实战:Brocade交换机升级OS

现有2台Brocade VDX 6740,OS版本是4.1.3a. 为解决某个问题,尝试升级到5.0.2.

OS升级包是从Brocade技术支持那获得,话说自己去下载的话好像很麻烦的样子,

反正他们有技术支持,让他们传的话,省时省力。

不多说了,以下是升级操作:


1.查看目前版本,

B6740-1# show version rbridge-id all

2. 备份目前的配置到U盘。

#usb on

B6740-1# copy running-config usb://config.old.vcs

B6740-1# usb off
2015/08/05-07:17:34, [RAS-3004], 2018,, INFO, B6740-Fabric-Chassis, USB storage device disabled.
Rbridge-id: 1
USB storage disabled

B6740-1#


3.把新的OS拷到U盘上, 必须说明一点:brocade交换机识别U盘,是个很诡异的事情,如果不想出乱子,最后还是用Brocade送的U盘,而且不要把U盘的文件夹随便删除。

把OS拷贝到U盘的\firmware下。


4. 通过U盘升级

#usb on

#firmware download usb directory nos5.0.2
Performing system sanity check...
2015/08/05-08:37:03, [LOG-1000], 2565,, INFO, B6740-Fabric-Chassis, Previous message has repeated 1 times.



This command will cause a cold/disruptive reboot and will require that existing telnet, secure telnet or SSH sessions be restarted.

Do you want to continue? [y/n]:

敲下y,等它跑完就可以了。



如果你的环境像我一样有配置VCS的话,那每一台的交换机都需要升级。


升级完的结果:

B6740-1# show version briefrbridge-id all

rbridge-id 1

Slot   Name    Primary/SecondaryVersions                        Status

SW/1   NOS    5.0.2                                             STANDBY

               5.0.2                                              

rbridge-id 2

---------------------------------------------------------------------------

               5.0.2                                              

SW/1   NOS    5.0.2                                             STANDBY

               5.0.2                                              


比较遗憾的是,升级后并没有解决我的问题,烦...
