Loading a UCS file with the no-platform-check option does not bypass the platform check (which it should).


The user cannot load UCS files from other platforms. The system posts the following error message: ERROR: The platform on the system is different from the platform in the UCS. Can't install the UCS. To bypass platform check, use no-platform-check option.


This occurs when using the no-platform-check option to load a UCS file from a different platform. This issue occurs only in version 11.6.0 (the base software), 11.6.0 HF1, 11.6.0 HF2, and 11.6.0 HF3.


On the system where you are installing the UCS, use tmsh to run the following commands: -- modify sys db ucs.platformcheck value false. -- load sys ucs my_ucs_filename.

Fix Information

The no-platform-check option now bypasses the platform check, which allows the user to load UCS files from other platforms.
