Downloading the Firmware and the NVSRAM (Activate Now or Later)
Use this procedure to download the controller firmware and, optionally, the .
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 this procedure 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.
You might choose to activate the files immediately or wait until a more convenient time. You might want to activate the firmware
or NVSRAM files at a later time because of these reasons:
Time of day – Activating the firmware and the NVSRAM can take a long time, so you might want to wait until I/O loads are lighter. The
controllers will go offline briefly to load the new firmware.
Type of package – You might want to test the new firmware on one storage subsystem before loading the files onto other storage subsystems.
Important:
The ability to download both files and activate them later depends on the version of storage management software and the type
of controller in the storage subsystem.
Note:
You can use the command line interface to download and activate the firmware to several storage subsystems by using a script.
For more information, refer to the Using the Command Line Interface online help topic in the Enterprise Management Window.
The Current version area lists the current firmware and NVSRAM versions in use by controllers in the storage subsystem.
To locate the directory in which the file to download resides, in the Select Files area, click Browse next to Selected firmware file.
From the File Selection area, select the package file to download, by double-clicking the file.
By default, only the downloadable files that are compatible with the current storage subsystem configuration appear.
When you select a file in the File Selection area of the dialog, applicable attributes (if any) of the file appear in the
File Information area.
If you want to download an NVSRAM file with the firmware, make sure that the Download NVSRAM file with firmware check box is selected, and click Browse next to the Selected NVSRAM file check box to add the file as described in step 2.
To upload the files to the controller without activating them, click Transfer files but don't activate them (activate later).
Click OK.
Keep these guidelines in mind:
If the OK button is inactive, make sure that you have either specified an NVSRAM file or you have deselected the Download NVSRAM file with firmware check box.
If the file selected is not valid or is not compatible with the current storage subsystem configuration, the File Selection Error dialog appears. Click OK to close it, and choose a compatible firmware or NVSRAM file.
In the Confirm Download dialog, click Yes.
The download begins. For more information about download progress, refer to the Monitoring the Status of the Download online
help topic.
