Powering Down the Servers

Before powering down a server, stop the services running on it, as described in "Shutting Down Recovery Appliance".

To shut down a compute server or a storage server:

Log in to the server as root.
Stop the operating system:
```
# shutdown -h -y now
```
Or restart the operating system:
```
# shutdown -r -y now
```

Example 13-1 Powering Off Recovery Appliance Using the dcli Utility

Stop Oracle Clusterware on all compute servers:

# GRID_HOME/grid/bin/crsctl stop cluster -all

Shut down the other compute server in the rack:
```
# dcli -l root -g ra-adm02 shutdown -h -y now
```
In the preceding command, ra01adm02 is the name of the second compute server.
Shut down all storage servers:
```
# dcli -l root -g cell_group shutdown -h -y now
```
In the preceding command, cell_group is a file that lists all storage servers.
Shut down the local compute server:
```
shutdown -h -y now
```
Power off the rack.

Use the dcli utility to run the shutdown command on multiple servers simultaneously. Do not run dcli from a server that will be powered off by the command.

The following example shuts down a group of storage servers listed in a file named cell_group:

# dcli -l root -g cell_group shutdown -h -y now

Example 13-1 shows the power off procedure for the rack when using the dcli utility to shut down multiple servers simultaneously. The commands run from a compute server.
