Installation options
You can specify firmware upgrade behavior for installable components by selecting one or more options
from the Additional Options field.
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.
The following table illustrates how changing the options for firmware upgrade behavior changes the
firmware upgrade results. In this example, the array controller is assumed to be an HP Smart Array 6402
controller.
If the existing array controller has firmware version 3.00 installed, then updating the firmware produces
the following results.
Default Allow downgrades Allow rewrites
Firmware upgrade v3.05 3.05 3.05 3.05
Firmware upgrade v3.10 3.10 3.10 3.10
If the existing array controller has firmware version 3.10 installed, then updating the firmware produces
the following results.
