博科SAN交换机学习笔记之二：配置文件备份与固件升级

配置文件恢复

当需要备份中恢复交换机配置时，可以通过configdownload命令将博科交换机的配置从远程服务器恢复到交换机。博科交换机支持将旧版本的配置文件导入新版本固件的交换机，例如将v6.2.0的配置文件导入v6.3.0固件版本的交换机，或者将v6.4.1 配置文件导入 v7.0.0 版本的交换机。

如果将配置文件导入到不兼容的固件版本交换机，可能导致交换机故障。建议经常保存配置文件，确保备份的配置文件与交换机固件版本相同。

固件v6.1.0及以后的版本，恢复配置文件时不需要disableswitch。某些特殊情况下，恢复配置文件以后会提示你重启交换机。

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.

固件升级

升级固件前，查看一下根分区的磁盘容量，如果使用率超过60%，建议联系Brodecade技术支持处理。

FCSwitch:root> df
