And since SSH is disabled, according to VMware best practices, I had to search for a method to add vlan to the vswitch through command line. Some research yielded an interesting discovery. You need at least PowerShell 3. The command of interest in this scenario is New-VirtualPortGroup. This command creates a new VirtualPortGroup, i. Connect-VIServer vcenter Be warned: You should verify this script works in test environment and fully understand the commands prior to using it in a production environment.

Requires knowledge of vCenter, Cluster-name and what vSwitch needs to be configured. Have been working in the IT business since and have had network and security as field of focus since Your email address will not be published.

Leave this field empty.VMware provides a powerful and convenient graphical interface for managing ESXi servers — you can use a VMware vSphere Client that is a standalone application on Windows machines for managing ESXi hosts and the entire vSphere environment.

The majority of settings are available in the graphical user interface GUIthough sometimes you may need to get some information or change a configuration that is not displayed in the GUI. In this case, using the command line interface CLI is what you need — it is possible to configure all settings, including the hidden ones in the command line, which is also referred to as the console. Download a full-featured free trial of our product to explore its data protection capabilities right now and get an Amazon eGift card for your efforts.

VMware has made this restriction for security reasons. There are three main methods for enabling the command line interface in ESXi. You should enter your login and password after that credentials of the root user can be used.

Similarly, you can enable the console shell on a local ESXi host in the Services menu. You can also enable the ESXi shell in the Services menu. You need to enter the login and password of the ESXi user in this case root can be used by default. If you want to see the contents of the script, you can use the built-in text editor vi. If you are unable to remember a particular ESXCLI command related to the appropriate namespace, you can enter the command and see a tip in the output of the console—for example, type:.

By using the hardware namespace, you can view the full information about installed devices. Check the precise ESXi version and build number, including the number of installed updated and patches:. Notice that after setting a custom welcome message you will see only this set message on the black screen.

The custom message can be used for hiding information about your ESXi host on the display connected to the ESXi host when a user is not logged in. Display the information about IP addresses of the network interfaces that are present on the server:. List virtual switches and port groups:. The network namespace includes many commands. You can read the S.

A VIB file is similar to a container with zipped packages that can be installed in the system, with a descriptor and a signature file. The vm namespace can be used for operations on running virtual machines processes. You can kill the unresponsive virtual machine with ESXi shell commands. Shut down the VM by using the World ID displayed in the output of the esxcli vm process list command. If the soft command type was not helpful, consider performing an immediate shut down of the VM by using the hard method.

Only use this type of powering off the VM if the previous two types were unsuccessful. The ESXi shell commands list that may be useful for you is provided below. Convert a thick provisioned virtual disk to a thin provisioned virtual disk by using vmkfstools :. Among ESXi shell commands, vmkfstools is a powerful command for performing storage operations as well as managing storage devices, VMFS volumes, and virtual disks.

Read more about thick and thin provisioning as well as virtual disk shrinking in the blog post. After opening the task manager with the esxtop command, you can switch between tabs by pressing the appropriate keys:.

Replace the. For example, if you wish to find a diskname. Which method of creating a new user in the command line is better?Are you planning an ESXi upgrade? So I made a script that would output the build number and version number of ESXi hosts in a cluster. Keep in mind that you need to be logged in to the vCenter with PowerCLI before executing this obviously.

This will ouput something like this:. Explanation: The mechanism behind this is quite simple. What we are simply doing is outputting the values of those specific parameters. Need something fancier to share with your team or your superiors?

Please note that this CSV file will be created on the folder where the script is located. We have also parameterized the vCenter name and Cluster name for better versatility.

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. Running ESXi4. Obviously, this being a VM host, rebooting is the last resort especially since I'm remote to the machine. I'd also appreciate a pointer to a LiveCD I could use with this machine in case I do have to restart it which I could pass on to the person local to the host, so they can boot the system with the CD, gather a report, and send it over to me.

UPD: here's a screenshot of what things look like atm:. Or am I looking in the wrong place? It's an HP server, so there should be some information about the hardware available in the vSphere client. I'm not clear if you're saying you have access to the client or not, based on your question. If the server isn't the HP-specific build, the storage array information may be missing.

Do you know the model of the HP server? That can help narrow things down, as many of the recent units with Smart Array P controllers have flash-backed or battery-backed write cache BBWC installed.

But with the host's ssh shell, you can pull the server's product name and HP part number. At the shell prompt, type:.

