Solution: This behavior is by design, and HP recommends that you do not copy the ROM components containing the unsupported versions in the HP SUM repository.

When HP SUM is launched, all the available versions of ROM components in the repository are listed under the Updates to be installed section of the Select Items to be Installed screen.

If a ROM downgrade is attempted from 2010.03.30 or later to 2010.03.01 or earlier with HP SUM on ProLiant G6 servers, the ROM components with the unsupported version are automatically removed from the updates to be installed. ROM components do not have the ability to block downgrades.
