I hope everyone is as satisfyingly full on food, friends, and family as I am. As an early gift to myself, I’m writing a PowerShell script that utilizes NetApp’s PowerShell Toolkit. The script will help me quickly determine current volume and LUN settings so I can see what LUNs are at risk of going offline due to out of space conditions. In scripting tradition, I couldn’t find anything online that did exactly what I wanted so I rolled my own!
Here’s what the output looks like. The column names are abbreviated because I expect to have several more columns. The abbreviations are, Volume Thin Provisioning, Fractional Reserve, Snapshots, Volume AutoGrow, Snapshot AutoDelete.
