How to Perform a License Rehost in the SIOS Licensing Portal
When a SIOS perpetual product license is first activated in the SIOS Licensing Portal, it is tied to a unique identifier that is local to that server. That unique identifier is typically a MAC address (which is also referred to as the system’s hostid) that is assigned to a Network Interface Controller (NIC). When this system’s unique identifier changes from the original unique identifier that was used to activate the license, a license rehost is required to continue using the SIOS Products.
A license rehost is a procedure that is required to activate an updated product license key when the system’s unique identifier (the MAC address/system’s hostid) no longer matches the original system’s unique identifier in the product license key.
When is a License Rehost required?
A rehost is required when the system’s unique identifier changes from the original unique identifier used to create the original license key. There are several things that can cause the unique identifier to change:
- The unique identifier may change as a result of a network configuration change in the current system.
- If the current system has failed and is being replaced by a new system, the system’s unique identifier will change and the product license key needs to be reactivated.
- The product license key needs to be reactivated if the current system is being upgraded to a new system.
What Problem occurs when a License Rehost is required
The most common problem that occurs when a license rehost is required is that the SIOS product will not start running properly. When this occurs the logs will show a failure due to an invalid license key because the license key that is installed on the system will not match the system’s unique identifier.
