secd.netlogon.noServers: None of the Netlogon servers configured for Vserver
This was an easy fix, scouring the web for answers made it more difficult.
Scenario- Transition from 2012 Active Directory to 2019 Active Directory.
Run this command #vserver cifs security show -vserver servername
Solved! See The Solution
Adding point to above inputs:
From 9.3 cifs architecture has changed and default protocol will be used highest SMB version to communcate for AD connections. Below KBs might be helpful for quick reference. Also, there is a known bug below shared KB listing and as per the last update though it says fix available in 9.6, came to know fix is not available even in 9.6p12. Hence if there is similar alerts please, please take confirmation from netapp to reproduce the issue in their lab.
EMS error: secd.*.noServers:EMERGENCY - NetApp Knowledge Base
We were seeing other secd alerts related to lsa, ldap even in 9.7p12. There is some service which is actually trying to contact AD and it is failing. which lead to the alerts. Just sharing for your reference. Any update or workaround or fix available....please keep posting friends.
From 9.3 LDAPS will be in disabled state by default. Need to understand if we will enable this option as per above article any impact to current active operations on the SVM serving CIFS shares, when LDAP client is not configured to use AD LDAP.

Yet to verify or reproduce the issue by engineering team with below environments:
1)AD servers window2016 *5 qty
Configure SVM with Active directory.
No AD ldap or ldap client configured required.
No preferred DCs were configured.
2)AD server with windows2008 and windows2016
Configure SVM with Active directory.
No AD ldap or ldap client configured.
No preferred DCs were configured.
Good research. Additionally, default settings for SMB 1.0 and 2.0 connections to domain controllers also depend on the ONTAP version. The system default for ONTAP 9.1 is enabled for SMB 1.0 and disabled for SMB 2.0. The system default for ONTAP 9.2 is enabled for SMB 1.0 and enabled for SMB 2.0. If the domain controller cannot negotiate SMB 2.0 initially, it uses SMB 1.0.
