Esxcli command to restart the virtual machine

If one of the vm under the esxi crashes and the console of the esxi cannot be used, in order not to affect the normal use of other vm under the same esx, we can only restart the vm separately with the command line to ensure security and efficiency. This method can be used in esxi5.1-exsi6.5 versions.

First of all, to install the exsi virtualization software host through ssh login, you need to enable ssh (usually off by default), and enable the ssh service as follows

You can also enter it by connecting the monitor through the control port or the computer room, and then pressing alt+f1 to enter the password.

You can then use your own exscli command tool to turn off vm

Esxcli vm process list

Get information about running virtual machines

Vm process kill-type=hard-world-id=245735

Disable the virtual machine. World-id is the virtual machine ID that is queried.

Note that there are three modes of shutting down the virtual machine: soft is the lowest, hard is executed immediately, and force mode can only be used if it still cannot be shut down.

Check to see if the virtual machine has been turned off: esxcli vm process list (this command shows that if it is not in the list, it has been turned off)

Delete orphaned virtual machines in vcenter

In practical use, you should be no stranger to (isolated) virtual machines, sometimes they are automatically generated by faults, and there are also virtual machines where vsphereclient directly logs into physical servers, but they will be isolated in vcenter, and many people may not find out how to delete them at once.

Powder screen after exsi6.5 installation

When installing exsi6.5 or 6.7using a second-hand server or a compatible server, the pink screen appears during or after the installation, as shown below:

Or

These problems are generally caused by the incompatibility between the version of exsi and the server.

Go to the official website to download a free and compatible version

Https://my.vmware.com/en/web/vmware/evalcenter?p=free-esxi6

You can sign up for an account and download it for free. Most servers are compatible.

If you are interested, you can study the error log of the pink screen to troubleshoot, most of which are hardware compatibility issues.

The solution of datastore error reporting Fail to create VMFS datastore created by ESXi

In some cases, such as using a second-hand server to install esxi without using a new hard disk, or if the hard disk does not fully write 0 to clear data, it cannot be added as a local disk to exsi when it is used, and it will prompt an error when creating a new data warehouse datastore in VMware vShere/ESXi. The error message shown in the following figure pops up! "Fail to create VMFS datastore VMFS xxxx"-cannot change the host configuration (cannot create VMFS, cannot change host configuration)

Log in to your VMware vShere/ESXi host using SSH or Telnet, and then run the following command

Ls-lha / vmfs/devices/disks/

All storage partitions are listed, and then the id number of the partition where the creation failed is copied. My example is the one marked in red below.

Then enter the copied id after the following command:

Unable to add hard drive number found in partedutil getptbl / vmfs/devices/diks/naa.xxxxxxx #

Next, use the following command to fix it:

Partedutil setptbl / vmfs/devices/disks/naa.xxxxxxx

Through the above fix, go back to the VMware vShere/ESXi host again to create datastore and there will be no more errors!
