VCSA备份作业报错，无法连接到FTP

1.首先确保FTP可正常连接

2.在FTP正常的前提下，如果在VCSA备份配置界面提示无法连接到FTP，则需要重启Appliance Management Service

3.SSH连接故障VCSA

4.重启服务一般就可以恢复正常，如果无法解决请联系vmware

输入shell：
Command> shell
Shell access is granted to root

输入命令查看所有vmware服务：
root@vcsa01 [ ~ ]# service-control --status
Stopped:
 vmcam vmware-imagebuilder vmware-mbcs vmware-netdumper vmware-rbd-watchdog vmware-vcha vsan-dps
Running:

重启Running中的applmgmt,这个服务就是Appliance Management Service：
root@vcsa01 [ ~ ]# service-control --restart applmgmt
Successfully restarted service applmgmt
