Message Action Hard drive x removal detected (level-critical; hard drive x has been removed) v Information only, take action as appropriate. Undetermined problems Note: When troubleshooting a problem with the HS20 Type 8832, it must be determined whether the problem is a blade server problem or a problem with the BladeCenter unit. v If the BladeCenter unit contains more than one blade server and only one of the blade servers exhibits the problem, it is likely that it is a blade server problem. v If all of the blade servers exhibit the same symptom, it is probably a BladeCenter unit problem; for more information, see the IBM BladeCenter Hardware Maintenance Manual. Use the information in this section if the diagnostic tests did not identify the failure, the devices list is incorrect, or the system is inoperative. Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. To reset the CMOS data, remove the battery for 15 minutes, and then reinstall the battery. If you suspect that the BIOS code is damaged, see "Recovering the BIOS code" on page 25. Check the LEDs on all the power supplies of the BladeCenter unit where the blade server is installed. If the LEDs indicate the power supplies are working correctly, and reseating the blade server does not correct the problem, complete the following steps: 1. Check that the front panel is connected to the system board. 2. If no LEDs on the front panel are working, replace the front panel; then, try to power up the blade server from the BladeCenter web interface (see the BladeCenter documentation for more information). 3. Turn off the blade server. 4. Remove the blade server and remove the cover. 90 BladeCenter HS20 Type 8832: Hardware Maintenance Manual and Troubleshooting Guide

If the BladeCenter unit contains more than one blade server and only one
of the blade servers exhibits the problem, it is likely that it is a blade
server problem.
v
If all of the blade servers exhibit the same symptom, it is probably a
BladeCenter unit problem; for more information, see the IBM BladeCenter
