This knowledge base article addresses a newly introduced alarm, “High pNic error rate detected,” triggered on ESXi hosts after upgrading to vSphere 7.0 U2 or later. It explains the purpose of the alarm, which monitors network metrics related to pNICs used for vSAN traffic. The article outlines the specific metrics and their corresponding warning and critical thresholds that can trigger the alarm. It also emphasizes that if these thresholds are exceeded, the cause should be investigated in the physical network, with a note that some alarms may be due to special network frame length mismatch packages that can be safely ignored.
This knowledge base article provides a step-by-step guide to address a situation where vCenter Server loses network connectivity after an unplanned or planned outage. To resolve this, the guide assists in building a temporary Standard Switch to reconnect vCenter and recover network access. The impact mentions the need for at least 2 vmnics and considerations for LACP configurations. The resolution involves multiple steps, including removing a vmnic from the DVS, creating a Standard Switch, connecting vCenter to it, migrating vmnic and vmk back to the DVS, and finally deleting the temporary Standard Switch.
This knowledge base article offers an overview of the different licensing editions of VMware NSX-T Data Center 3.2.x and provides a detailed list of features associated with each edition. It distinguishes between several editions, such as Professional, Advanced, Enterprise Plus, and Remote Office/Branch Office, offering an in-depth look at networking, distributed security, gateway security, NSX Intelligence, load balancing, NSX Cloud for AWS and Azure, modern apps, automation, and platform features. The article serves as a comprehensive reference for understanding the feature sets available with each licensing edition of VMware NSX-T.
This KB article addresses network connectivity issues in Windows Virtual Machines (VMs) caused by problems with the Broadcom bnxtnet “async” driver version 224.0.x.x or later for VM uplinks. VMs suddenly lose connectivity to certain network destinations, and the vmxnet3 vNIC generates a “hang detected” message in the ESXi kernel logs. This issue may lead to intermittent network loss. The resolution involves updating the Broadcom drivers to versions starting with 226.0.145.4-1, with a recommendation to verify compatibility with the specific NIC model via the VCG (HCL) or OEM resources.
This article addresses issues related to expired or self-signed certificates on NSX-T Managers and the NSX-T VIP. The problem causes alarms and workflow failures across multiple operations, especially those involving the SDDC Manager. To streamline the process of replacing these certificates, a script is provided for automation. The script significantly reduces the time and effort required for the certificate replacement process, which would otherwise take around 30 minutes to a 3-second workflow. The article also includes instructions on how to run the script on a vCenter affiliated with the NSX-T Managers, allowing you to replace certificates on both NSX-T Managers and NSX-T VIPs efficiently.

This knowledge base article addresses a specific issue that occurs during an NSX upgrade. After the pre-check stage, an error message is encountered for an Edge Node, indicating that the Edge node’s vmID is not found on the NSX Manager. This issue leads to the Edge node being stuck during the upgrade process, particularly at the “switch_os” step. The purpose of the article is to provide a resolution and workaround for this problem.
This knowledge base article addresses a situation where an alarm is triggered in the NSX-T UI, indicating that an application on an NSX node has crashed. The alarm provides guidance on collecting a support bundle, including core dump files, and contacting the VMware Support team. The article also highlights the log messages in /var/log/syslog.log and /var/log/nsx-syslog.log that correspond to the application crash.
This knowledge base article addresses a scenario where ESXi hosts are not correctly removed from an NSX-T environment, leading to issues such as hosts not appearing in the Host and Cluster section of the UI and causing upgrade pre-check failures. These stale host entries in the NSX-T database can disrupt the upgrade process and prevent successful host removal via API calls. The article explains the cause, which is improper host removal, and offers resolutions, including following the correct procedure for host removal or contacting VMware support for assistance. This article is relevant for NSX-T administrators dealing with host removal and upgrade challenges.
This KB offers a detailed guide to HCX Bulk Migration, outlining its various stages and providing insights into placeholder disk creation, synchronization, switchover, image generation, and cleanup. The article also covers monitoring the migration process through log analysis. Additionally, it presents essential migration best practices, such as enabling “Seed Checkpoint,” quiescing VMs, ensuring adequate target datastore space, and more, to help users enhance the success of their migration efforts and efficiently manage the process. It serves as a comprehensive resource for those looking to gain a deep understanding of HCX Bulk Migration and improve their migration procedures.
This knowledge base article addresses a specific issue that arises after upgrading to ESXi 7.0U3l (build 21424296), where the Load balancing configuration on vSwitch port groups can get overridden to route based on originating virtual port under certain conditions. The cause is detailed, primarily focusing on scenarios where the Teaming and Failover settings result in this override. The potential impact of this issue is highlighted, emphasizing that it affects vSphere Standard Switches. The article provides information about resolutions and workarounds, including upgrading past ESXi 7.0 Update 3M or manually resetting Load balancing settings at the port group level. It also refers to related information for further context.
