连结7000 ：N7k-Sup2/E微型闪存升级程序
简介
本文描述步骤升级在激活和备用Supervisor的N7K-SUP2/E Bootflash固件永久解决在软件缺陷讨论的固件问题CSCus22805 ：N7K-SUP2/E ：eUSB闪存故障或无法保存配置和CSCuv18883
N77-SUP2E eUSB微型闪存疏忽或无法保存配置。
背景信息
此步骤升级在两个Supervisor的Bootflash固件在连结7000个机箱，当在您的当前软件版本时。 作为替代方案，您可以升级到NX-OS包含CSCus22805的固件修正的软件版本。
另一个选项是使用闪存恢复工具(下载的联机)并且能自动地改正所有单个闪存错误，当存在。这不是永久的修正。用本文突出显示的此步骤永久升级Bootflash固件，以便内置嵌入式闪存设备不再是易受RAID失败。
每个N7K Supervisor 2/2E配备有在RAID1配置，一主要的和一镜像的2个eUSB闪存设备。同时他们为启动镜像、启动配置和不变应用程序数据提供非易变信息库。
什么能发生在几个月内是或几年在使用中，这些设备之一可能从USB总线被断开，造成RAID软件从配置丢弃设备。设备能用1/2设备通常仍然作用。然而，当第二个设备退出阵列时， Bootflash被重登上如只读，含义我们不能保存配置或文件到Bootflash，或者请允许待机同步到在重新加载的事件的激活。
没有在运行在一双重闪存故障状态的系统的操作影响，然而受影响的Supervisor的重新加载是需要的从此状态恢复。此外，在断电情形下，对运行的配置的任何变化不会反射在启动上，并且丢失。
6.2维护版的要汇总， 6.2(20)有被提及的所有3个软件缺陷的一个修正在上述注意。
先决条件

本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- Cisco连结7000系列交换机，版本6.2(10)
- N7K SUP2
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
升级 程序
1. 控制到激活和备用Supervisor。
2. 复制在激活和备用Supervisor上Bootflash的NX-OS 7.2(1)D1(1)。
3. 设置在待机的kickstart和系统引导变量为NX-OS 7.2(1)D1(1)。
N7K-1(config)# boot kickstart bootflash:n7000-s2-kickstart.7.2.1.D1.1.bin sup-2
Performing image verification and compatibility check, please wait....
Note: system and kickstart bootvars are pointing to incompatible images
N7K-1(config)# boot system bootflash:n7000-s2-dk9.7.2.1.D1.1.bin sup-2
Performing image verification and compatibility check, please wait....
4. 保存所有VDCs的配置并且确认在下一次重新加载的引导变量设置为在备用Supervisor的NX-OS 7.2(1)D1(1)。

5. 重新加载备用Supervisor。
N7K-1# reload module 2

6. 备用Supervisor启动7.2(1)D1(1) kickstart镜像并且升级Bootflash固件。一旦备用Supervisor尝试启动7.2(1)D1(1)系统镜像，将检测版本不匹配并且重新加载与从激活的Supervisor的前一个镜像。

9. 重新加载备用Supervisor。
N7K-1# reload module 1 This command will reboot standby supervisor module. (y/n)? [n] y
10. 备用Supervisor将启动7.2(1)D1(1) kickstart镜像并且升级Bootflash固件。一旦备用Supervisor尝试启动7.2(1)D1(1)系统镜像将检测版本不匹配并且重新加载与从激活的Supervisor的前一个镜像。

12. 一旦完成在vPC复杂的一个成员的上述步骤，您将要验证服务和继续执行在vPC对的第二个成员的同一个步骤。
警告
步骤要求非中断的Supervisor切换。然而，在更改窗口时执行这些步骤，为了避免所有惊奇是可行的。
