Flexpod的开关机顺序

Flexpod = Cisco UCS + Cisco Nexus + Netapp （中文名叫做“融合基础架构”）

之前没有接触过这套系统，不太明白怎么个开关机的顺序，借公司停电的机会实际演练了一番：

Power-Off:

1.            Shutdown virtual machines in vCenter

2.            Shutdown hypervisor hosts in vCenter

3.            Go into UCS Manager, then click ‘Shutdown Servers’ to power off each blade

4.            SSH into each Netapp controller, run 'cifs session *' & 'cifs terminate -t 0' to close the CIFS connection

5.            Run 'cf status' & 'cf disable' to disable cluster

6.            Run ‘halt -f -t 0’ to shutdown the controller graceful

7.            Physical power off the storage controller

8.            Physical power off all of the disk shelves

9.            Unplug power cable from Fabric Interconnects

Power-On:

1.            Plug power cable to Fabric Interconnect, wait for minutes

2.            Physical power on all of the disk shelves, wait for minutes

3.            Physical power on the storage controller, wait for minutes

4.            Run 'cf enable' & 'cf status' to enable cluster

5.            Go into UCS Manager, then click ‘Boot Servers’ to turn on each blade

6.            Power on virtual machines in vCenter
