Problem Description

Certain Network Convergence System (NCS) 5500 Series units listed in the Products Affected section might have earlier solid state drive (SSD) firmware versions that could experience file system/disk corruption or uncorrectable errors. This is specific to these two SSD series and firmware versions:

• D0MU027
• D0MU051

Background

An engineering failure analysis concludes that the impacted firmware versions are susceptible to failure scenarios and will exhibit failure symptoms as described in the Problem Symptom section.

Problem Symptom

This issue might cause these problems:

• Unable to run show commands, any commit changes, and install operations. The Route Switch Processor (RSP) can go into a boot loop after reboot.
• Generic I/O errors or anomalies when the packages are verified.
• Potential bad sectors on disk.

Workaround/Solution

In order to avoid the issues listed in the Problem Symptom section, Cisco recommends installation of a Software Maintenance Upgrade (SMU) for the Cisco IOS^® XR version which you currently run.

These SMUs are available to help you upgrade the system.

Cisco IOS XR Release	SMU Link	SMU Install Type
Cisco IOS XR 6.6.3	ncs5500-sysadmin-6.6.3.CSCwa74723.tar ncs5500-sysadmin-6.6.3.CSCwa32524.tar	Reboot
Cisco IOS XR 7.0.2	ncs5500-sysadmin-7.0.2.CSCwa74723.tar ncs5500-sysadmin-7.0.2.CSCwa32524.tar	Reboot
Cisco IOS XR 7.1.2	ncs5500-sysadmin-7.1.2.CSCwa74723.tar ncs5500-sysadmin-7.1.2.CSCwa32524.tar	Reboot
Cisco IOS XR 7.2.2	ncs5500-sysadmin-7.2.2.CSCwa74723.tar ncs5500-sysadmin-7.2.2.CSCwa32524.tar	Reboot

How To Identify Affected Products

Use one of these options in order to determine if a device needs to be upgraded:

• Verify your serial numbers through the list of products that were originally shipped with the impacted firmware version with the Serial Number Validation Tool. See the Serial Number Validation section of this field notice for more information.
• If there is no reason to believe the firmware has been updated since the product purchase, validate the SSD series and firmware version with the show smart-monitor location ALL | inc "Device Model|Firmware Version" command.

  sysadmin-vm:0_RP0# show smart-monitor location ALL | inc "Device Model|Firmware Version"
  Day MMM  DD HH:MM:SS.337 UTC+00:00
  Device Model:     Micron_5100_MTFDDAV240TCB
  Firmware Version: D0MU075

If the device model matches your device and the firmware version is anything other than D0MU075, an upgrade is recommended.

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.
