Data Domain Capacity Resolution Path.

This article addresses an issue with SAP HANA PIT recovery failing under Dynamic Tiering setup.

After upgrading IDPA example model dp4400, ethVX fails to communicate, failing either backups or replication or cyber replication.

This article provides information about DD Boost global authentication and encryption which is taken from the latest up-to-date information from DD OS 7.13 boost documentation. In this guide, "PowerProtect DD System," "the protection system," or simply "the system" sees PowerProtect DD Series Appliances running DD OS 7.4 or later and earlier PowerProtect DD systems.

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

The Health Alerts panel allows you to view messages from system services. This article discusses how to view and clear these messages.

Windows serve 2025 cifs shares fail to connect but all other previous versions of windows connect fine.

This knowledge base article explains how to safely move a Dell Data Domain system from one site to another. It covers premove validation, shutdown, postmove reconfiguration, and verification steps.

Use mminfo to extract deduplication statistics for a NetWorker save set on a Data Domain; the output follows version:cloneid:backup:pre‑compression:post‑compression and shows deduplicate compression process.

NetWorker is unable to mount the adv_file device because the volume is not in the media index.

This KB article explains how to use an external system for creating Certificate Signing Request, and create a signed certificate by an external CA, so that the resulting certificate may be imported in the Data Domain for use in HTTP (DD GUI through SSL)

The NetWorker vProxy solution is used to protect the vSphere environment. The file-level restore (FLR) fails for all Virtual Machines (VM) with the signature length error. Data Domain self-signed CA certificate has expired. Renew Data Domain certificate as shown in Dell KB 198864.

HA create command fails with either of these two errors: **** Failed to configure HA: unable to communicate with the peer node via the interconnect. Or **** Failed to configure HA: Communication with the peer node timed out.

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.

This guide explains what Dial Home is on Dell Data Domain systems, what data it sends to Dell, and how each connection method and report type works, while setting expectations for how these automated reports speed issue detection, simplify support, and improve system‑health visibility.

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.

Security scanning scripts and applications can have a major impact on Data Domain system performance.

This article describes a scenario in which an incorrect client ID was specified when configuring multifactor authentication.

After a System Controller Upgrade (headswap), Cloud Tier (CT) access may fail if the system passphrase on the new controller does not match the original passphrase. The Data Domain filesystem cannot decrypt the stored cloud profile, preventing connection to the Cloud Tier.

After deploying a new Data Domain Virtual Edition (DDVE) instance in Azure using OAuth authentication, the filesystem fails to start, and the object-store profile cannot be configured. This issue occurs due to token size limitations when using user-assigned managed identities.

Replication may post a warning when an unexpected segment is received. If replication can continue, it does so automatically.

The standby or passive node of a high availability (HA) pair does not report active tier unavailable, but the active node reports that HA is degraded.

Data Domain in a Cyber Recovery solution often has inaccurate cleaning estimates due to how fastcopies and deduplication works on the Data Domain.

When attempting to create a Cloud Tier (CT) device for a newly added cloud unit, the process fails with the error "Unable to create the data movement policy for mtree **** and cloud unit ***. HTTP response 500 indicates an error." This issue is caused by stale or incorrect configuration values in the Data Domain properties within NetWorker Management Console (NMC).

After upgrading Solaris to 11.4 SRU 78 or later, DDBoost Solaris clients stop using Distributed Segment Processing (DSP), also known as client‑side deduplication. Resulting in increased network usage and slower backup performance. The issue is caused by an OpenSSL upgrade (1.x to 3.0) that prevents the DDBoost plugin from correctly detecting Solaris system capabilities.

This KB provides links to the most referenced Dell Knowledge Base articles related to issues with Data Domain Serial Attached SCSI (SAS) components. Common SAS components are Host Bus Adapters (HBAs), Disk Array Enclosures (DAEs), and cabling.

To create a local console connection to the DD3300 system through the rear serial port.

This article explains the support, behavior, and limitations of using Low-Bandwidth Optimization with MTree replication on Data Domain systems.

This article provides best practices and configuration guidelines for applications with the Data Domain DD Boost File System Plug-In (BoostFS). In addition, the article contains insights and tips on how the application should be configured to maximize all the benefits of BoostFS.
