启动顺序：
1. classroom
2. workstation
3. power
4. utility
5. director和overcloud 相关节点机器

启动集群
(undercloud) [stack@director ~]$ rht-overcloud.sh start
关闭集群
(undercloud) [stack@director ~]$ rht-overcloud.sh stop
查看节点状态
(undercloud) [stack@director ~]$ openstack baremetal node list
(undercloud) [stack@director ~]$ openstack baremetal node list -c Name -c 'Power State'

查看状态和启动
(undercloud) [stack@director ~]$ openstack server list -c Name -c Status
(undercloud) [stack@director ~]$ openstack server start compute1
(undercloud) [stack@director ~]$ openstack server list -c Name -c Status
(undercloud) [stack@director ~]$ openstack server start controller0
(undercloud) [stack@director ~]$ openstack server set --state active controller0
(undercloud) [stack@director ~]$ openstack server list -c Name -c Status

如果服务器启动有困难，并且不能响应前面的启动或设置状态命令，则强制重新引导对于清除当前问题有效，如本示例所示。
(undercloud) [stack@director ~]$ openstack server reboot --hard controller0

重置overcloud的要点
Never Need To Be Reset
• classroom
• workstation
• power
• utility
Only Reset Together As A Group
• controller0
• compute0
• compute1
• computehci0
• ceph0
• director

在不重置director的情况下重置overcloud将加载一个新的overcloud，同时该控制器将保留关于刚刚丢弃的前一个overcloud的陈旧信息。
[root@foundation0 ~]# rht-vmctl reset undercloud
[root@foundation0 ~]# rht-vmctl reset overcloud
