I learnt recently that when you Storage vMotion a VM within a datastore cluster and you check the box to select which datastore you explicitly want the VM to be migrated to, it sets the SDRS automation level for the VM to disabled. Finding out which VMs have an automation level of disabled can be… Read More »
I’m a big fan of the vCheck script by the very talented Alan Renouf and community, but a couple of the plugins don’t work as well as I’d like with our environment, where we have multiple NTP and Syslog servers and these settings can differ depending on the cluster within a single vCenter. So I’ve… Read More »
This post was updated on 9th May 2017 to fix an error condition in the script. Support for Windows Server 2012 was announced starting with ESXi 5.0 Update 2, but there was a little known flaw in this support – in that without a CPU mask, a VM could blue screen at any time. The… Read More »
Before VMFS5 the block size of the datastore determined the maximum size of a hard disk that could be added to a virtual machine. In our new glorious future it now makes no difference, but VMFS datastores that have been upgraded to version 5 will retain their old block size. The following PowerCLI will show… Read More »
Creating a Cisco UCS Profile using PowerTool This post is going to walk through creating a powershell function to create a Service Profile on a Cisco UCS domain. Later posts in this series will look at how to assign it to a server, configure shared storage on a NetApp filer, and configure the zoning on… Read More »
The following code will list the VMs which have network adapters that are not VMXNET3. This is useful for knowing what you likely have to change 😉 It will output the Name of the VM, the Type of adapter and the Network (i.e. Virtual Machine Portgroup) that it is connected to. The code will examine… Read More »
I ran into a problem recently where I needed to get the size of a volume from a NetApp filer so I could create a new volume (of the same size) and initialise a snapmirror relationship to it. The problem was that sometimes the snapmirror relationship would fail to start, reporting that the destination volume… Read More »
I’ve had to deal with two UCS systems recently, ensuring that the configuration matches on them both, most of which I was happy to go through by hand. But the long list of VLANs was another story. I could see that they can be exported, but I couldn’t find an import ability. So, a quick… Read More »
vSphere 5.0 – If you need a list of Virtual Machines and the portgroups they are attached to:
|
1 |
Get-VM -Location "somewhere" | ft Name, @{Expression={$_.NetworkAdapters.NetworkName};Label="Network Name"} |
If you need to export this to a CSV:
|
1 |
Get-VM -Location "somewhere" | select-object Name, @{Expression={$_.NetworkAdapters.NetworkName};Label="Network Name"} | export-csv "vm-networks.csv" |
Getting all the network adapters for a VM is an easy task:
|
1 |
get-networkadapter -vm [vm name] |
When you remove a network adapter, vSphere will remove it’s entry in the .vmx file. In the .vmx file, the adapter configuration options are prepended by an “ethernetX” string, where X is a number between 0 and 9. Removing the adapter, removes… Read More »
