12 SPARC Enterprise T5120 and T5220 Servers Product Notes • October 2007

Though no error or fault is reported, it is easy to identify due to the fact that when

this problem is encountered, no PCIe I/O devices will be available to the system. If

you power-on the system or reset the domain and try and boot from a disk or

network device and you get an error similar to the following:

At the OpenBoot prompt issue the command show-devs. Check the output to for

PCIe devices. If there are no devices then you have encountered this problem.

Note – All PCIe devices begin with the path /pci@0/pci@0.

Corrective Action:

If this problem is encountered you should take down all domains and power off the

system. Next run Power On Self Test (POST) to identify whether this is a persistent

failure or not.

To enable POST use the SP ALOM CMT compatibility CLI command setsc and

enable POST to run at max level.

For example:

Next, power on the system and POST will execute testing the CPU, Memory and IO

sub-systems. If the problem is persistent POST will fail the PCIe root complex and

disable the component /SYS/MB/PCIE.

If POST does detect the problem, the system's motherboard will need to be replaced.

Please contact your sales representative to schedule a motherboard replacement.
