You can correct some of these conditions by using the functions accessible through the
Subsystem Management Window. However, for some of these conditions, you might need to
contact your IBM Customer Support representative. The storage management software
saves the information about the firmware upgrade process in log files. This action helps the
IBM Customer Support representative to understand the conditions that prevented the
firmware upgrade.
Note: The location where the firmware upgrade tool log files are saved on your system is
reported at the top of the firmware upgrade tool View Log window. See Figure 14-38 on
page 364.
Major and Minor firmware upgrades
A version number exists for each firmware file. For example, at the time of writing 07.70.16.01
is the current version number for the DS3500 firmware file. The first two digits indicate the
major revision of the firmware file. The remaining digits indicate the minor revision of the
firmware file. You can view the version number of a firmware file in the Upgrade Controller
Firmware window and the Download Firmware dialog. For more information, refer to the
Downloading the Firmware online help topic in the Enterprise Management Window.
The process of upgrading the firmware can be either a major upgrade or a minor upgrade
depending on the version of the firmware. For example, the process of upgrading the
firmware is major if the version of the current firmware is 07.70.16.01, and you want to
upgrade the firmware to a theoretical version 08.ab.cd.ef. In this example, the first two digits
of the version numbers are different and indicate a major upgrade. In a minor upgrade, the
first two digits of the version numbers are the same. For example, the process of upgrading
the firmware is minor if the version of the current firmware is 07.70.16.01, and you want to
upgrade the firmware to version 07.ab.cd.ef or any other minor revision of the firmware.
DS Storage Manager upgrade software
There are two seperate tools included in the DS Storage Manager software to update the
controller firmware and NVSRAM:
The firmware upgrade tool accessed from the DS Storage Manager (Enterprise
Management) window. This tool is able to perform staged firmware upgrades in which the
firmware is transferred to the DS3500 but the upgrade is not applied. This tool is able to
perform both minor firmware upgrades and major firmware upgrades. This tool is
described in section 14.5.4, "Using the Enterprise Management upgrade tool" on
page 363.
The firmware upgrade tool accessed from the DS Storage Manager (Subsystem
Management) window. In addition to the controller firmware and NVSRAM, this tool is also
used to update the ESM and drive firmware. This tool is not able to perform either staged
firmware upgrades or major firmware upgrades. This tool is described in section 14.5.5,
"Using the DS3500 Storage Manager (Subsystem Management)" on page 376.
Note: You also can use the command line interface (CLI) to download and activate
firmware to the DS3500 storage subsystems. For more information, refer to the About the
Command Line Interface online help topic in the Enterprise Management Window.
Table 14-1 on page 363 below lists the major differences in functionality between the DS
Storage Manager firmware update tools.
