Table 7. High-Level SP symptoms
| Symptoms | Condition | Action |
|---|---|---|
|
controllerResponds indicator on the Frame Notebook in the SP Hardware
Perspective is red, SPdaemon.log reports this variable as 0,
or the Frame Notebook in the SP Hardware Perspective displays blank
nodes.
The hmmon -GQv controllerResponds frame:slot
command shows: Frame responding to polls FALSE.

Frame supervisor failure
| Go to Diagnosing System Monitor problems |
| You get error messages when you start the switch or applications that use the switch fail or hang. | Switch Failure | For the SP Switch, see Diagnosing SP Switch problems.
For the SP Switch2, see Diagnosing SP Switch2 problems. |
| switchResponds indicator on the Nodes Noteboook in the SP Hardware Perspective is red, meaning that the node is not currently available to the switch network. When the indicator is yellow, the node is available to, but not part of, the network. |
Switch or switch adapter problems
| For the SP Switch, see Diagnosing SP Switch problems.
For the SP Switch2, see Diagnosing SP Switch2 problems. |
| The spmon, hmmon, or hmcmds commands fail. | System Monitor problem | Go to Diagnosing System Monitor problems |
| SP Perspectives is having trouble starting or running. | SP Perspectives problem | Go to Diagnosing Perspectives problems on the SP System |
| Cannot monitor or operate hardware controls, cannot power frames, nodes, switch on or off. | Hardware problem or System Monitor problem | Go to Diagnosing System Monitor problems |
| The configuration indicated by the SDR and Perspectives do not match your system configuration. | Frame Supervisor connectivity problem. | Go to Diagnosing System Monitor problems. |
| 3DigitDisplay indicator in the SP Hardware Perspective
displays three-digit codes.
LED/LCD displays present for a given node. | Hardware or software problem | Check SP-specific LED/LCD values to see if the code is listed there.
If not, see Other LED/LCD codes. Also, refer to IBM RS/6000 Problem Solving Guide, SC23-2204 |
| Node hangs, cannot access system via ping or a remote command, or node crashes with 888 in the 3DigitDisplay indicator. | Hardware or software problem | Go to Producing a system dump |
| You have an orange icon at any level of the System Monitor topology display. | System connectivity problem | Go to Diagnosing system connectivity problems |
| Cannot ping on the external network, remote commands or telnet and rlogin commands fail. | System connectivity problem | Go to Diagnosing system connectivity problems |
| User access problems, cannot log in, password is not valid, cannot get to home directory. | Software problem | Go to Diagnosing User Access problems |
| You get an error message in response to an SP command on the control workstation. | Hardware or software problem | Look up the message in PSSP: Messages Reference and follow the action suggested. |
