BladeCenter QS22 Type 0793: Problem Determination and Service Guide
Description
The blade server firmware was not
able to create a device tree node. This
might indicate a blade server firmware
problem.
Action
1. Reboot the blade.
2. Power down then remove and
reinstall the blade server in the
BladeCenter unit.
3. If the error started after a SAS
Expansion Card firmware upgrade
or a blade server firmware
upgrade, consider a rollback to the
previous firmware versions. Check
with the documentation at
http://www.ibm.com/systems/
bladecenter/support/ to verify
whether rollback is possible.
4. Ensure that the blade server is at
the latest firmware level.
5. If the error started after an Open
Firmware script change (for
example, a custom startup script),
verify the script.
6. If the error started after activating
an Open Firmware script, (for
example by setting the
use-nvramrc? configuration
variable), verify the script.
7. Reproduce the blade server Open
Firmware environment (firmware
version, scripts, configuration
variables, hardware configuration
and so on) with another blade
server.
8. If the error started after hardware
was added or removed, consider
rolling back to the original hardware
configuration.
