d When the host is shut down, continue to the next host. Always wait until the current host shuts down before you shut down the
next host. Continue until all compute cluster hosts are shut down.
2 Method 2: Connect through the iDRAC
If the iDRACs are connected, you can use the following method to shut down the compute cluster hosts:
a Using the laptop that is connected to port 39 or 40 of the switch, connect to the IPv4 iDRAC address of a compute cluster host
by using a browser (for example
https://192.168.164.133).
b Expand Overview-Server-Power/Thermal. Click the Power Control tab. Click Graceful Shutdown, and then click Apply.
c Repeat for every compute cluster on the stamp.
Step 7: Shut down the le server cluster hosts
Finally, shut down the le server cluster hosts. You can follow the same procedure as in the previous step, except specify the le server
cluster host names or iDRAC IP addresses. Make sure that you shut down the hosts one at a time.
Step 8: Shut down other hardware devices
At this point, the JBODs are still powered on and are not remotely manageable in terms of power on/o.
Depending on the reason for the stamp shutdown (maintenance versus relocation), you can do either of the following:
• Power them o by switching o the PDUs for the rack, or
• Switch them o individually. Press the on/o switch on the back of the device.
Starting up the stamp
At a high level, the Dell Hybrid Cloud System for Microsoft startup sequence steps are as follows:
1 Power Distribution Units (PDUs)
2 JBODs
3 File server cluster hosts
4 Compute cluster hosts
5 Infrastructure VMs
6 Tenant VMs
7 Backup hosts
8 DPM VMs.
Use the following detailed procedures to gracefully start up the stamp.
Prerequisites
Prepare a laptop if iDRACs are connected
If the iDRACs are connected in the environment, Dell recommends that you use a laptop to perform these tasks.
1 Connect the laptop to port 39 or 40 of the switch of the Dell Hybrid Cloud System for Microsoft stamp. This switch is the network
switch that you use for management of Dell Hybrid Cloud System for Microsoft infrastructure components through iDRAC
connections.
2 Congure the laptop with a static IP address from the iDRAC subnet range. This step enables network communication to the iDRACs
in the Dell Hybrid Cloud System for Microsoft stamp.
3 Install Java version 7 on this laptop so that you can start the virtual console through the iDRAC interface.
Ensure that AD DS services are available
