Symptoms

If the described issue occurs, the failure signature observed is FMA fault ‘SPSUN4V-8000-YE - fault.io.pciex.bus-linkerr’

Impact:

Unable to use the NVMe drive in the system due to NVMe drive initialization errors seen in POST.

Changes

Contributing Factors:

SPARC S7-2 systems with NVMe cable p/n 7318517 and 7318496.

Regional Deployment Managers (RDMs) identified below have the list of affected systems and customers:

NAR: dennis.cairns@oracle.com
EMEA: roberto.donzelli@oracle.com
JAPAC: khee-huat.lim@oracle.com
LAD: sergio.alonso@oracle.com

This FCO is targeted only to systems in the list sent to RDMs.

Cause

A small number of SPARC S7-2 systems were shipped with NVMe cables that do not fully meet design specification and could lead to POST errors during NVMe drive initialization.

Solution

Target Completion Date: 08-Sep-2017

Hot Swap: No

Workaround:
