The following two sections of code can be ran independently or used in conjunction with Alan Renouf’s vCheck script. They return network specific issues that could happen in a vSphere environment. <\/p>\n
The first check makes use of a $clusters variable, which can be created using the following line of code:<\/p>\n
\r\n$Clusters = Get-Cluster\r\n<\/pre>\nThe following section will report on any port groups that do not exist on all hosts in a cluster. This is a fairly common issue with standard vSwitches, but is typically resolved by using Distributed vSwitches (for the Enterprise Plus users).<\/p>\n

This could be a new network that simply doesn’t have VMs yet, or an old network that is no longer required.<\/p>\n
