The following table describes the three modes:
Mode | Description | Automatically enters mode if | |
Host | The computer searches for | You run Server Diagnostics | |
| servers that are on the same | Mac OS X and: | |
| subnet and start Server | ÂÂ | The computer isn’t a Mac |
| Diagnostics in remote mode. | ||
|
| Pro with Mac OS X Server | |
| When one is found, the host |
| |
|

| computer controls Server |
| |
| ÂÂ | You’re not logged in as root | |
| Diagnostics on the client server. | ||
|
|
| |
|
|
| |
Client | The server can be controlled by | You’re running Server | |
| a host computer. | Diagnostics EFI and a host | |
|
| computer is on the same subnet | |
|
| or is directly connected. | |
|
|
| |
Local | The server runs all tests locally. | You’re running Server | |
|
| Diagnostics EFI and a host | |
|
| computer isn’t on the same | |
|
| subnet and isn’t directly | |
|
| connected. | |
|

If you’re logged in as root on the server and you run Server Diagnostics Mac OS X, you can choose which mode to enter.
Remotely Testing a Client Server
To test a client server, you first start up Server Diagnostics on the host computer, set it to connect to the client server, start up the Server Diagnostics on the client server and then set the client server to be a client of the host computer.
The host computer must run Server Diagnostics Mac OS X. The client server can run Server Diagnostics Mac OS X or Server Diagnostics EFI. The available tests are based on which Server Diagnostics the client server is running.
When you start up Server Diagnostics EFI, the server looks for a host computer. If it finds a host computer, the server enters client mode. If it doesn’t find a host computer, the server enters local mode.
When you start up Server Diagnostics Mac OS X, the server becomes a host computer if either of the following are true:
ÂÂ You logged in to Mac OS X with an account that isn’t root.
ÂÂ You’re running Server Diagnostics Mac OS X on a computer that isn’t a Mac Pro with Mac OS X Server installed.
If Server Diagnostics Mac OS X doesn’t automatically become a host computer, it asks if it should connect to a client server, be a client of a host computer, or run tests locally.
