Script to Report ESXi Path Status to a SAN
Hey everyone - one of my customers was doing some maintenance on the FC switches recently and wanted an easy way to ensure that all of their ESXi hosts had 4 Active links to their datastores before bringing a switch down for maintenance. Sure, we can click through the GUI and manually examine each host... or we can automat it! So, I wrote a script to report the status of all paths to a given datastore (or datastores via wildcard matching) for all hosts that are connected to it! The usage on this guy is pretty straight-forward: .\report-datastorePaths.ps1 -datastoreName <name of datastore to examine; multiple datastores may be specified with wildcards> -alertThreshold <if the number of active paths is less than this number, alert the user> That -alertTreshold parameter (which defaults to 4) is used to cause the script to write to the host if it ever finds a host with fewer than that number Active links. So, if it doesn't spit out any red text, you're probably goo
