This post follows on from my last, where I created a script to send an email report when running dedupe operations were detected.

Utilizing the same script, I made some quick modifications to have it send an email report of volume snapshots and their sizes/creation date. Here’s what it looks like.

The syntax for the report is pretty much the same as the last script.

.\NetApp-SnapshotReport.ps1 -Controller controller1,controller2 -Username <user> -Password <pass> -SMTPServer <server> -MailFrom <Email From> -MailTo <Email To>

Download the script here. I currently have it configured as a scheduled task running every morning so we have a daily report of current volume snapshots, and it works well.

Enjoy!

Hi all,

Recently ran across a misbehaving NetApp where it’s deduplication process would be triggered on a Saturday morning, and still be running come the Monday. It wouldn’t happen on every scheduled run, but when it did, it hurt storage performance significantly. We’re working on the usual tasks, there’s a lot of misaligned data on the volume. But in the meantime, I used the NetApp Data ONTAP PowerShell Module to create a little script that will shoot an email if it detects a running SIS process.

Configure it as a scheduled task on a system that has the DataONTAP powershell module installed. Here’s an example of the command line parameters:

.\NetApp-ActiveDedupeAlert.ps1 -Controller controller1,controller2 -Username <user> -Password <"pass"> -SMTPServer <server> -MailFrom <Email From> -MailTo <Email To>

If the script detects any running SIS processes, it’ll shoot off an email that looks like this:
