Firmware download on an enterprise-class platform 9 6. The new standby CP blade (the active CP blade before the failover) downloads firmware. 7. The new standby CP blade reboots and comes up with the new Fabric OS. 8. The new active CP blade synchronizes its state with the new standby CP blade. 9. The firmwareCommit command runs automatically on both CP blades. CAUTION After you start the process, do not enter any disruptive commands (such as reboot) that will interrupt the process. The entire firmware download and commit process takes approximately 17 minutes. If there is a problem, wait for the time-out (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. Do not disconnect the switch from power during the process because the switch could become inoperable when rebooted. Upgrading firmware on enterprise-class platforms (including blades) There is only one chassis management IP address for the Brocade 48000 and the Brocade DCX and DCX-4s platforms. NOTE By default, the firmwareDownload command automatically upgrades both the active and standby CP on the Brocade 48000 director. It also automatically upgrades both the active and the standby CP and all co-CPs on the CP blades in the Brocade DCX and DCX-4S Backbones. It automatically upgrades all AP blades in the Brocade 48000, the Brocade DCX and DCX-4S platforms using auto-leveling. 1. Verify that the Ethernet interfaces located on CP0 and CP1 are plugged into your network. 2. Verify that the FTP or SSH server is running on the host server and that you have a user ID on that server. 3. Obtain the firmware file from the Brocade Web site at http://www.brocade.com and store the file on the FTP or SSH server. 4. Unpack the compressed files preserving directory structures. The firmware is in the form of RPM packages with names defined in a .plist file. The .plist file contains specific firmware information and the names of packages of the firmware to be downloaded. 5. Connect to the chassis IP management interface or active CP and log in as admin. 6. Use the firmwareShow command to check the current firmware version on connected switches. Upgrade the firmware, if necessary, before proceeding with upgrading this switch. See "Connected switches" on page 193 7. Enter the haShow command to confirm that the two CP blades are synchronized. In the following example, the active CP blade is CP0 and the standby CP blade is CP1: Fabric OS Administrator's Guide 197 53-1001763-01
