Backing up the configuration file of the switch is important. You need to back up the configuration file periodically and be familiar with the process of restoring the configuration file. If a new Fibre Channel switch is purchased,
Backing Up Configuration Files
The configuration file is backed up to a remote server each time the FC switch is configured. The SCP, FTP, and SFTP protocols are supported. You can run the configupload command to save the configuration of the Brocade switch in text format to the local host.
FCSwitch:root> configupload
Protocol (scp, ftp, sftp, local) [ftp]: ftp
Server Name or IP Address [host]: ftp.liaojl.com
User Name [user]: liaojl
Path/Filename [<home dir>/config.txt]: FCSwitch/FCSwitch-all.txt
Section (all|chassis|switch [all]): all
Password:
configUpload complete: All selected config parameters are uploaded
The following information is not saved during the backup process:
dnsConfig information
Passwords
If no FTP or SFTP server is available, you can use the SCP to copy the file to a Linux server.
Restoring Configuration Files
To restore the configuration of the Brocade switch from the remote server to the switch, run the configdownload command. You can import the configuration file of an earlier version to a switch with a new firmware version. For example, you can import the configuration file of v6.2.0 to a switch with a firmware version of v6.3.0 or import the configuration file of v6.4.1 to a switch with a firmware version of v7.0.0.
Importing a configuration file to a switch with an incompatible firmware version may cause the switch to fail. You are advised to save the configuration file frequently to ensure that the version of the backup configuration file is the same as that of the switch firmware.
For firmware v6.1.0 and later versions, disable switch is not required when you restore the configuration file. In some special cases, after the configuration file is restored, the system prompts you to restart the switch.
FCSwitch:root> configdownload

*** CAUTION ***
This command is used to download a backed-up configuration
for a specific switch. If using a file from a different
switch, this file's configuration settings will override
any current switch settings. Downloading a configuration
file, which was uploaded from a different type of switch,
may cause this switch to fail. A switch reboot might be
required for some parameter changes to take effect.
configDownload operation may take several minutes
to complete for large files.

Firmware upgrade
Before upgrading the firmware, check the disk space of the root partition. If the disk space usage exceeds 60%, contact Brocade technical support.
