Installation options
You can specify firmware upgrade behavior for installable components by selecting one or more options

CAUTION: Updating the firmware while a shared device is in use can lead to data loss.
Before enabling the Allow Shared Devices option, be sure any other servers sharing the
selected devices are offline.
• Select Allow Downgrades to downgrade the current firmware to an older version.
• Select Allow Rewrites to enable HP Smart Update Manager to overwrite the current firmware version
with the same version.
• Select Allow Shared Devices to upgrade firmware in a shared storage environment.
NOTE: HP Smart Update Manager does not support Allow Downgrades or Allow Rewrites for
the HP Virtual Connect Ethernet and Fibre Channel Modules for c-Class BladeSystem firmware
component.
