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. If there were 10 ESXi hosts with 200 Datastores, that’s 2000 operations, at 5 seconds each, it adds up to 3 hours. The same can be done using ESXCLI extremely quickly, but it’s run on each host.
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.
Do the following:
$webclient = New-Object System.Net.WebClient$creds = Get-Credential$webclient.Proxy.Credentials = $credsupdate-help
This will connect to the internet and download the updated help files.
