Description

SLN315518_en_US__1icon This issue and solution is only applicable to the following systems:
- Dell XC6320 Web-Scale Converged Appliance
- Dell XC630 Web-Scale Converged Appliance
- Dell XC730 Web-Scale Converged Appliance
- Dell XC430 Web-Scale Converged Appliance
- Dell XC730XD Web-Scale Converged Appliance

Under the following Firmware Conditions:
- Running SATADOM 3IE3 (Dell Part Numbers K9R5M, FXGNM) with firmware less than S670330N

Dell Technologies are aware of a scenario where the specified XC systems listed above, running on SATADOM 3IE3 V2, may fail to boot if the device is running on firmware version 301N (S560301N) for an extended time.


 

Cause

Cause

During normal operations, SATADOM devices on the system complete a data consistency check following a device reset or power reset. If the consistency check encounters excessive ECC events which cannot be corrected on the device, the firmware of the SATADOM will protect the host from invalid data by disabling the SATADOM. The device will then become unavailable at a BIOS level causing a boot failure of the XC host.

This mechanism will cause the same issue during any of the following processes:

  • During the update from firmware 301N to 330N
  • During the SATADOM update process, either using the Nutanix LCM (Lifecycle Manager) or the ISO firmware update method
  • During the update from firmware 301N to anything greater than S670330N on Dell Part Number K9R5M

This issue does not affect SATADOMs which are already running firmware version 330N, as background memory block management is implemented in this version.


 

Resolution

Solution

A fix for this issue was implemented in the 330N (S670330N) firmware release. As of this release, the management of ECC errors is active in the background processes of the SATADOM. The recommended solution for this issue is to update SATADOM firmware to 330N (S670330N).
Current firmware for your device can be obtained from the Lifecycle Manger (LCM). You can find out how to perform this action from the Dell EMC XC940 XC Series Appliance and XC Core System Solutions Guide. An ISO can also be downloaded from the Nutanix website.
