Apple Server Diagnostics - Manual (Page 30)

Mode Description Automatically enters mode if
Host The computer searches for
servers that are on the same
subnet and start Server
Diagnostics in remote mode.
When one is found, the host
computer controls Server
Diagnostics on the client server. You run Server Diagnostics
Mac OS X and either:
 The computer isn’t an Intel-
based Xserve or a Mac
mini with Mac OS X Server
installed
 You’re not logged in as root
Client The server can be controlled by
a host computer. You’re running Server
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 then you run Server Diagnostics
Mac OS X, you can choose which mode to enter.
Remotely Testing a Client Server
If you want to test a client server, you must first start up Server Diagnostics on the
host computer, set it to connect to the client server, and then start up the Server
Diagnostics on the client server and set it 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 first 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 automatically becomes
a host computer if either of the following are true:
You logged in to Mac OS X with an account that isn’t root. Â
You’re running Server Diagnostics Mac OS X on a computer that isn’t an Intel-based Â
Xserve or a Mac mini 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.
