New-Cluster –Name Cluster1 –Node Blade1, Blade2, Blade3, Blade4, Blade5, Blade6, Blade7 –StaticAddress 10.0.0.20 -NoStorage
To install management tools use the parameter -IncludeManagementTools:
Add-WindowsFeature RSAT-Clustering –IncludeAllSubFeature To run the cluster validation process:
Test-Cluster –Node Host1, Host2, Host3 To add a disk to a cluster:
Add-ClusterDisk "Cluster Disk 1"
42
To get a list of available disks:
Get-ClusterAvailableDisks | fl Name Verify Cluster Shared Volumes:
Get-CLusterSharedVolume "Cluster Disk Name" | fl Live Migration PowerShell commands
To initiate Live Storage Migration by using PowerShell:
Move-VMStorage -VMName Exch-VM1 -DestinationStoragePath "\\Server Name\VM-Store\
'
Exch-VM1"
To setup Shared Storage:
MD '<LOCAL_DRIVE_PATH>\VM-Store'
New-SmbShare -Name VM-Store -Path "<LOCAL_DRIVE_PATH>\VM-Store"' -FullAccess domain\administrator, \host1$, domain\host2$, domain\host3$(Get-SmbShare -Name VM-Store).PresetPathAcl | Set-Acl.
