Defect Information

Defect ID	Headline
CSCvw93587	Power on buffer overrun Error at 3.2 Years in SSD Firmware

Problem Description

Because of a flaw in the Solid State Drive (SSD) firmware, the SSD will no longer respond after approximately 3.2 years of cumulative operation. A restart of the system allows the drive to operate for another 1008 hours (six weeks), after which it again becomes unresponsive.

Background

After approximately 3.2 years (28,224 accumulated Power On Hours (POH)), a memory buffer overrun condition occurs that triggers the firmware event. This causes the drive to become unresponsive until the drive is power-cycled. No data loss will occur when the memory buffer overrun firmware event occurs. A power-cycle restores normal operation of the drive. The drive continues to operate normally for approximately six weeks (1008 additional accumulated POH), at which time the drive again becomes unresponsive. Another power-cycle of the drive re-initiates the 1008-hour window.

Problem Symptom

The Cisco 1000 Series Connected Grid Router (CGR 1000) Compute Module no longer passes network traffic.

Workaround/Solution

Workaround

Restart the system in order to temporarily recover from this problem. However, this failure will reappear after 1,008 hours of operation.

Solution

Upgrade the firmware of the SSD.

Cisco recommends to upgrade the firmware of the SSD proactively before the uptime reaches 28,224 hours. This will prevent recurrence of the issue and disruption to the network and operations.

For CGR 1000 Compute Modules, upgrade to the software version below in order to update the SSD firmware. The software is available to download from the Cisco Software Download Center.

Release: 1.14.0.3 or later

How To Identify Affected Products

Products with model number CISCO_IT_SSD_MTFDDAT120MBD-1AK12ITYY/CISCO_IT_SSD_MTFDDAT060MBD-1AK12ITYY and firmware version MG02 are affected.

In order to determine whether your model number and firmware version are affected, complete these steps:

1. Access the Connected Grid Module with the server-module <mod-no> console command and log in with the configured credentials.

2. Enter the smartctl -a /dev/sda | egrep 'Firmware|Model' command in order to check the model number and firmware version.

The released version is Release 1.14.0.3.

Serial Number Validation

Cisco provides a tool to verify whether a device is impacted by this issue. In order to check the device, enter the device's serial number in the Serial Number Validation Tool.

Note: For security reasons, you must click on the Serial Number Validation Tool link provided in this section to check the serial number for the device. Use of the Serial Number Validation Tool URL external to this field notice will fail.
