Administrator Guide

Before you begin
To perform a graceful shutdown of the Dell Hybrid Cloud System for Microsoft stamp you must follow this sequence:
• The cluster names and IP addresses for the compute cluster, Scale-Out File Server (SOFS), and SQL Server guest cluster
• Host names and IP addresses for the compute cluster, storage cluster, and SQL Server guest cluster
• Infrastructure VM names and IP addresses.
For information about how to collect this information by using Windows PowerShell, see Appendix C: Commands to retrieve cluster names,
host names
, and IP addresses.
You can perform shutdown and startup processes from the Console VM with an account that is a member of the < Prex >-Setup-Admins
security group.
It is recommended that you read this entire section before you shut down the stamp to familiarize yourself with the steps involved.
Unless otherwise noted, for any instruction where you must open a Windows PowerShell session or the command prompt, open these
tools with elevated user rights; that is, started with the Run as Administrator option.
Shutting down the stamp
At a high level, shutdown steps are as listed below. Detailed instructions for each step are in the sections that follow:
1 If the Dell Hybrid Cloud System for Microsoft backup infrastructure is in place, check and stop any running backup jobs.
2 Shut down DPM VMs.
3 Shut down the backup hosts.
4 Shut down tenant VMs.
5 Shut down all infrastructure VMs except for the Console VM.
6 Shut down the compute cluster hosts.
7 Shut down the le serv
er cluster hosts.
8 Optionally, turn o the JBODs. However, this requires physical presence.
9 Optionally, unplug the network switches. This also requires physical presence.
10 Turn o power to the stamp (the power distribution units or PDUs.
Use the following detailed procedures to gracefully shut down the stamp.
Preparing a laptop if iDRACs are connected
If the integrated Dell Remote Access Controllers (iDRACs) are connected in the environment, Dell recommends using a laptop to perform
these t
asks.
To prepare the laptop:
1 Connect the laptop to port 39 or 40 of the switch for the Dell Hybrid Cloud System for Microsoft stamp. This switch is the network
s
witch that you use for management of Dell Hybrid Cloud System for Microsoft infrastructure components through iDRAC
connections.
2 Congure the lap
top 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—or a later version—on this laptop so that you can start the virtual console through the iDRAC interface.
