Chapter 4. Updating the firmware and licensing
This chapter describes how to determine the level of the firmware that is installed
on the switch, how to obtain the latest level of switch firmware, how to upgrade the
firmware, how to acquire additional feature licenses, and how to reset the switch to
activate the firmware upgrade.
Note: Configuration settings are lost during a firmware update. Before updating the
firmware, save a copy of the configuration on a separate device. In the event
of a failed update, the saved configuration can be restored. For more
information about the configuration file, see the
Application guide and
Command Reference for the switch.
Determining the level of switch firmware
After you install the switch in the IBM Flex System chassis, make sure that the
latest firmware is installed on the switch. To determine the level of the firmware that
is installed, complete the following steps.
1. Log on to the IBM Flex System Chassis Management Module (CMM) CLI as
described in the switch's User's Guide or CLI Reference Guide for the CMM. If
necessary, obtain the IP address of the management module from your system
administrator.
2. Set the environment to the bay where you installed the switch. For example:
system> env -T system:switch[1]
3. Issue the info command to display switch firmware information:
system:switch[1]> info
...
