Combining PowerCLI & ESXCLI to change PSP on a Large Scale

Using PowerCLI you can use Set-ScsiLun -MultipathPolicy “RoundRobin” to set the PSP, but I found it quite slow using it on a large scale. It would update one datastore on one host every 5 seconds.

Updating powershell help

When installing Powershell v3, it doesn’t install any local help files for get-help. If you are upgrading from v2 to v3, the help isn’t updated either. If you are using a proxy, a simple update-help may not work for you.
