No hard drives are recognized
Action:
1. Be sure no power problems (on page 62) exist.
2. Check for loose connections (on page 50).
3. Be sure that the controller supports the hard drives being installed.
4. Be sure the controller has the most recent firmware.
5. If the controller supports license keys and the configuration is dual domain, be sure the license key is
installed.
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 50) 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.
7. Be sure the correct drive controller drivers are installed.
A new drive is not recognized
Action:
1. Be sure the drive is supported. To determine drive support, see the server documentation or the HP
website (http://www.hp.com/go/bizsupport).
2. Be sure the drive bay is not defective by installing the hard drive in another bay.
3. Run HP Insight Diagnostics (on page 40). Then, replace failed components as indicated.
4. When the drive is a replacement drive on an array controller, be sure that the drive is the same type and
of the same or larger capacity than the original drive.
Data is inaccessible
Action:
1. Be sure the files are not corrupt. Run the repair utility for the operating system.
2. Be sure no viruses exist on the server. Run a current version of a virus scan utility.
3. When a TPM is installed and is being used with BitLocker™, be sure the TPM is enabled in RBSU
("ROM-Based Setup Utility" on page 38). See the TPM replacement recovery procedure in the
operating system documentation.
4. When migrating encrypted data to a new server, be sure to follow the recovery procedures in the
operating system documentation.
