• Configuring Network Adapter TCP/IP Settings using Powershell 4.0 Cmdlets .

  PowerShell 4.0 is a requirement for these cmdlets to work.The GUI( Graphic User Interface) is commonly used to configure network adapter settings or the good old netsh command. But if I had to work with Hyper-v core or Windows Server 2012 R2 core, there’s a number of PowerShell cmdlets that could be used in place…

  I’ve been running Windows Server 2012 Failover Cluster for about a year and it’s been stable up until now. Recently, I encountered an issue where Live migration of VMs failed across all hosts in the cluster.

• Checking Available Disk Space and Memory with Powershell.

  I frequently need to display the disk size, available disk space properties and Processor details of my remote Hyper-v 2012 Hosts servers. I could use the Computer Management snapin to do this, but it involves too many steps just to get there. The Get-VM cmdlet while cool, will not display disk based properties. So I…

• Configuring multiple ISCSI Connections for Multipath IO using PowerShell.

  This post will be focused mainly on the ISCSI Initiator host and configuring multipath IO paths to an ISCSI Target. The ISCSI Target portal has already been configured with 2 network paths for ISCSI. The ISCSI Service by default is in a ‘Stopped’ state. So, we’ll begin by starting the service: [hyperv00]: PS C:\Users\admin\Documents> Start-Service…

• Configuring Hyper-v Host Network Adapters for ISCSI Storage Connectivity with Powershell .

  Windows Server 2012 R2 with PowerShell 4.0 has hugely expanded support for configuring multiple NICs on a Cluster/ISCSI Initiator node via command line. After deploying multiple Network Interface Cards on my Hyper-v host, it took me a while to figure out how to properly configure the NICS with PowerShell . Prior to Windows Server 2012,…
