Current Version:  1.5   Clustered Data ONTAP (also known as ONTAP) uses self-signed certificates by default for management of the environment. These certificates have a typical expiration date of 1 year (365 days). This KB describes the process to recreate the certificates: https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_renew_an_SSL_certificate_in_ONTAP_9   This script handles the steps outlined in the article by doing the following: Connecting to a cluster Collecting all existing certificates Ensuring the certificate is self-signed Deletes the self-signed certificate Creates a new certificate with the same properties as the previous one with a 10 year expiration Configures SSL on the SVM to use the new certificate   Article link updated by Admin on Sept 29, 2020. ...

I am trying to script the snapmirror failover process using PTK.   When I run the following set of commands, # Update Existing SnapMirror and then Break it off Invoke-NcSnapMirrorUpdate -Controller $DstCtrl -DestinationVserver $DstSVM -DestinationVolume $DstVol -ErrorAction stop Watch-Command { Get-NcSnapMirror -Controller $DstCtrl -DestinationVserver $DstSVM -DestinationVolume $DstVol | Select Status } -Until "idle" Invoke-NcSnapMirrorQuiesce -Controller $DstCtrl -DestinationVserver $DstSVM -DestinationVolume $DstVol -ErrorAction stop Watch-Command { Get-NcSnapMirror -Controller $DstCtrl -DestinationVserver $DstSVM -DestinationVolume $DstVol | Select Status } -Until "quiesced" Invoke-NcSnapMirrorBreak -Controller $DstCtrl -DestinationVserver $DstSVM -DestinationVolume $DstVol -Confirm:$false -ErrorAction stop   the Invoke-NcSnapMirrorBreak sometime returns with an error: Invoke-NcSnapMirrorBreak : Another SnapMirror operation is in progress. At Z:\Software\NetApp\Powershell Toolkit\Scripts\SnapMirror-Reverse-v3.ps1:119 char:1 + Invoke-NcSnapMirrorBreak -Controller $DstCtrl -DestinationVserver $Ds ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (apfas8200:NcController) [Invoke-NcSnapmirrorBreak], EANOTHER_OP_ACTIVE + FullyQualifiedErrorId : ApiException,DataONTAP.C.PowerShell.SDK.Cmdlets.Snapmirror.InvokeNcSnapmirrorBreak   Why does it report another operation is in progress?  I just checked the status, and it was quiesced. It does not fail every time it runs, just some of the time.  I have many snapmirrors where I perform this operation repeatedly.  Many work just fine and then others seem to fail nearly all the time.  I can sometimes just resume the snapmirror and start the script again and it runs without any issues on the same snapmirror.   Is there some code I can add to check and try again... like maybe 3 times before aborting?   Or better yet, does anyone know what I am not doing correctly to make sure the snapmirror is not performing another operation before I request the snapmirror break? ...

Given the quick and enthusiastic response to the Netapp Powershell Toolkit I'm surprised to see no scripts in here. Mine's pretty basic but at least I get to be first! This script will simply pull out details of all snapshots over a specified age from a list of filers and send an HTML formatted email to a list of recipients. Obviously it can easily be scheduled for regular reporting. Thanks to fjohn for the snapshot code - as a Powershell newbie I'd probably have struggled with that. Regards, Ed. ... View more
