Using Compare-Object to audit group memberships for differences
As mentioned in the Listing the members of a DRS group recipe, you can easily compare a rule to the existing configuration as an auditing procedure. In this recipe, you will retrieve the list of existing VMs in the group, and then compare that with a list of the VMs from the desired group. You will use the group created in the Creating a DRS group for virtual machines recipe named TTYLinux VMs.
To make the results interesting, compare against the virtual machines WinVM1 and TTYLinux1. Only one of these should be a match, while the others should fall out as differences. Then, you can compare the existing groups against a wildcard pattern match of TTYLinux*.
Getting ready
