How to restart vpxd service in vcenter appliance?
The VMware ESXi is a part of the vSphere platform. There can be issues with all of the software. You may not be able to connect to an ESXi host or to a vCenter host in vSphere, for example, if you see error messages in the virtual machine environment. Some cases restarting the host can help.
It is a problem in a production environment if you have to shut down virtual machines or move them to another host. It is better to restart the management agents first. It's very likely that restarting management agents on an ESXi host will resolve the issue.
Let's start by listing the symptoms that need to restart ESXi management agents.
Virtual machine creation may fail because the agent can't retrieve options from the host.
Relocate a virtual machine.
The current connection state of the host prevents the operation from being allowed.
0 MHz is the maximum usage of the processor.
The memory usage was less than 1 MB.
ESXi management agents are used to make it possible to access an ESXi host from a vCenter server
The default configuration has VMware agents installed. Hostd and vpxa are the main agents on the ESXi host and may need to be restarted if there is a problem with the host.
Hostd is a host agent that manages most of the operations on a host. ESXi and vmkernel communicate with the help of VMware hostd.
When the ESXi host joins the vCenter server, vpxa is activated. There is an instance in which vpxd is running on the vCenter side and vpxa is running on the ESXi side. The intermediate service for communication between hostd and vCenter is called vpxa.
The vpxa process on the ESXi host allows vCenter to give commands to the ESXi host. If you connect directly to an ESXi host to manage it, then communication is established directly to the host process.
You don't need to restart virtual machines when you restart management agents.
If you want to make sure that the VMs are not affected, try to ping one of the VMs running on the ESXi host and restart the agents on the ESXi host. There are tasks running on the hosts. If you restart the management agents on the ESXi host, make sure that there are no VMware backup jobs running on the host.
The ESXi host and VMs on that host are displayed as disconnected for a moment while the management agents are on the ESXi host. After a few seconds, refresh the page in the vSphere Client to see the status of the ESXi host and the VMs.
If you use vSAN, NSX, or shared graphics in your virtual environment, read the precautions at the end of the post before restarting the agents.
The most reliable way to restart management agents is using the DCUI.
You need to have a keyboard and monitor on the server. You may not be able to manage a host remotely using services used for ESXi network management.
It is convenient to restart the vpxa agent using the host client.
If you can't open the Host Client, use other methods to restart the agents. You can use the T SM-SSH service to access the ESXi host.
The ESXi command-line interface is a powerful tool for managing and resolving issues.
The ESXi host needs to be managed remotely with the help of the SSH access. You can use an SSH client to connect to an ESXi host. You can use a Windows machine with a putty client. To enter administrative credentials in the SSH client, you need to define the ESXi server's address or hostname, select the port, and then enter your credentials. You should see the console session via the internet.
If you want to use ESXi shell directly, you need to enable it and use a keyboard and monitor on the server. You can learn more about the command-line options of ESXi by reading the post.
Commands used in this post are compatible with the newer versions of ESXi.
The vmk0 interface is used on ESXi If you have a different name for the management network interface, use the appropriate interface name in the command.
Two basic commands are separated by a semicolon. The first part of the command disabled the vmk0 management network interface.
The second part of the command is executed when the first part is executed and vmk0 is down. The management network interface was restarted.
You can open the DCUI in the SSH session if you have access to the host's server. The method allows you to use a pseudo-graphical user interface in the console for more convenience.
The issue is discussed in the following post.
Signing a certificate is not a valid security token service certificate.
There are notes.
You can log into the vSphere Web Client as the vSphere SSO domain administrator.
Select Administration from the home menu.
Go to Single Sign-On. Click on the certificate tab and then click on the signing button.
The cert. expiration dates can be found in the Valid to column.
The following article shows how to verify that the security token service cert has expired.
There is an article on thevmware.com
Is that correct?
You can copy files via WinSCP if you enable the BASH.

The vCSA is a building block of the modern environment. This product is very easy to deploy and manage and is the main feature of a vSphere environment. The main function is embedded into a single location.
This platform is now running on a lightweight Linux environment with a minimal footprint and a distribution from VMware. This might make some users uncomfortable. There is a small learning curve starting with this basic post on how to manage the principal vCenter services.
The administrators of the VMware vSphere environment have always used a vCenter server on a Windows server. The switch to a new platform based on Linux might not be easy for some, though most management options are available through the graphical user interface.
You can access the interface using two different methods.
The appliance shell will need to be enabled through the applianceMUI. To do this, log in to vCSA as root and go to Access > Edit, then select BASH shell and enable SSH login
You can log in with your preferred client via SSH.
You can type shell after login.
The list of services may be different depending on the deployment type, for example, a vCenter appliance, an external Platform Services Controller (PSC), and also for an embedded vCSA. This command is used to list all services.
The above command only lists the available services.
You can enter the following command to check the status of all services.
If you want to know the status of the main vCSA service, you would type this:
The following command is needed to start a service.
To stop a service.
Sometimes it is necessary to stop and restart services installed on this vCSA based on the roles they are in.
You can stop all services with this command.
execute this command to start all services in the current profile.
The process of starting all services takes time because it manages internal dependencies.
It can take five to six minutes to start all services in my lab environment.
The vCSA services are not a separate service under the Windows Service Control Manager but are part of the VMware Service Lifecycle Manager service.
You can list all services and their statuses on the web. This is the easiest way to go. Go after login.
System configuration is included in the administration.
The HyperFlex vCenter registration failure issue is described in this document.
The EAM service can't log in after a new certificate is issued.
Contributed by Ignacio Orozco, an engineer with the company.
When you try to re-register the Hyperflex cluster in vCenter, you may see an error.
There is a connection error between the two.
The EAM services can be started from the vSphere area. Click again to try cluster creation.
You can see this in the stMgr.log.
In the VCSA file: /var/log/vmware/eam/eam.log OR the VC in the C:\ProgramData\VMware\vCenterServer\logs\eam\eam.log file on Windows Server for ESX Agent Manager (EAM), you will see entries similar to:
