Troubleshooting

C

This appendix provides troubleshooting procedures if the power key does not suspend your system or if you need to recover from a hung system.

Power Key Does Not Suspend the System

If pressing the power key does not suspend your system, use a shell to verify that the key processing daemon is present.

* Type


  % ps -eaf | grep speckeysd

If the resulting message does not list /usr/openwin/bin/speckeysd, you should start the key processing daemon by entering:


  % /usr/openwin/bin/speckeysd

What to Do If a Device Suspend Fails

If a device fails to suspend, an alert pop-up window is displayed, as shown in Figure C-1. Additional information about the failure is also displayed in the console window.

Figure C-1

Select Cancel.
Take corrective action before retrying suspend again. If you have not already saved your work, do so now.
Check for more information in the Console window in the Workspace.
This error can be caused by an unsupported device or a device performing non-resumable activity. If your system contains devices in addition to the default configuration, then these devices may not support the Suspend feature. In this case, either unload the device driver (contact your system administrator) and try suspend again, or obtain a device driver that supports suspend from your manufacturer. If the device specified by the console message is performing a non-resumable activity, stop the activity and try suspend again.
Try Suspend again.

If Suspend succeeds, the system will save your activities and the system will power off.
If Suspend does not succeed, the alert pop-up window is displayed again.

Caution - Save your work if you have not already done so.

Select Power Off.
The error persists and therefore suspend is not possible. This step shuts down the system properly without causing file system damage. Your data will not be saved unless you have done so manually. When you power on again, your system automatically reboots.
If you select Power Off and it fails, an alert pop-up window is displayed with information about the power-off failure, as shown in Figure C-2.

Figure C-2

Select Continue.
Your system does not support software power off. This could be due to a non-type 5 keyboard or an outdated system PROM. If you have a type 5 keyboard installed then contact your system provider for a system PROM upgrade.
Save your work if you have not already done so.
Halt the Operating System.
Power off by pressing the power switch on the back panel of the system to the off (0) position.

What to Do If a Process Fails to Suspend

If a process cannot be properly suspended, an alert pop-up window is displayed, as shown in Figure C-3. Additional information about the failure is also displayed in the console window,

Figure C-3

Select Cancel.
Retry suspend again. If you have not already saved your work, do so now.
Check for more information in the Console window in the Workspace.
If it is a real time process or if it is performing certain special network operations, a process may refuse to suspend gracefully. In most cases, this is only a temporary condition and can be corrected by trying suspend again. If this condition persists, stop the offending process as specified in the console and retry suspend again.
Try Suspend again.

If Suspend succeeds, the system will save your activities and the system will power off.
If Suspend does not succeed, the alert pop-up window is displayed again.

Caution - Save your work if you have not already done so.

Select Power Off.
Your data will not be saved unless you have done so manually. When you power on again, your system automatically reboots.

What to Do If More Disk Space Is Needed

If there is not enough disk space to store the suspend state file, an alert pop-up window is displayed, an alert pop-up window is displayed, as shown in Figure C-4. Additional information about the failure is also displayed in the console window.

Figure C-4

Select Cancel.
Take corrective action before retrying suspend again. If you have not already saved your work, do so now.
Check for more information in the Console window in the Workspace.
You must have about 10 MBytes of space in your root partition. Clean up the root partition and try suspend again. Contact your system administrator for assistance if necessary.
Try Suspend again.

If Suspend succeeds, the system will save your activities and the system will power off.
If Suspend does not succeed, the alert pop-up window is displayed again.

Caution - Save your work if you have not already done so.

Select Power Off.
Your data will not be saved unless you have done so manually. When you power on again, your system automatically reboots.

What to Do If Abnormal Conditions Occur

If a rare error has been detected, an alert pop-up window is displayed, as shown in Figure C-5. Additional information about the failure is also displayed in the console window.

Figure C-5

Select Cancel.
Take corrective action before retrying suspend again. If you have not already saved your work, do so now.
Check for more information in the Console window in the Workspace.
You may be able to take further corrective action by checking the console error messages.
Try Suspend again.

If Suspend succeeds, the system will save your activities and the system will power off.
If Suspend does not succeed, the alert pop-up window is displayed again.

Caution - Save your work if you have not already done so.

Select Power Off.

Your data will not be saved unless you have done so manually. When you power on again, your system automatically reboots.
