Common reasons why Led 000 is displayed on the system's LED panel during boot.
What is the cause(s) of a network boot hang at LED 000?
Led 000 is displayed on the system's LED panel during a network or boot when the boot image does not contain the needed device support or kernel support filesets required to boot the client.
NOTE: In the items below, any reference to "installed on server" may also be assumed to be "be installed into the NIM Spot" for customers using the NIM Resource Network boot option instead of the Classic Boot option.
Commonly, one of the following has occured:
1. When the boot client was added, an incorrect "Client platform/kernel type" was specified. For example: If the boot client is a 4-way F50 which requires a CHRP/MP platform and kernel type, but the RS6K/UP platform and kernel was specified incorrectly.
2. The boot server did not have the correct kernel support installed before creating the boot image.
For example: If the boot client is a 4-way F50 which requires the multiprocessor kernel fileset, bos.mp, but only the bos.up fileset installed.
3. The boot server did not have the correct device support installed before making the boot image.
For example: If the boot client has a graphics console / adapter that requires fileset devices.isa_sio.PNP0401.rte, but the boot server only has an ASCII console with it's respective fileset.
4. The appropriate device support and / or kernel support filesets have been installed onto the boot server, but the boot server was not rebooted prior to creating / adding the boot client or creating the boot image.
5. The appropriate device support and / or kernel support filesets have been installed onto the boot server, and the boot server has been rebooted, but the network boot client was not updated to reflect the change (aka rebuilding the boot image).
6. There may be a firmware, or other SMS related, defect for the boot client.
7. There may be a AIX updates / fixes required to support certain hardware components for the boot client that were not installed onto the boot server before making the boot image.
