PowerCLI Script to create new vDS Portgroups
We deployed new hosts into one of our office locations. Because these hosts would have different number of uplinks as well as use a LAG group instead of normal dvUplinks, we decided to create a new vDS Switch. Then, we needed to re-create all the portgroups as well. I figured, instead of manually adding 15-20 portgroups, I’ll automate it. I used this blog post as reference to do some of the work, and added the LAG and uplink changes.
When you create a new portgroup, it automatically includes the dvUplinks, but in this case, we wanted to remove them and use the LAG group. We also manually created the switch and the LAG group before running this switch.
The script accepts the input of a CSV which has 3 columns, pgName, numports, and vlanID. From there, I was able to do what I needed. The last step the script lists the Portgroups for validation.
