service provider.

Serial port snoop
You can disable or enable serial port snoop on a serial service port. When enabled, data
received on the selected serial port is examined, or
snooped, as it arrives. You can also
specify the snoop string, a particular sequence of bytes that resets the service processor if
detected. In this manner the serial port S1 serves as a “catch-all” reset device for service
personnel.
This function is not available if your system is managed by an HMC. If your system is
managed by an HMC, you will see a panel as shown in Figure 10-15.

System dump
Use this procedure only under the direction of your service provider. You can initiate a system
dump in order to capture overall system information, system processor state, hardware scan
rings, caches, and other information. This information can be used to resolve a hardware or
server firmware problem. A system dump may also be automatically initiated after a system
malfunction, such as a checkstop or hang. It is typically 34 MB.
