Symptoms

There have been several reported incidents of CPU faults reported on the ZS4-4 Storage Appliance.

These appear to be transient errors and can be cleared BUT may re-appear on reboot.

These do not actually appear to be CPU hardware issues (CPU replacement is generally NOT required), but are a result of a 'downrev' BIOS issue.

This issue may manifest itself as an 'unexpected' reboot of the system.

The CPU 'fault' may be shown as a faulty component and various associated FMA/alerts/faults displayed in the logs, including :

•     CPU shown as 'faulted' in the BUI 'maintenance hardware' view
•     Maintenance problem code = SPX86A-8002-RK or SPX86A-8002-H0
•     'fmadm' - Fault class : fault.io.intel.iio.vtd-fatal
•     'fmadm' - Fault class : fault.io.intel.iio.pcie-fatal
•     Alert description 'An event was received indicating a fault was diagnosed by another fault manager' (code is SPX86A-8002-H0 and/or SPX86A-8002-RK)
•     ILOM snapshot information:
  • Uncorrectable CPU-complex Error
  • ereport.cpu.intel.quickpath.llc_timeout
  • fault = fault.cpu.intel.timeout@/SYS

Example: CPU shown as 'faulted' in the BUI 'maintenance hardware' view
