Upgrade Controller Firmware
Select this option to upgrade the firmware of the controllers in the storage subsystem. In the
process of upgrading the firmware, the firmware file is downloaded from the host to the
controller. After downloading the firmware file, you can upgrade the controllers in the storage
subsystem to the new firmware immediately. Optionally, you can download the firmware file to
the controller and upgrade the firmware later at a more convenient time.
The process of upgrading the firmware after downloading the firmware file is known as
activation. During activation, the existing firmware file in the memory of the controller is
replaced with the new firmware file. The firmware upgrade process requires that the
controllers have enough free memory space in which the firmware file resides until activation.
Upgrade Controller Firmware window and the Download Firmware dialog. is shown in
Figure 6-7.

You also can use the command line interface (CLI) to download and activate firmware to
several storage subsystems.
Note: We recommend that you use the load configuration file option for new DS3500s that
you want to configure similarly to an existing DS3500. For example, if you have a number
of storage subsystems with similar configurations, you can configure one, save the
configuration file, modify it if necessary (for example, to use a different storage subsystem,
or define different hosts), then use it to quickly configure the remaining storage
subsystems.
You could also use this option to re-create replacement DS3500s if your original hardware
was destroyed in a disaster.
Existing configurations: The script will not overwrite an existing configuration, that is, the
script will fail if it attempts to build an array using drives that are already part of an existing
array.
However, if you have lost an array that had data stored on it, do not reapply the
configuration using this script; it will initialize the drives and delete the data. Instead, you
should contact IBM technical support to see if your data can be recovered.
