System stops booting after the ok prompt is displayed.
|
At the ok prompt type: boot
If the system does not boot, contact your system administrator or a Sun Service Support Center.
|
CD or DVD does not eject from the media tray when you press the Eject button.
|
User-Level Procedures
- Move the mouse or press any key on the keyboard. The drive might be in low-power mode.
- Attempt to eject the CD or DVD using the Eject button on the media drive.
- In a terminal window type: eject cdrom
- If Step 3 does not work, verify that the CD or DVD is not mounted. In a terminal window, type: df | grep cdrom
If the CD or DVD is mounted, text similar to this example will be displayed:
/cdrom/wzi-2230 (/vol/dev/dsk/c0t2d0/wzi-2230): 0 blocks 0 files
- Unmount the CD or DVD by typing: umount and the command output shown in parentheses above. In the example above, the mount point is wzi-2230 and you would type: umount /vol/dev/dsk/c0t2d0/wzi-2230
- Type the command: eject cdrom
Alternate Procedure for Media CDs or DVDs
- Right-click the mouse and select Workspace MenuFoldersOpen CDROM.
A File Manager window should open.
- Select FileEject.
- If the CD or DVD does not eject, use a terminal window to exit the CD or DVD directory by typing: cd
- Try again to eject the CD or DVD from the File Manager window.
If you need further assistance, contact your system administrator or a Sun Service Support Center.
System Administrator Emergency Procedures for All CDs or DVDs
As superuser, stop the vold daemon:
- Open a terminal window.
- As superuser, type: /etc/init.d/volmgt stop
- Press the Eject button on the media player.
Note: To mount another CD or DVD, you need to start vold by typing:
/etc/init.d/volmgt start
If the CD or DVD has not ejected using Step 3 above, complete these steps:
- Bring the system to the ok prompt.
- Press the Eject button.
If the CD or DVD still does not eject using the two processes above, there might be a cable problem or other hardware problem. Call a Sun Service Support Center for further assistance.

No video displays on the monitor screen.
|
- Is the monitor cable attached to the graphics accelerator?
- Does the monitor work when connected to another system?
- If you have another monitor, does it work when connected to the original system?
- Verify that OpenBoot PROM defaults are set properly:
a. Press and hold the Power button for 4 seconds to power off the system.
b. Wait 4 seconds and power on the system.
c. As soon as the Power button blinks, quickly press the Power button twice. The ok prompt is displayed and the system enters a safe NVRAM mode.
d. Verify these OpenBoot PROM parameters: output-device is set to screen and input-device is set to keyboard.
e. If the ok prompt does not display, or if changing the output-device setting does not help, contact a Sun Service Support Center.

Workstation does not power on when the front panel Power button is pressed.
|
Keep notes on the following situations in case you need to call service:
- Is the Power button LED illuminated on the front of the system?
(Ensure that the power cord is connected to the system and to a grounded power receptacle.)
- Does the wall outlet have power? Test by plugging in another device.
- Does the system beep when the system is powered on? (Ensure that the keyboard is plugged in.)
- Test with another keyboard that you know is functional. Does the system beep when you connect the keyboard and power on the system?
- Does the monitor sync within 5 minutes after power on? (The green LED on the monitor stops flashing and remains illuminated.)
Note: If the monitor syncs but does not display an ok prompt or a login window, the system might not be passing POST. Call a Sun Service Support Center.
If the system passes POST and displays the ok prompt but does not boot Solaris,
type: boot
|
Keyboard or mouse does not respond to actions.
|
- Verify that the mouse and keyboard cables are connected to the on-board USB 1.1 connectors on the workstation. (Do not connect the mouse and keyboard to the USB connectors on the IEEE 1394 and USB 2.x card.)
- Verify that the workstation is powered on and the front Power button LED is illuminated.
|
Workstation appears to be in low-power mode, but the Power button LED does not blink.
|
The power-indicator LED only blinks when all workstation components are in low-power mode. A tape drive might be connected to your workstation. Because tape drives do not enter low-power mode, the power-indicator LED does not blink.
|
Hung application. Application won't respond.
|
Procedure 1: Using the Host Workstation
- From the CDE toolbar, select ToolsProcess.
- In the Process Manager window, select Find Process.
- Select the process that is hung. The name of the application or process is in the Command column.
- From the Process Manager menu, select ProcessKill Process.
Note: You may be able to log in from another workstation and use these same GUI tools to save and close, or kill applications.
Procedure 2: Using a Terminal Window From Your Own Workstation
- To determine the ID number of the hung process, type: ps -ef | grep process name
Note: First kill the last application you used when the system hung and, if necessary, kill the next most recent applications that you used.
- To stop the process, type: kill -9 process ID
Procedure 3: Using Remote Login or Telnet
- From another workstation, use a terminal window and type either:
rlogin hostname
or type: telnet hostname
- Type your login ID and password.
- From the terminal window, type: ps -ef | grep process name
- Start killing processes. Type the name of the last application you were using when the system froze.
Type: kill -9 process ID
After killing the processes for the last-used application, look at your system to see if it is usable. If not, continue to kill processes until the system is usable or until you can shut it down and restart it.
Caution: Be sure to log off from the remote system. Another user might be able to access your system if you do not exit the terminal window.
- On the second workstation, type exit and close the terminal window.
|
During the boot procedure, the system displays a network error message.
|
Use this procedure if the system displays these error messages:
Warning: timed out waiting for NIS to come up
:Timeout waiting for ARP/RARP packet
- From a remote system, ping the system with this command: ping hostname
- Verify with your system administrator that the network is operational.
- Is the Ethernet cable connected between the workstation and the wall outlet or router?
- Try connecting another Ethernet cable. Does the new cable work?
- If cable changes do not help, bring the system to the ok prompt and verify the OpenBoot PROM settings. Most systems should be set to diag-switch? = false and boot-device set to disk net. For more information on OpenBoot PROM settings, see the Sun Blade 1500 Service, Diagnostics, and Troubleshooting Manual (817-5127), or contact a Sun Service Support Center.
|
Hung or frozen workstation: No response from mouse or keyboard or any application.
|
- Try to access your system from a different workstation on the network.
- From a terminal window type: ping hostname
- If no response, remotely log in from another system using telnet or rlogin, and ping the system again.
- Attempt to kill processes until the system responds. (See the procedures for "Hung Application" in this table.)
If the above procedures do not work:
Caution: Only experienced system administrators should use a "Stop" command. Using any "Stop" command might cause loss of core dumps, which makes it difficult to diagnose system problems.
- Press Stop-A. If the system responds, the system displays the ok prompt.
- Try to force a core file dump. At the ok prompt, type this command: sync
Note: The default location for a core file deposit is: /var/crash/hostname
The Sun Service Support Center might request the core file for root cause analysis.
If the above procedures do not work:
- Press the Power button to power off the system.
- Wait 20 to 30 seconds and power on the system.
Note: When you power on the system again, you might need to run fsck to repair damaged links. If the system still does not function properly, contact Sun Service Support.

System Beeps
|
Continuous beeping: inspect for a stuck key on the keyboard or reconnect the keyboard. Three or four beeps followed by system power-off may indicate memory, CPU, or motherboard problems. See Chapter 3 of the Sun Blade 1500 Service, Diagnostics, and Troubleshooting Manual (817-5127) or call a Sun Service Support Center.
