 How to Discover Xserve on Your Network
How to Discover Xserve on 
Your Network
Follow the steps outlined below to remotely administer Xserve.
Note: This procedure veriÞes basic connectivity to Xserve, which can help isolate 
hardware versus software issues. 
Preliminary Steps
Make sure that you are doing these steps on an Admin computer with Mac OS X 10.1.5 
Server or Mac OS X 10.1.5 remote admin utilities. You must be logged in to that computer 
with an Admin account. Also, make sure that the server you want to remotely discover is 
started up from the Installer CD. 
Procedure
Option A 
If you already know your Xserves IP address you can quickly verify network connectivity 
by using the following command from a remote admin system using the Terminal 
application: 
ping 17.XXX.XXX.XXX (the X characters represent numerical IP addresses) 
Or
ping  
Your domain extension will resemble something like: .com, .edu, .org 
Option B 
If you wish to automatically discover your Xserve using the Server Assistant, follow these 
steps:
1. Open Server Assistant from a remote admin computer. 
2. Select the Install Mac OS X Server Software option. The Remote installation 
screen appears. All Xserve computers on the same TCP/IP subnet appear in a list 
format. 
3. Select the appropriate Xserve.

 How to Discover Xserve on Your Network Note: To continue, the Þrst 8 characters of the Xserve serial number are required to 
authenticate. The password is case-sensitive. If you encounter difÞculty using this 
password please see technical document 61644: Xserve: Initial Password Is Case 
Sensitive. 
Option C 
As an alternative to using Server Assistant, the following procedure may be performed 
using the Terminal application.
1. Open the Terminal application on the Admin computer. 
2. Type: cd/System/Library/ServerSetup 
3. Press Return. 
4. Type: ./sa_srchr 224.0.0.1 
5. Press Return. 
6. Verify that Xserve shows its correct IP address, hardware (MAC) address, and DNS 
name (if applicable).

 How to Check for Local Hard Drive Issues
How to Check for Local Hard 
Drive Issues
Follow the steps outlined below if you suspect issues with Xserves hard disk, and you 
have physical access to the server.
Preliminary Steps
In order to follow these steps, you must have physical access to Xserve. You cannot 
perform this procedure remotely. A keyboard and monitor must be connected to the server 
before you begin. If you wish to check the startup disk (or volume), you must start up 
Xserve from its Installation CD Þrst, then open Disk Utility from the Þrst Installation screen.
Procedure
1. Log in to Xserve using the connected keyboard and monitor.
2. Open Disk First Aid, which is located in /Applications/Utilities.
3. Select the volume you wish to examine.
 Note: You cannot select the startup volume unless you started up the server from 
the Installation CD.
4. Click Verify to check the disk.
5.  If there were any issues found by Disk First Aid, answer y to any prompts presented.
6.  Repeat steps 4 and 5 until no issues are reported. If Disk First Aid reports the same 
error(s) after repeating the process, you should reformat the hard disk.
Warning: Reformatting or reinitializing the hard disk erases all information stored on it. 
Make sure you have a backup of all Þles you may have created and any preinstalled 
software that came with Xserve.

 How to Remotely Check for Hard Drive Issues
How to Remotely Check for 
Hard Drive Issues
Follow the steps outlined below if you suspect issues with Xserves hard disk, and you do 
not have physical access to the server.
Preliminary Steps
You must have the servers IP address and Admin (or root) password before performing

6. If fsck Þnds any issues, type y to continue.
7. Repeat steps 4 through 6 until fsck Þnds no errors. If fsck reports the same error(s) 
after repeating the process, you should reformat the hard disk.
Warning: Reformatting or reinitializing the hard disk erases all information stored on it. 
Make sure you have a backup of all Þles you may have created and any preinstalled 
software that came with Xserve

 How to Verify Xserve Is Accepting Connections
How to Verify Xserve Is 
Accepting Connections
There are several methods for determining if Xserve has successfully started up and is 
providing basic services. Using a terminal connection to accomplish this task provides the 
most ßexibility. 
Note: You will not be able to perform this procedure if the Xserve is not fully started up. 
Preliminary Steps
You must have the IP address and an Admin (or root) password of the server you wish to 
start up before performing this procedure.
Procedure
1. At the Admin computer, type the following command:
 ssh @ 
2. You should be presented with a password prompt. At this prompt, type the admin 
password. The Xserves default password is the Þrst 8 characters of the Xserves 
serial number, and is case sensitive. 
3. The following should appear if you have logged in correctly:
Welcome To Darwin!
:~] admin% 
4. To determine if any additional drives are available to the Þle system, at the command 
prompt type: df 
5. To verify more information about the Xserves volumes, including which volume the 
Xserve was actually started up from, open Apple System ProÞler from the Terminal 
application by typing: AppleSystemProfiler | grep boot
You may also run Apple System ProÞler with no options for a complete report of the 
Xserve system conÞguration information.
