682 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
You can shut down only one node canister, or you can shut down the entire cluster. When you 
shut down only one node canister, all activities remain active. When you shut down the entire 
cluster, you need to power on locally to start the system.
13.2.1  Shutting down and powering on a complete infrastructure
When you shut down or power on the entire infrastructure (storage, servers, applications), 
follow a particular sequence for both the shutdown and the power-on actions. Next, we 
describe an example sequence of a shutdown, and then a power-on of an infrastructure that 
includes IBM Storwize V7000 system. 
Shutting down
To shut down the infrastructure, complete the following steps:
1. Shut down your servers and all applications.
2. Shut down your IBM Storwize V7000 systems:
a. Shut down the Storwize V7000 by using the GUI or CLI. For more information, see 
4.7.2, “Shutting down the system” on page 124.
b. Power off both switches of the controller enclosure.
c. Power off both switches of all the expansion enclosures.
3. Shut down your SAN switches.
Powering on
To power on your infrastructure, complete the following steps:
1. Power on your SAN switches an d wait until the boot completes.
2. Power on your storage systems by completing the following steps:
a. Power on both power supplies of all the expansion enclosures.
b. Power on both power supplies of the control enclosure.
3. When the storage systems are up, power on your servers and start your applications.
13.3  Configuration backup
You can download and save the configuration backup file by using the IBM Storwize V7000 
graphical user interface (GUI) or command-line interface (CLI). On an ad hoc basis, manually 
perform this procedure because it can save the file directly to your workstation. The 
command-line option requires login to the system and downloading the dumped file by using 
specific Secure Copy Protocol (SCP). The command-line option is a good practice for an 
automated backup of the configuration.
The backup file is updated by the cluster every day. Saving it after any changes to your 
system configuration is also important. It contains configuration data of arrays, pools, 
volumes, and so on. The backup does not contain any data from the volumes.
Important: Generally, perform a daily backup of the Storwize V7000 configuration backup 
file, which is the best approach is to automate this task. Always perform another backup 
before any critical maintenance task, such as an update of the IBM Spectrum Virtualize 
software version.
