Chapter 13: Troubleshooting
Important: Whenever the LDVR-3U is physically moved (this includes shipping the
LDVR-3U via any mail carrier) you should re-seat each hard drive before
powering up the unit for the first time. This is done by doing the following to
each drive WHILE THE 3U IS POWERED OFF: unlock the drive, pull it
out, gently but firmly push it back in until it does not go back any further, re-
lock the drive. This prevents system startup problems and random
intermittent drive errors due to IDE data connectors working themselves
loose inside the drive bays and causing faulty connections.
Problems and Solutions
The system doesn't begin booting (no BIOS runs) when the storage controller
board is installed, but boots OK when the board is removed.
Check the cabling between the drives and the storage controller board. A
cable plugged in upside down can prevent your system from running its
BIOS. Blue connectors must always be connected to the controller channels/
port and black/gray connectors connected to the drive bays. Otherwise, long
delays during system startup occur. You must also connect an available drive
power cable to the new/upgraded drive bay.
The 3ware BIOS scrolling messages never appear.
The storage controller board is not installed properly. Reinstall the hardware
and reboot.
The 3ware BIOS scrolling messages stop midway.

The storage controller board is detected, but the disks may not be connected
to their power source. Reconnect to their power source and reboot.
The 3ware BIOS displays the following error message:
RAID configuration only support identical drives. Please check and replace
unidentical drives.
The current hardware installation includes a combination of disk drives that
are not identical in manufacturer, model, and size. Replace the appropriate
drives.
