Firmware updates
To update firmware, use the HP BladeSystem c-Class Virtual Connect Support Utility v1.9.0. For more
information on updating the firmware, see the HP BladeSystem c-Class Virtual Connect Support Utility
documentation on the HP website ( http://www.hp.com/go/vc/manuals ).
The following role operations are required to perform firmware updates: Firmware Update, Save Domain
Configuration, and Export Support Information. For more information on role operations, see "Role
Management (Role Operations) screen (on page
84 )."
Virtual Connect v4.20 does not support the HP 1/10Gb Virtual Connect Ethernet Module, the HP 1/10Gb-F
Virtual Connect Ethernet Module, nor the HP 4Gb VC-FC Module. If your domain contains these modules,
you cannot update to VC 4.20.
To help ensure proper operation, clear the browser cache and reload the browser after firmware updates.
The firmware downgrade process changed as of VC v3.70 and VCSU v1.7.0. The following table describes
the circumstances in which downgrading VC firmware requires deletion of the domain.

Domain deletion is not required when a firmware downgrade is performed to a firmware version that existed
prior to the firmware upgrade. However, if no previous firmware upgrade has been performed,
downgrading without domain deletion is not allowed. When attempting a firmware downgrade, consider
the following:
• Multiple, consecutive firmware downgrades are not supported.
• A same version upgrade does not prevent a future downgrade if you decide to downgrade to the
previous version in the future.
• You can perform a firmware downgrade only to a version that was installed on the primary VC module
prior to the upgrade.
