HP ProLiant G6 Server ROM downgrade from 2010.03.30 or later to 2010.03.01
or earlier with HP SUM is not supported
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.
For HP ProLiant G2, G5, and G6 servers, after upgrading to the May 2011 (or later)
revision of the system ROM, perform special steps if downgrading the system ROM
to revisions earlier than May 2011 is required
The May 2011 (and later) revisions of the system ROM for the HP ProLiant G2, G5, and G6-series
servers listed in the support document (see hyperlink below) include enhancements to the system
ROM flash update process. These enhancements improve the reliability and security of System
ROM updates by reducing the possibility of unexpected corruption of the flash part.
Because these enhancements require modifications to both the System ROM and the flash update
utility, the May 2011 (or later) System ROM cannot be downgraded using the flash components
available on the HP Support site that are dated earlier than May 2011.
Solution: The system ROM can be downgraded by creating a new flash component using an older
system ROM revision. For more information on how to downgrade the system ROM, see the HP
support website at http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?
