Server Model R4700 G6
HDM Version 1.75
iFIST Version 1.71
Problem Description
The customer used iFIST to inspect the 8 R4700 G6 servers, and the following two identical alarms appeared in each server inspection result
| Component | CPU |
| Total test cycles | 1 |
| Test results | Error |
| Failure info | Description:The negotiated UPI link rate is too low. Level:Major Advice: 1. Identify whether the pins of the CPU under test are bent or polluted. 2. Re-plug the CPU under test. 3. Replace the CPU under test. 4. Replace the motherboard |
| Component | AHCI-/dev/nvme0n1 |
| Total test cycles | 1 |
| Test results | Error |
| Failure info | Description:The SSD's bandwidth does not reach the nominal value. Level:Minor Advice: 1. Re-plug the PCIe/NVME SSD. 2. Re-plug the devices on the physical link. 3. Replace the PCIe/NVME SSD. |
Process Analysis
8 servers with the same alerts, most likely caused by software. So try to upgrade HDM Version.
However, after upgrading HDM to the latest version, there are still alarms generated.
After in-depth analysis of the alarm generation mechanism of iFIST by R&D, it was found that this version of iFIST did not adapt the CPU and array card models of the server, so this alarm was generated after the inspection.
CPU Model: INTEL(R) XEON(R) PLATINUM 8568Y+
RAID Card Model: RAID-MARVELL-SANTACRUZ-LP-2i
Solution
After confirming that the hardware is working properly, these alerts can be ignored and do not affect the server. A new iFIST version will be released in January 2025 that will address this adaptation issue.
