Copy Data and Reinstall System Software Remotely

If you have information on the server that you need to preserve, you need to copy the

information to another disk or partition, then copy it back to the server when you’re

ﬁnished. You can use the ditto command to do this.

1 Turn the server off.

2 Press and hold the system identiﬁer button while you press the power button.

3 Continue to hold the system identiﬁer button until the system identiﬁer light flashes and the

CD tray opens.

4 Release the system identiﬁer button and insert the Mac OS X Server CD in the tray.

5 Close the tray. The server starts up from the CD.

6 Open the Terminal application on your admin computer and use SSH to log in to the

target server.

7 Use the ditto command to copy the data from the corrupted startup disk drive or partition to

another disk drive, partition, or FireWire device. (See “Copying Data Between Remote

Servers” on page 78.)

8 Use Server Assistant or the Installer Tool to reinstall the system software on the startup hard

disk or partition. The server restarts at the end of the installation.

9 Run Server Assistant to set up the server again. The Mac OS X Server Information Worksheet

that you ﬁlled out when you ﬁrst set up the server should have all the necessary information.

10 Copy the data back onto the server using the ditto command.

For more information about the Installer Tool, see Chapter 7, “Using Software Installation

Tools and Applications.”

Resetting the Administrator Password

You may want to set a new administrator password if you think the password is no longer

secure, or if you’ve forgotten what it is. You can do this by running Server Assistant again.

Note: If you’ve forgotten the root password, you can’t run Server Assistant remotely. You

need to know the root password to log in.

Rerun Server Assistant Locally

Follow the instructions in the Xserve User’s Guide for connecting a monitor and keyboard to

the server.

2 Log in to the server as the root administrator.
