5. 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 216 6. 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: switch:admin> hashow Local CP (Slot 5, CP0): Active, Warm Recovered Remote CP (Slot 6, CP1): Standby, Healthy HA enabled, Heartbeat Up, HA State synchronized CP blades must be synchronized and running Fabric OS 6.0.0 or later to provide a nondisruptive download. If the two CP blades are not synchronized, enter the haSyncStart command to synchronize them. If the CPs still are not synchronized, contact your switch service provider. 7. Enter the firmwareDownload command. 8. Respond to the prompts as follows: Server Name Enter the name or IP address of the FTP server, or SSH server for SCP, where the firmware or IP Address file is stored; for example, 192.1.2.3. IPv6 and DNS are supported by firmwareDownload in 5.3.0. If DNS is enabled and a server name instead of a server IP address is specified in the command line, firmwareDownload determines whether IPv4 or IPv6 should be used. User name Enter the user name of your account on the server; for example, JaneDoe. File name 6.0.0 or later: Specify the fully qualified path name of the firmware directory, for example, /pub/v6.0.0. Absolute path names may be specified using forward slashes (/). Network protocol Specify the file transfer protocol used to download the firmware from the file server. Valid values are FTP and SCP. The Values are not case-sensitive. If -p is not specified, firmwareDownload will determine the protocol automatically by checking the config.security parameter on the switch. Password Enter a password. This operand can be omitted if firmware is accessible through a local directory, or if no password is required by the FTP server. This operand is required when accessing an SSH server. 9. At the Do you want to continue [y/n] prompt, enter y. The firmware is downloaded to one CP blade at a time, beginning with the standby CP blade. During the process, the active CP blade fails over. After the firmware is downloaded, a firmware commit starts on both CP blades. The entire firmware download and commit process takes approximately 15 minutes. If an AP blade is present: At the point of the failover an autoleveling process is activated. Autoleveling is triggered when the active CP detects a blade that contains a different version of the firmware, regardless of which version is older. Autoleveling downloads firmware to the AP blade, swaps partitions, reboots the blade, and copies the new firmware from the primary partition to the secondary partition. If you have multiple AP blades, they are updated simultaneously; however, the downloads can occur at different rates. Auto-leveling takes place in parallel with the firmware download being performed on the CPs, but does not impact performance. Fibre Channel traffic is not disrupted during auto-leveling, but GbE traffic on AP blades may be affected. Fabric OS 6.2 administrator guide 221
