This health check tool is designed to triage common and performance issues reported for DDVE system.

This document highlights minimum, recommended, and latest code versions for Dell Technologies Enterprise and Data Center Infrastructure products. Dell carefully evaluates and monitors code deployment data to ensure that product releases meet our stringent expectations to provide our customers with reliable products and solutions.

A boot-time issue may occur on systems using Intel X710 network adapters where network interfaces are not correctly detected during system startup. This happens when network cables or SFPs are connected during power-on, leading to incorrect NIC enumeration by system firmware before the operating system loads.

This article identifies the commands and steps required to configure Cloud Tier or otherwise known as Long Term Retention (LTR) on Data Domain systems running Data Domain Operating System (DDOS) 6.0 and later versions.

DD Management Center is not able to retrieve current data from the managed system. Information reported on DD Management Center may not reflect the current status of managed system.

To upgrade Data Domain appliances with additional storage tiers, such as Cloud Tier (LTR), Extended Retention, or Cache Tier, minimum platform hardware requirements must be met, prior to installing licenses or allocating capacity to a new tier. When required hardware or licenses are missing or misconfigured, the license for the feature cannot be installed or the creation or expansion of a tier is blocked.

Data Domain Virtual Edition (DDVE) system upgrade fails with filesystem shutdown error.

Microsoft Application Agent (MSAPPAGENT) takes a SQL backup of a large database, over 200 TBytes in size. The full backup runs over 24 hours. When the backup fails, users are locked out until the backup ends.

When a vault Data Domain fills up, symptoms include high capacity usage, poor deduplication, and expiration failures. The root cause is inadequate capacity planning, improper backup configuration, and unchecked saveset accumulation across DD, NetWorker, Avamar, and Cyber Recovery.

This article provides a clear, model‑by‑model breakdown of the recommended BIOS and iDRAC firmware versions for each supported DDOS release across the DD series platforms. It is designed to help you quickly confirm which firmware levels align with your system’s DDOS version, reduce compatibility issues, and ensure that your environment stays stable, secure, and fully supported. Use the tables below to find the right BIOS and iDRAC versions for your specific DD model in seconds.

This article describes how to change cloud profile from STANDARD to STANDARD-IA Storage Class and how to convert existing objects in AWS cloud tier bucket from STANDARD to STANDARD-IA Storage Class.

Data Domain Operating System (DDOS) 8.4 introduced a system health check feature. When checking cloud health, it may incorrectly report an issue connecting to the cloud endpoint port.

The Data Domain appearing as "red" in the Avamar User Interface (AUI) or Avamar Administrator console can be caused by several different issues. This guide provides a structured troubleshooting path and directs to relevant articles for diagnosing and resolving these conditions.

This article provides download links and status information for current PowerProtect Data Domain Operating System (DDOS) releases, including feature and Long‑Term Support (LTS) versions. It also outlines upgrade considerations, documentation references, and supported platforms.

After a disk replacement, the new disk information is not updated on the Data Domain Operating System (DDOS), and the alert remains.

This article explains an issue with the Data Domain Virtual Edition (DDVE) system recovery function caused by a different encryption key format between the old and new systems.

Data Domain systems automatically monitor for hardware, software, and environmental conditions that may require service. When certain alerts occur, the system can automatically open a Dial Home Service Request (SR), either immediately or after a short monitoring period. This proactive SR creation ensures timely support while reducing unnecessary or duplicate cases.

When the https or "ca trusted-ca" certificate expires on a Data Domain, it causes issues when trying to access the web UI. Generating a new certificate resolves the issue.

Determining the file system cleaning schedule and setting the schedule

DD enforces stricter FEC validation during interface configuration; errors originate from DD, not Cyber Recovery (CR). CR (by 'securecopyanalyze') only triggers validation, while DDOS enforces it. FEC is unsupported on some Intel NICs (for example, X710-T4L), so code must ignore registry FEC settings.

How to reset or regenerate certificates due to expiration (or misconfiguration).

This article outlines the procedure for performing an offline firmware update on Aries-KP model drives (HUS72604CLAR3000 and HUS72604CLAR4000) from version N9C0 to NE70.

Data domains with intel cards interface links may go down with tx_timeout recovery unsuccessful, device is in an unrecoverable state.

A daily SupportAssist alert may be generated on Data Domain systems at 08:00, reporting: Error communicating with ESRS gateway This alert is caused by the am_email.sh script invoking connectemc_send during the SupportAssist alert-summary process. As a result, the system generates HTTP 401 errors and raises the ESRS gateway communication alert.

After upgrading DDOS, receive the error "Default authentication mode for DD Boost clients does not provide over-the-wire encryption."

This knowledge base article addresses Data Domain OS compatibility and readiness for leap second events. It also covers frequently asked questions that have been verified to ensure proper handling of leap second adjustments within Data Domain environments.

Dell PowerProtect Data Domain systems provide two CLI commands to diagnose system health: system health check (DDOS 8.4.0 and later) for combined hardware and software diagnostics, and support healthcheck hardware (DDOS 7.10.1.40 and later) for hardware-only diagnostics. Both commands evaluate component status, report failures, and provide recommended remediation steps. This article explains how to run each command, interpret the output, and manage the proactive health check schedule.

Upgrading DDOS affects not only the PowerProtect DD/Data Domain system, but also every application, plug‑in, client, and protocol that interacts with it. This guide walks you through how to use E‑Lab Navigator to confirm compatibility before upgrading DDOS, with examples for each protocol and integration. This article is written for clarity and practicality, so you can confidently validate your environment and avoid upgrade‑related outages.
