Missing FRU device - Processor 0

If you do show the Alert level 7 “Missing FRU device - Processor 0”, continue to the next step.

Step 11. Insert a processor into CPU slot 0. When you add the processor and turn on system power, the

cooling fans should turn on and stay on, and the DF and S command output should look

something like this:

FRU IDs:

--------

0032-Processor 0 0036-Processor 0 RAM 0001-Comm Module

0002-Disk Backplane 0003- Mezzanine Board 0128-DIMM0A

0129-DIMM0B 0000-Motherboard

If the installed FRUs are all functional, the system should initiate POST on all processors. Observe

the system console output through “Live Events” to ensure that POST initiates and completes

without error.

If POST does not start after a few seconds, suspect some sort of system board or processor problem.

Typical problems show up in the SEL or FWP. If the IPMI event logs do not point to a root cause,

escalate to bring in expert assistance.

CPU/Memory/SBA

All of the CPU, Memory controller, DIMMs, and SBA (I/O rope controller) functions reside on the server blade

FRU. This section discusses the roles of physical CPUs and physical memory ranks.

Troubleshooting Server Blade CPU

Each server blade supports 1 or 2 IPF processor modules. This results in two physical CPUs, when two IPF

processor modules are installed in server blades.

Each physical IPF CPU core contains logic to support one physical thread. (Note that the operating system

kernel attaches one or more software processes to each available thread, so in multiple processor server

blades, having more threads means all software processes are launched and executed more rapidly.)

IPF Processor Load Order

For a minimally loaded server blade, one IPF processor module must be installed in CPU slot 0. Slot 0 is the

slot closer to the server blade chassis. Install a processor of the same version into CPU slot 1 if purchased.

Processor Module Behaviors

All physical CPUs become functional after system power is applied. Each CPU is in a race to fetch their

instructions from their CPU’s instruction and data caches to complete early self test and rendezvous.
