1.SSH連接到集群IP递宅，查看FI的主備狀態(tài)
FI-A# show cluster state
A: UP, PRIMARY
B: UP, SUBORDINATE
可以看到B為備修械。
2.從A登陸到B刨沦，然后重啟

HA NOT READY
Peer Fabric Interconnect is down
FI-B# show cluster state
B: UP, PRIMARY
A: UP, SUBORDINATE
HA READY
4.切換B為主,此時(shí)會(huì)斷開連接害驹，重新登陸集群，查看FI狀態(tài)B為主文捶，A為備
FI-A(local-mgmt)# cluster lead b

FI-B# connect local-mgmt a
FI-A(local-mgmt)# reboot
Before rebooting, please take a configuration backup.
Do you still want to reboot? (yes/no):yes
6.查看FI狀態(tài),切換A為主