Vmware Vsphere Command-Line Interface (CLI)

As for the disks and disk types comprising the array, the normal approach is to use the HP Insight Agents and use hpacucli when using a full OS, or one of the methods listed here. That's not an option under ESXi, though. You don't need a generic live CD to obtain full hardware specifications. The servers come with them. Running that will provide full insight into the hardware specs and RAID configuration. I'm sure there is a more elegant way, but to find out what kind of disks you have you can do an fdisk -l on the command line, and it tells you the model number and serial number of the disk:.

You may be able to get all of this information from within vCenter using the Hardware Status Page. Try to use esxcfg-info with -w key over ssh or console.

It command returns a lot of info, some of it is unique. Sign up to join this community. The best answers are voted up and rise to the top. How to find out more hardware details using only ESXi4. Asked 9 years ago. Active 4 years, 8 months ago. Viewed 91k times. Active Oldest Votes. That's good, but you need to look under "Health Status" in the upper-left of your screenshot. Either way, the server model number information will help with determining if the system was sold with a BBWC unit.Solutions provider takeaway : This chapter excerpt helps solutions providers to use VMware's command-line utilities for monitoring customers' performance and resource usage.

In addition to alarms and performance graphs, VMware also provides a couple command-line utilities to help with monitoring performance and resource usage. You can also monitor virtual machine performance using a command-line tool named esxtop.

A great reason to use esxtop is the immediate feedback it gives you after you adjust a virtual machine.

Monitoring vSphere performance with command-line tools

Figure I discuss that tool later in this section. Upon launch, esxtop defaults to showing CPU utilization, as illustrated in Figure At the top of the screen are summary statistics; below that are statistics for specific virtual machines and VMkernel processes.

To show only virtual machines, press V. Be aware that esxtop, like many Linux commands you'll find in the ESX Service Console, is case sensitive, so you'll need to be sure to use an uppercase V in order to toggle the display of VMs only. You can also see these counters in the virtual machine graphs, but with esxtop they are calculated as percentages. This might be the case if, for example, you've allocated two vCPUs to a virtual machine that really needs a single vCPU only.

While in CPU mode, you can also press lowercase e to expand a virtual machine's CPU statistics so that you can see the different components that are using CPU time on behalf of a virtual machine. This is quite useful in determining what components of a virtual machine may be taking up CPU capacity.

If you switch away to another resource, press C uppercase or lowercase to come back to the CPU counters display. At any time when you are finished with esxtop, you can simply press q lowercase only to exit the utility and return to the Service Console shell prompt. Remember, esxtop shows only a single ESX host. Making reservation or share changes while the virtual machine is currently on one ESX host may not have the desired consequences if the virtual machine is moved to another server and the mix of virtual machines on that server represents different performance loads.

To monitor memory usage with esxtop, press m lowercase only. This gives you real-time statistics about the ESX host's memory usage in the top portion and the virtual machines' memory usage in the lower section. As with CPU statistics, you can press V uppercase only to show only virtual machines. This helps you weed out VMkernel resources when you are trying to isolate a problem with a virtual machine.

The columns showing network usage include packets transmitted and received and megabytes transmitted and received for each vmnic or port. If a particular virtual machine is monopolizing the vSwitch, you can look at the amount of network traffic on a specific switch and the individual ports to see which virtual machine is the culprit. Unlike other esxtop views, you can't use V uppercase only here to show only virtual machines.

ESXi Commands List – Getting started

Like some other views, you can press V uppercase only to show only virtual machines. Those columns show loads based on reads and writes per second and megabytes read and written per second. The esxtop command also lets you view CPU interrupts by pressing i.

This command will show you the device s using the interrupt and is a great way to identify VMkernel devices, such as a vmnic, that might be sharing an interrupt with the Service Console. This sort of interrupt sharing can impede performance.

Another great feature of esxtop is the ability to capture performance data for a short period of time and then play back that data.The title says it all. You should always put hosts into maintenance mode when you do reboots, firmware updates, apply ESXi updates most patches require the host to be in maintenance mode or anything like that. During maintenance state the HA agent is disabled as well. This command is to know for sure.

After invoking the command, the host will start to enter maintenance mode, but waits until all VMs are suspended or migrated. Always put the host into maintenance mode. So the get command returns the actual state when checking if the host is in maintenance mode or not. Now, as you can see in the image above, I underlined another command — shutdown. This is obviously for shutting down the host completely. So once your host is in maintenance mode, it's safe to shut down. As you can see, with just a few commands you can safely put a host into maintenance mode and shut down.

Then you can do hardware upgrade or whatever you need to do. The VMware server will immediately reboot. Connect on: Facebook. Feel free to network via Twitter vladan. Do we have any esxcli command or any other cmd to enter the maintenance mode forcefully whn there is active vms present in the esxi host.
