Hello @saleff
Try checking the ESXI hosts individually and see if you are able to find the VM.
1) Web UI
a) Browse to the ESXI host using http://host-name/ui or http://host-IP-address/ui
b) Search for your VM in the inventory. If not visible , check for any VM with the state Invalid.
c) If there is , remove the Invalid VM and then try to re-register.
2) Command line :
a) SSH to each ESXI host and search for the VM.
vim-cmd vmsvc/getallvms grep -i vm_name ------------------------------------------> This should give the valid name of the VM with a valid VMID
b) Check if there is any message for "Invalid VM 'VMID'" after running the above command.
c) If there is any Invalid VM , remove the VM using the following command and then re-register :
vim-cmd vmsvc/unregister <VMid>
d) You can also check the inventory.xml on the ESXI Hosts for the list of registered VMs :
Command : cat /etc/vmware/hostd/vmInventory.xml
