Third-party device problems
1.
See the device documentation to be sure the device is properly installed.
2.
If the device is the only device on a bus, be sure the bus works by installing a different device on the
bus.
3.
Be sure the latest device drivers are installed.
4.
Uninstall the device. If the server functions without the removed device, the problem might exist with
the device rather than the server. Either the server does not support the device, or a conflict exists
with another device.
5.
Remove other device. If the server functions properly, a conflict exists with another device. If the
device still does not function properly, see the server and operating system documentation to be sure
that the server and operating system support the device.
Internal system problems
CD-ROM and DVD drive problems
1.
System does not boot from the drive
o
Be sure no loose connections exist.
o
Be sure the media from which you are attempting to boot is not damaged and is a bootable CD.
o
Be sure legacy support for a USB CD- ROM driver is enabled in the BIOS and be sure that
the drive boot option in the BIOS is set up so that the server boots from the CD-ROM drive first.
o
If the data read from the driver is inconsistent, orif the drive cannot read the data, be sure that the
inserted CD or DVD format is valid for the drive. For example, be sure not to insert a DVD into a
drive that only supports CDs.
2.
Drive is not detected
o
Be sure no loose connections exist.
o
See the drive documentation to be sure cables are connected as required.
o
Be sure the cables are working properly. Replace with known functional cables to test whether the
original cables were faulty.
o
Be sure the USB port functions normally with a USB CD-ROM drive.
o
Be sure legacy support for a USB is set enabled in the BIOS.
Drive problems (hard drives and solid state drives)
1.
Drives are not recognized
o
See the hard drive and server documentation to be sure the hard drive is compatible with the
server.
o
See the SAS RAID card documentation to be sure the RAID card is compatible with the server.
o
Be sure no power problems exist.
o
Be sure no loose connections exist.
o
Be sure the driver or backplane is connected properly.
o
Be sure legacy support for SAS is set up correctly.
o
Connect only one hard drive directly from the SATA port to determine if the server is causing the
problem.
