CP blades must be synchronized and running Fabric OS 4.2.0 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 HP.
7. Enter the firmwareDownload –s 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
or IP Address the firmware file is stored; for example, 192.1.2.3. IP6 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 IP4 or IP6 should be used.
User name Enter the user name of your account on the server; for example, "JaneDoe".
5.3.0 or later: Specify the fully qualified path name of the firmware
File name
directory, for example, /pub/5.3.0. Absolute path names may be specified
using forward slashes (/).
5.2.0 or earlier: Specify the full path name of the firmware directory,
appended by release.plist; for example, /pub/5.2.0/release.plist.
Note: For 4.x and 5.x switches only, do not attempt to locate the
release.plist file in the top level directory; there is a release.plist file for each
platform, and the correct one is automatically selected.
Network Specify the file transfer protocol used to download the firmware from the file
protocol 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.
