Today my lab evalaution license was end with 0 days remaining; I found good way to reset your VMware licence evaluation mode back to 60 days so you can use it for more 60 days & reset again after 60 days.
now there is no need to format / reinstall your ESXi & vCenter to reset your licence.
Note: I will not suggest this to use in your production environment but you can use it for your lab.
here are the steps below:
Reset licence on ESXi host:
A) For ESX 4 & ESXi 4 , 5
- Login to the TSM through SSH or Shell
- Remove the following two files:
- /etc/vmware/vmware.lic
- /etc/vmware/license.cfg
- Reboot server
use below command to do the task
# m -f /etc/vmware/vmware.lic /etc/vmware/license.cfg
#reboot
B) For ESXi 5.1, 5.5 & 6
For ESXi 5.1 and ESXi 5.5, you may need to continually remove the license files as the server reboots for this to work. The following should do this quite nicely:
--------------------------------------------------------------------------------------------------
rm -f /etc/vmware/vmware.lic /etc/vmware/license.cfg
reboot ; while true ; do
rm -f /etc/vmware/vmware.lic /etc/vmware/license.cfg
done
An alternative shows that restarting the services should works just as well as rebooting the server:
# For ESXi 5.0
rm -f /etc/vmware/vmware.lic /etc/vmware/license.cfg
services.sh restart
# For ESXi 5.1
rm -r /etc/vmware/license.cfg
cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
/etc/init.d/vpxa restart
The alternative also shows a method for resetting the trial license while connected to vCenter server. I still think removing and re-adding the ESXi server is cleaner.
Update: 25/08/2015
use below command for 5.1
rm -r /etc/vmware/license.cfg
cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
/etc/init.d/vpxa restart
use below command for 5.1
rm -r /etc/vmware/license.cfg
cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
/etc/init.d/vpxa restart
Reset ESXi Licence
