Cisco Nexus 3524 boot fail into loader mode

1 背景

东京电信网络中断故障处理

Sw07 and SW08 is cisco Nexus 3524

N3K-C3548P-10GX-SUP

报业务中断，查询得知凌晨机房断电过，加电后网络仍无法。检查发现汇聚主交换机

SW07无法登录，而备汇聚SW08的所有VPC端口down，手工将端口leave group and

add again , vpc is UP.

Sw07因重启找不到启动文件而进入loader>，we just boot it and set the boot

variable and save config to startup-config

Nexus 3524重启找不到IOS是因为配置文件中缺少指定IOS的配置。

2 处理过程
