Chapter 6 Troubleshooting
4. If a disk array controller is being used and the NOS is installed on a hardware array/container, verify
that the array/container is in an optimal state by accessing and checking the disk array controller’s setup
utility during startup.
5. Boot to a DOS boot disk and check the partitions to make sure the primary partition is active.
If the problem persists, contact the HP Customer Support Center for further troubleshooting assistance.
Server Stops or Hangs While Starting Up
Typically, if the HP Server hangs before the end of POST completes, the problem is possibly a hardware
problem or failure. If the HP Server hangs after POST completes, the problem is possibly due to an
incorrectly configured or corrupt driver, operating system, application program, or a media (disk drive) error.
If the HP Server stops working or hangs starting up:
1. Review the Troubleshooting Checklist at the beginning of the chapter before continuing.
2. Try to verify exactly where the HP Server is stopping during POST. For example: is the HP Server
stopping at the memory count or on a SCSI controller? Look for any error messages and listen for
any beep codes and make note of them for further assistance in troubleshooting the problem.
3. If the failure persists, verify there is not a hardware problem by running HP DiagTools.
If the problem persists, contact the HP Customer Support Center for further troubleshooting assistance.
Power Problems
NOTE The installation of the HP Server Remote Management Card (optional accessory) changes
the Power Supply Status LED behavior on the front panel. See Chapter 1 Front Panel LED
Indicators in this manual.
NOTE The HP Server tc3100 supports the ACPI (Advanced Configuration and Power
Management Interface) standard, which is a key component of a NOS's directed power
management. The supported features are only available when an ACPI-compliant NOS is
installed on the Server.
Refer to Chapter 1 in this manual BEFORE doing any further troubleshooting to verify
that the HP Server tc3100 is not in a sleep mode.
A blinking green power LED indicates the HP Server tc3100 is in a sleep mode.
1. Verify the HP Server’s power cord is plugged in to a known good power source.
2. Is the On/Off/Sleep LED on the front of the HP Server tc3100 a steady green, which indicts it is getting
power?
3. Remove the HP Server form any UPS or PDU and connect the HP Server directly to a power source.
4. Verify the AC power source is good:
a. Verify the circuit breaker for the AC power outlet.
b. If the breaker was off, verify all devices connected to the HP Server share the same circuit breaker
and are the only devices on it.
c. Reset the circuit breaker after reconfiguring the devices if needed.
d. Verify the AC power outlet is not faulty by plugging in a known good device.
