Ping All LIFs and SPs on my Cluster Tool

An update to Ping All LIFs on My Cluster Tool now including Service Processors also (but it will still work against SIMs that don’t have SPs)!

Image: Example run against a test physical 2-node cluster

Copy and paste the below script into a text file and save as say PingAll.ps1. Then run as:

PS C:\ > .\PingAll.ps1 -Cluster {CLUSTERNAME} -Username {USERNAME}
