4.4.1 Management of a License
0025-5328
Overview
1. Validate an optional function which has been installed but has not been validated based on the license key issued by a license issue server (hereinafter called
"LMS").
2. Invalidate the function for which a license has been already set up.
Details
1. Validate a license by entering the license issued by LMS via the local UI.
2. The license key issued by LMS cannot be entered via the remote UI.
3. Invalidate a license (Set the function to OFF) via the service mode.
4. Validate a license via the service mode.
5. A license with restriction (with an expiration date, restriction in the number of licenses) is not supported. (Restriction information is not read.)
6. Some optional functions installed are in dependent relationship with each other. For example, when using [Function A], [Function B] should be available. In this
case, [Function B] is called a slave option of [Function A]. Installation of the slave option fails when it is found that the master option is not validated as a result of
verification of the dependent relationship.
7. Decoding and verifying a license key
Decode an entered license key and examine the validity of the license information obtained. When an error occurs during verification, the error information is sent
back to the local UI, which displays an error message based on the information.
Verification errors are assumed to occur in the following cases.
- When a license is installed in a non-licensed device
- When an optional function included in the license does not exist in the target device
- When an optional function included in the license is a slave option and a master option is not validated
- When an incorrect license key is entered
- When a license key is illegally altered
8. The PCL license is in a dependent relationship with the BarDIMM license as indicated in 6. Unless the PCL function is validated, the BarDIMM license cannot
be added.
(1) PCL/BarDIMM OFF
The BarDIMM license cannot be added.
The PCL license can be added.
(2) PCL ON/BarDIMM OFF
