Basic Troubleshooting

Use this basic troubleshooting information as a starting point in detecting problem components. Begin with step 1 in Basic system checkout and proceed as directed.
Note:For more detailed troubleshooting information, refer to specific troubleshooting sections in this chapter.

Basic system checkout

  1. Is the Power-on LED on or blinking? If yes, go to step 3. If no, go to step 2.
  2. Are the power cords plugged in and attached to a good power supply? If yes, go to step 4.
  3. Is the Power-on LED blinking? If yes, go to step 9. If no, go to step 10.
  4. Is the System Error LED on? If yes, go to step 5. If no, go to step 6.
  5. Open the box and use the diagnostics panel to determine which power supply to replace (see Replacing hot-swap power supplies).
  6. Is the system fan on? If yes, go to step 7. If no, go to step 8.
  7. Replace the external LED card.
  8. See Power Supply LED errors to troubleshoot power problems. This will determine if you need to replace a system board or fan.
  9. Press the Power button. Then, go to step 9.
  10. Is the POST Complete (OK) LED on? If yes, go to step 12. If no, go to step 11.
  11. Connect the keyboard and monitor. Follow the directions for POST error determination (see POST error codes).
  12. Connect the keyboard and monitor. Then, reboot the appliance. If the message Uncompressing Linux... OK, booting the kernel appears, go to step 14. If the message does not appear, go to step 13.
  13. Reboot the appliance and follow the steps in Starting the diagnostic programs to perform a check of the system IDE drive that contains the system code load. If the IDE drive is bad, go to step 16. If the IDE drive is good, go to step 15 to obtain a new system image.
  14. Follow the steps in "Verifying the network connection is good."
  15. Use the Recovery CD. (See Recovering the IBM IP Storage for information on using the Recovery CD.)
  16. Replace the IDE drive (see Installing an IDE (non-hot-swap) hard drive or CD-ROM). Then, go to step 15.

Verifying the network connection is good

  1. Do you have access to the Administrative Console from the IP-connected management console? If yes, go to step 3. If no, go to step 2.
  2. Are you able to ping the appliance's IP address from the IP-connected management console? If yes, go to step 5. If no, go to step 4.
  3. Check the LEDs on the Operator Information panel and act appropriately.
  4. Is the Link LED on? If yes, go to step 7. If no, go to step 6.
  5. Press Reset and allow the appliance to reboot. Then, return to step 1.
  6. Check the network cabling and connections. Is the problem solved? If yes, verify step 1 and continue system operation. If no, go to step 7.
  7. Connect a keyboard and monitor. Run the Gigabit Ethernet diagnostics diskette (see Using the diagnostics diskette).
    Note:The diagnostics diskette is available at www.ibm.com/storage/support/nas.
