本文介绍与 Baseboard Management Controller （BMC）（在基于 Dell PowerEdge 的平台上也称为 iDRAC）相关的警报的原因和解决方案。BMC 是一款嵌入式控制器，用于监视系统运行状况参数，例如温度、风扇速度、电源状态和电压。当 BMC 变得无响应或出现故障时，Data Domain 系统将生成警报。

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.

本文介绍 DD Boost 如何为备份和恢复流量强制使用动态接口组 （DIG） 接口。启用接口强制实施后，DD Boost 会话必须使用 DIG 接口，而不是回退到连接接口。

本文介绍如何通过编辑 boostfs.conf 文件来配置和装载多个 BoostFS for Windows 存储单元。它介绍了 storage-unit 参数的工作原理、如何定义基于 UNC 的装载部分以及如何为独立装载分配驱动器号。

本文提供有关如何在 Data Domain 系统上禁用 IPv6 的信息;默认情况下，IPv6 处于启用状态，客户可能需要将其禁用。

Cyber Recovery 数据避风港解决方案中的 Data Domain 通常由于 FastCopy 和重复数据消除在 Data Domain 上的工作方式而导致的清理估计不准确。

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.

NetWorker vProxy 解决方案用于保护 vSphere 环境。所有虚拟机 （VM） 的文件级还原 （FLR） 均失败，并显示签名长度错误。Data Domain 自签名 CA 证书已过期。续订 Data Domain 证书，如戴尔知识库198864中所示。

本文介绍如何删除受 Retention Lock Governance （RLG） 保护的 MTree。启用治理的 MTree 在删除之前必须为空，此过程概述了如何恢复治理锁定、删除数据、验证 MTree 大小以及删除 MTree。

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.

本文提供了使用 Data Domain DD Boost 文件系统插件程序 （BoostFS） 的应用程序的最佳实践和配置指南。此外，本文还包含有关如何配置应用程序以最大限度地发挥 BoostFS 的所有优势的见解和提示。

Data Domain sysadmin/SO password resets no longer require Support intervention when running DDOS (7.10.1.40 or newer). A password reset token is sent to the registered email address. Copy the token to a supported USB drive, insert it into the system, and log in as sysadmin or security officer to reset the password.

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.

本知识库文章重点介绍使用 Data Domain 自动化 TC 脚本提取自动化升级前评估所需的日志的步骤。

This article describes NetBackup command‑line tools that can be used to validate Virtual Tape Library (VTL) functionality during initial configuration or when troubleshooting potential device issues. These commands allow testing outside of the NetBackup UI to confirm device visibility, robot behavior, drive loading, and tape operations.

This article explains how to determine whether running a filesystem cleaning operation on a Data Domain system will reclaim usable space. Cleaning removes physical storage consumed by deleted data that is not being referenced and has not yet been reclaimed by the system.

Data Domain (DD) displays a critical alert indicating that a tier of storage is unavailable - for example, "The Active tier is unavailable."

This article explains how to determine whether a "Power supply has failed" alert on a Data Domain Head Unit is valid or a false positive. It also provides steps to clear persistent indictments and verify Power Supply Unit (PSU) status.

The Support Channel determines how a Data Domain system delivers Autosupports, alert summaries, and real‑time alerts to Dell Support. By default, delivery is over email (SMTP). This article helps you diagnose and fix Autosupport delivery failures when using email.

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.

本文对 DD 系列平台中每个受支持的 DDOS 版本的推荐 BIOS 和 iDRAC 固件版本进行了逐个型号的清晰细分。它旨在帮助您快速确认哪些固件级别与您系统的 DDOS 版本保持一致，减少兼容性问题，并确保您的环境保持稳定、安全和完全受支持。使用下表，在几秒钟内查找适合您的特定 DD 型号的正确 BIOS 和 iDRAC 版本。
