Upgrading and downgrading firmware (which is nondisruptive) the system. After the system boots up, the new firmware is activated. The firmware download process then copies the new image from the primary partition to the secondary partition. In dual-CP systems, the firmware download process, by default, sequentially upgrades the firmware image on both CPs using HA failover to prevent disruption to traffic flowing through the Backbone. This operation depends on the HA status on the Backbone.
Considerations for FICON CUP environments then you must export the public key to the remote host. Before running the firmwareDownload command, you must first configure the SSH protocol to permit passwordless logins for outgoing authentication as described in the Configuring outgoing SSH authentication section in the Fabric OS Administrator's Guide.

Enabling automatic firmware synchronization from active CP to the standby CP Enabling automatic firmware synchronization from active CP to the standby CP Starting with Fabric OS 7.3.0, you can enable automatic firmware synchronization from the active CP blade to the standby CP blade if the following requirements are met. • • • • • The standby CP must be hot-plugged. The firmware version in the active CP should be higher than the firmware version in the standby CP.

Connected switches When you unpack the downloaded firmware, it expands into a directory that is named according to the version of Fabric OS it contains. For example, when you download and unzip v7.3.0.zip, it expands into a directory called v7.3.0. When you issue the firmwareDownload command, there is an automatic search for the correct package file type associated with the switch. Specify only the path up to and including the v7.3.0 directory.

Upgrading firmware for Brocade fixed-port switches CAUTION After you start the process, do not enter any disruptive commands (such as reboot) that interrupt the process. The entire firmware download and commit process takes approximately 17 minutes. If there is a problem, wait for the timeout (30 minutes for network problems) before issuing the firmwareDownload command again. Disrupting the process can render the switch inoperable and require you to seek help from your switch service provider.
Firmware download on a Backbone Firmware download on a Backbone ATTENTION To successfully download firmware, you must have an active Ethernet connection on each CP. You can download firmware to a Backbone without disrupting the overall fabric if the two CP blades are installed and fully synchronized. Use the haShow command to verify that the CPs are synchronized prior to beginning the firmware download process.
Firmware Download Scenarios NOTE By default, the firmwareDownload command automatically upgrades both the active and the standby CPs and all co-CPs on the CP blades in the Brocade Backbones. It automatically upgrades all AP blades in the Brocade Backbones using autoleveling. 1. Verify that the Ethernet interfaces located on CP0 and CP1 are plugged into your network. 2. Verify that the FTP, SFTP, or SSH server is running on the host server and that you have a user ID on that server. 3.
Firmware download from a USB device Network Protocol (1-auto-select, 2-FTP, 3-SCP, 4-SFTP)) [1]: Password: Checking version compatibility... Version compatibility check passed. The following AP blades are installed in the system. Slot Name Versions Traffic Disrupted ----------------------------------------------------------------2 FS8-18 v7.3.0 Encrypted Traffic 8 FX8-24 v7.3.0 GigE This command will upgrade the firmware on both CPs and all AP blade(s) above.
Enabling the USB device Enabling the USB device 1. Log in to the switch using an account assigned to the admin role. 2. Enter the usbStorage -e command. Viewing the USB file system 1. Log in to the switch using an account assigned to the admin role. 2. Enter the usbStorage -l command. BrcdDCXBB:admin> usbstorage -l firmware\ 381MB 2013 v7.3.
Updating the firmware key downloaded, it can be used to validate the firmware to be downloaded next time when you run the firmwareDownload command. The public key file on the switch contains only one public key. It is only able to validate firmware signed using one corresponding private key. If the private key changes in future releases, you need to change the public key on the switch by one of the following methods: • By using the firmwareDownload command.
Power-on firmware checksum test cfgload attributes SelectYes. The following questions are displayed: Enforce secure config Upload/Download: Select yes . Enforce signed firmware download: Select yes. Webtools attributes Press Enter to select default setting; default is no. System Press Enter to select default setting; default is no. Power-on firmware checksum test FIPS requires the checksums of the executables and libraries on the filesystem to be validated before Fabric OS modules are launched.

Testing and restoring firmware on Backbones ATTENTION Downloading firmware to a switch can be disruptive to switch traffic. 7. Connect to the switch, log in as admin, and enter the firmwareShow command to confirm that the primary partition of the switch contains the new firmware. You are now ready to evaluate the new version of firmware.
Testing different firmware versions on Backbones NOTE Brocade recommends that, under normal operating conditions, you maintain the same firmware version on both CPs, and on both partitions of each CP. This organization enables you to evaluate firmware before you commit. As a standard practice, do not run mixed firmware levels on CPs. Testing different firmware versions on Backbones 1. Connect to the Brocade Backbone IP address. 2. Enter the ipAddrShow command and note the address of CP0 and CP1. 3.
Testing and Restoring Firmware c) d) At this point the firmware downloads to the standby CP only and reboots it. The current Backbone session is disconnected. Wait one minute for the standby CP to reboot, and then connect to the Backbone and log in as admin. Enter the firmwareShow command to confirm that both primary partitions have the test drive firmware in place. You are now ready to evaluate the new version of firmware.
Validating a firmware download If an AP blade is present : Blade partitions always contain the same version of the firmware on both partitions. The firmware is stored on the blade’s compact flash card and is always synchronized with the active CP’s firmware. Thus, if you restore the active CP firmware, the blade firmware is automatically downloaded (autoleveled) to become consistent with the new CP firmware (the blade firmware is restored).
