VMware vSphere ESXi Commands for everyday use

In this post, I tried listing down all commands that I use everyday for ESXi Troubleshooting. I have categorized the commands for easy accessibility.

I find these commands are very useful when the ESXi host disconnected from vCenter and when not able to connect to vSphere Client.

To get All registered VMs on the Host:
vim-cmd vmsvc/getallvms

Example:

~ # vim-cmd vmsvc/getallvms
Vmid Name     File                                  Guest OS Version       Annotation
1    DeskTop  [datastore1 (3)] DeskTop/DeskTop.vmx  windows8_64Guest       vmx-08
2    Domain   [datastore1 (3)] Domain/Domain.vmx    windows7Server64Guest  vmx-08
3    VCD55    [datastore1 (3)] VCD55/VCD55.vmx      centos64Guest          vmx-08
Power ON a VM:
vim-cmd vmsvc/power.on <VMID> 

Example:

~ # vim-cmd vmsvc/power.on 3
Powering on VM:
Power OFF a VM:
vim-cmd vmsvc/power.off <VMID> 

Example:

~ # vim-cmd vmsvc/power.off 3
Powering off VM:
 Gracefully shutdown a VM’s Guest OS:
vim-cmd vmsvc/power.shutdown <VMID> 

Example:

~ # vim-cmd vmsvc/power.shutdown 3
~ #
Register a VM
vim-cmd solo/registervm <vmxpath> 

Example:

~ # vim-cmd solo/registervm "/vmfs/volumes/datastore1 (3)/VCD55/VCD55.vmx"
4

UnRegister a VM:
vim-cmd vmsvc/unregister <VMID>
