3. Be sure the hard drive is properly cabled and terminated if necessary.
4. Be sure the hard drive data cable is working by replacing it with a known functional cable.
5. Run Insight Diagnostics ("HP Insight Diagnostics" on page 55) and replace failed components as
indicated.
No hard drives are recognized
Action:
1. Be sure no power problems (on page 27) exist.
2. Check for loose connections (on page 11).
3. Be sure that the controller supports the hard drives being installed.
4. Be sure the controller has the most recent firmware.
Hard drive is not recognized by the server
Action:
1. Check the LEDs on the hard drive to be sure they indicate normal function. Refer to the server
documentation or the HP website (http://www.hp.com
) for information on hard drive LEDs.
2. Be sure no loose connections (on page 11) exist.
3. Remove the hard drive and be sure the configuration jumpers are set properly.
4. If using an array controller, be sure the hard drive is configured in an array. Run the array
configuration utility.
5. Be sure the drive is properly configured. Refer to the drive documentation to determine the proper
configuration.
6. If it is a non-hot-plug drive, be sure a conflict does not exist with another hard drive. Check for SCSI
ID conflicts.

A new hard drive is not recognized
Action:
1. Be sure the drive bay is not defective by installing the hard drive in another bay.
2. If the drive has just been added, be sure the drive is supported. Refer to the server documentation or
the HP website to determine drive support.
3. Run Insight Diagnostics ("HP Insight Diagnostics" on page 55) and replace failed components as
indicated.
4. If the drive is a replacement drive on an array controller, make sure that the drive is the same type
and of the same or larger capacity than the original drive.
