2. Be sure each processor is supported by the server and is installed properly. For processor requirements, see the server documentation. 3. Be sure the server ROM is current. If an "unsupported processor detected" message is displayed, see "Unsupported processor stepping with Intel® processors (on page 83)." 4. Be sure you are not mixing processor stepping, core speeds, or cache sizes if this is not supported on the server. For more information, see the server documentation. CAUTION: Removal of some processors and heatsinks require special considerations for replacement, while other processors and heatsinks are integrated and cannot be reused once separated. For specific instructions for the server you are troubleshooting, refer to processor information in the server user guide. 5. If the server has only one processor installed, replace it with a known functional processor. If the problem is resolved after you restart the server, the original processor failed. 6. If the server has multiple processors installed, test each processor: a. Remove all but one processor from the server. Replace each with a processor terminator board or blank, if applicable to the server. b. If the server includes PPMs that are not integrated on the system board, remove all PPMs from the server except for the PPM associated with the remaining processor. c. Replace the remaining processor with a known functional processor. If the problem is resolved after you restart the server, a fault exists with one or more of the original processors. Install each processor and its associated PPM (if applicable) one by one, restarting each time, to find the faulty processor or processors. At each step, be sure the server supports the processor configurations. Tape drive problems The following sections include the most common tape drive issues. Actions are listed in the order that they should be tried. If the issue is resolved, it is not necessary to complete the remaining actions. All actions may not apply to all tape drives. For detailed tape drive guided troubleshooting information, see the HP website (http://www.hp.com/support/gts). To download HP StorageWorks Library and Tape Tools, see the HP website (http://www.hp.com/support/tapetools). For more information about common tasks, see the HP website (http://www.hp.com/support/lttfaq). Stuck tape issue Action: 1. Manually press the Eject button. Allow up to 10 minutes for the tape to rewind and eject. 2. Perform a forced eject: a. Press and hold the Eject button for at least 10 seconds. b. Allow up to 10 minutes for the tape to rewind and eject. The green Ready LED should flash. 3. Power cycle the drive. Allow up to 10 minutes for the drive to become ready again. Hardware problems 49
