Using IBM Storage Insights Pro and Alert Policies To Monitor Host Path Count

I was at a recent TechU event and had a discussion with a customer about using IBM Storage Insights to monitor host path count.  More specifically, the customer had a recent outage of a few hosts after doing some maintenance work on some storage and the affected hosts were not connected on all the expected paths.    There are options for using the storage data collections to review host connections. For instance, you could write a script that compares the SVC/Storwize host WWPN definitions to the connected devices to see if any WWPNs are not connected to the SVC.  However, it is much more straightforward to configure an alert in IBM Storage Insights Pro.   Alert Policies were previously covered in these two videos:  You can create an Alert Policy for an agentless host and then configure an alert to notify you when the path count changes.  You would need to create separate policies for each operating system, but after you create the first policy and define the alert, you can
