Connected Switches; Finding The Switch Firmware Version - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

NOTE: IPv6 and DNS are supported by firmwareDownload in 6.0.0 or later. 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.
To be able to mention the FTP server by name, you must enter at least one DNS server using the
dnsConfig command.
3. Perform a configUpload prior to the firmwareDownload. Save the config file on your FTP or SSH
server or USB memory device on supported platforms.
4. Optional: For additional support, connect the switch to a computer with a serial console cable. Ensure
that all serial consoles (both CPs for directors) and any open network connection sessions, such as
Telnet, are logged and included with any trouble reports.
5. Connect to the switch and log in to the switch as admin. Enter the supportSave command to retrieve
all current core files prior to executing the firmware download. This helps to troubleshoot the firmware
download process if a problem is encountered.
If you are upgrading a director, log in to both the active and standby CPs and enter the supportSave
command on each CP.
NOTE: If you do not know the CP address, use the ipAddrShow command to view a list of all CP IP
addresses associated with the switch.
6. Optional: Enter the errClear command to erase all existing messages in addition to internal
messages.
