Collect7: 7-Mode vFiler0 and vFilers Data Collector

It seems funny to be still writing PowerShell tools for Data ONTAP 7-Mode, but this one is actually very useful. You point it at your 7-Mode Controller, and it will collect all the config files and CLI outputs - for vFiler0 and any and all vFilers – and store the outputs in a folder per vFiler. A couple of examples of using it are below:

Example 1: Running as .\Collect7.ps1

Example 2: Running as .\Collect7.ps1 -System7M fas02 -UserName root -Password $PW

The Script

Copy into a text editor and save as Collect7.ps1. I’ve kept the script fairly compact. Edit the sections -
CONFIG FILES TO COLLECT
CLI OUTPUTS TO COLLECT
- as per requirements.
