ESXi Commands Part-3 : Managing ESXi using esxcli commands

In this series we will see on how you can easily get information using commands in ESXi & how you can manage the ESXi using command line. This is the third part where we will see some of the basic commands on how you can administer & manage the esxi server using the esxcli. esxcli is the command line interface framework in vmware vsphere which provides modular architecture for the components “Namespace” running in VMkernel. esxcli is powerful command line interface which provides very helpful information. you don’t need to install any other software to run esxcli. esxcli can be directly run into the ESXi using Putty. Information you will find that can be very useful in the time of troubleshooting the esxi server issues.

In this post we will see on by using “esxcli system” how we can administer & manage esxi server . You may find very useful commands in this post which you will be using on daily basis using GUI from vsphere client but you can also do it using esxcli command line if you don’t have the vsphere client. Below is the list of things you can do to administer & manage the esxi server using esxcli. You will find some of the advanced management commands which should not be used if you don’t know about it properly.

Available Namespaces with esxcli system :

  • boot : It will give you the boot operations by which you can get the information about the host boot device & allow manipulation of VMkernel boot time configuration.
  • coredump : It will help you to do the operations pertaining to the VMkernel core dump configuration of file , network & partition. You can also create the coredump file for the system using this.
  • modules : It will help you to do the manipulation of VMkernel loadable modules & device drivers. You can do the operations such as load, list & setting options.
