Recovering From a Hung System

If your system does not respond to the mouse or keyboard, perform the following steps:

1. If your system is on a network, wait a few minutes before taking any action.

   A slow response may be due to network problems or delays. Check with your network administrator. If the response is not due to the network, go to the next step.

2. Press Stop-a.

   Hold both keys down at the same time. Pressing Stop-a (or Break) puts the system into the monitor command mode (indicated by the ok prompt).

   Note -

   If you use a Wyse WY-50, DEC VT100, or compatible terminal as the console with your SPARCstation Voyager system unit, press Break instead of Stop-a.

3. Type sync.

   Your file system will be saved.

   ok sync

4. When Stop-a (or Break) is not effective, turn the power off using the power switch on the back panel of the system.

   See Figure 2-3. The system power will turn off without the Suspend sequence. When you turn the system on again, the boot sequence will begin. Your work will not be saved.
