MDS9000 VSAN起不来

刀箱交换机通过EXT0与MDS9124做级联，EXT0的状态不对，而且重启VSAN也起不来，大家帮忙给看看什么原因。谢谢！！

vsan起不来，核实一下几点：
1.vsan中是否没有任何接口？进一步检查这些接口是否全部是down的状态，如果是down状态则vsan起不来。类似于网络交换机中的vlan的概念，如果vlan 中没有任何接口，vlanif是起不来的。
2.做级联的时候，如果交换机1已经激活了某个zoneset，zoneset包含该zone。如果是的话，您要么新建一个zone，从新划分zone，覆盖掉现有的zone。如果有业务请慎重操作！！！！

Isolation due to zone merge failure 这个告警很明显就是在做级联的时候（级联会有一个动作是区域合并，sw1和sw2上的同一个zone进行合并）出现的告警。由此判断，您做级联的时候，交换机中一定已经有zone在使用了。
Zoning modes does not match Rec 该告警就是您两台机的zone模式不匹配，如果做级联，建议两台都开启zone mode enhanced vsan xxx，用于将zoneset信息同步给其他交换机，也是级联的目的。
抛砖引玉，可以参考一下！
