If a blade server cannot access the media tray, the problem could
be with the blade server, the blade server bay, the media tray, or the advanced management module.
Problem
A blade server is unable to access the media
tray in the BladeCenter S chassis.
Investigation
Perform these
steps to resolve the problem:
- Log in to the advanced management module and
view the event log to determine if there are service processor communication
errors for multiple blade servers. If so, see Service processor communication error displayed for multiple blade servers.
- If you are unable to select KVM from the front panel
of the blade server, make sure the KVM options are enabled:
- From the advanced management module Web
interface, click .
- Verify that the following options are checked:
- Enable local KVM switching
- Enable local media tray switching
- Check the System Status page to make sure that all the blade servers have
been discovered. Media tray selection will not work properly for any blade
for which status is being discovered.
- Check the power LED on the front of the blade server. This LED should
blink when the blade server is powered off and stay lit when the blade server
is powered on.
- Verify that the CD LED on the blade server lights up solid when pressed.
- If the LED blinks instead, wait 30 seconds to give the advanced management module time
to communicate with the blade server.
- If the LED still does not light up, press the CD button on another blade
server in the BladeCenter S chassis.
If it does not light up either, see Multiple blade servers cannot access the media tray.
Note: It is possible to get ahead of the advanced management module when
pressing media selection buttons between the blades. Always allow a few seconds
for the advanced management module to
respond before selecting another blade
- Determine whether the problem is with the blade server or the BladeCenter S chassis.
- Swap this blade with another blade in the BladeCenter S chassis that
works or just move the blade to an empty slot in the same chassis.
- If the CD button problem follows the blade, then suspect the blade.
- From the advanced management module Web
interface, click Firmware VPD to check the current
service processor (BMC) firmware level.
- Find firmware updates for the BMC. Look in the firmware
change history for and update the firmware if necessary.
You can find the
firmware by going to Sofware and device drivers - IBM BladeCenter and selecting
the blade server that you have installed.
- Call IBM support.
- If the CD button problem stays with the blade server bay, move the blade
back to the original bay and try again.
- If the problem persists, see Isolating component failures.
- If the blade server cannot boot or read data from the device in the media
tray
- Make sure the appropriate entry for the DVD drive is listed in the blade
boot sequence, shown in the advanced management module under .
- See Blade servers cannot communicate with the media tray.
- Verify that the DVD drive itself works with another blade server in the BladeCenter S chassis.
- If the problem seems to be a USB device, verify that the device is compatible
with the BladeCenter USB interface and the software running on the blade.
- Verify the latest device driver is installed.
- Try the USB device on a non-blade server or blade server in another chassis
running the same operating system type and version.
- Try another USB device.
- If no external USB devices work in the USB port, replace the media tray.
