Downloading the Controller Firmware or NVSRAM Packages
The storage management software lets you download or packages from the to all of the in the . Depending on the version of storage management software and model of controller that you are using, you might see different
interfaces when you download the package files:
Controller firmware download only with immediate activation
NVSRAM download only with immediate activation
Controller firmware download and, optionally, NVSRAM download with the option to activate both later
Attention:
Risk of application errors – If you do not have a on your application operating system, stop I/O activity to the storage subsystem before the download to prevent application errors.
Keep these important guidelines in mind before you begin downloading controller firmware or NVSRAM:
Use this option only under the guidance of a representative.
A version number exists for each firmware file. The version number indicates whether the firmware is a major version or a
minor version. You can use the Subsystem Management Window to download and activate only the minor firmware versions. However,
you can use the Enterprise Management Window to download and activate both the major firmware versions and the minor firmware
versions. For more information, refer to the Upgrading the Controller Firmware online help topic in the Enterprise Management
Window.
If a network problem occurs while the storage management software is polling a controller during a download, an error message
might appear, which indicates that the download could not complete. Although the download might have successfully completed,
the storage management software was unable to verify the success of the operation, which results in the error message. Perform
these steps to verify that the download successfully completed.
Turn off the power to the controller module, and then turn on the power again. Wait until the storage subsystem has finished
initializing (this might take several minutes).
Obtain the current firmware version by selecting Storage Subsystem >> View >> Profile. The storage subsystem profile appears.
Select the Controllers tab. If the firmware listed does not match the version that you tried to download, retry the download.
When you download new firmware or NVSRAM, the storage management software checks the operating status of the controllers in
the storage subsystem. If any controllers are not in status, an error message dialog appears. You are given the opportunity to stop or continue the download. Before continuing,
correct any non-Optimal condition. If you choose to proceed with the download, the code on the non-Optimal controller might
not be synchronized after the non-Optimal condition has been corrected. If the firmware is not synchronized, you might need
to download the firmware again.
