Data Domain 容量解决方案路径。

Following a DD OS upgrade and reboot, certain network interfaces may not initialize successfully, resulting in missing routing rules and network connectivity issues. This behavior has been observed on systems using Intel E810 network adapters with Direct Attach (DA) passive cables and is resolved in DD OS 8.3.1.40 and later releases.

Network interfaces may go down, become intermittent, or fail to recover properly following events such as node reboots, HA failovers, link renegotiation, or other network transitions on systems equipped with Intel NICs. This issue can occur when the Intel workaround for M14MK dual-rate 10Gb/25Gb transceivers remains configured after the interfaces have been migrated to 25Gb-only transceivers. The resulting speed mismatch can cause interface connectivity loss and intermittent network behavior.

This article provides instructions for Customers, Partners, and Internal users to update Data Domain License File Formats (from ".lic" to ".xml" or from ".xml" to ".lic") for license compatibility with the DD OS Version.

Network Adapters with RDMA enabled that are installed outside of Slot 7 are causing issues during HA Mirroring Checks for NVRAM status. This is causing HA status to report as degraded with "NVRAM not ok" even though NVRAM is healthy.

Editing a Data Domain in Avamar fails with errors such as "Imported host certificate already exists for application(s): ddboost" because legacy certificate files remain in the ddboost certificate directory, causing the import process to abort.

Avamar is unable to remove the imported-ca for login-auth during certificate renewal due to changes in certificate ownership within the Data Domain. This can cause failure within GOAV when sync'ing updated certificates to Data Domain

This article provides instructions for performing a flea drain (legacy BMC reset) on Dell PowerEdge-based PowerProtect Data Domain appliances. This procedure can help resolve various system issues without requiring physical intervention.

HA pair with Retention Lock Compliance Enabled shows degraded status with SMS mirroring failing; logs contain iDRAC HTTP 500 “Failed to fetch iDRAC users, unable to update privilege”. The cause is an iDRAC stability issue that prevents user enumeration, leading HA to mark SMS as failed.

Both Data Domain (DD) (physical and virtual) and PowerProtect DD Management Center (DDMC) installs come with a REST service embedded. Customers may use it to build their own applications to interact with the DDs and DDMCs.

This article describes a condition where the Data Domain filesystem fails to start due to a potential Non-Volatile Random Access Memory (NVRAM) mismatch. It also provides a validated workaround to restore filesystem availability.

升级到 DDOS 8.5 或更高版本后，SupportAssist 配置可能会失败，并显示错误“无法加载 JSON 解析器”。

本文的主要重点是对单个接口关闭、多个接口关闭、接口连接时断时续和网卡损坏进行故障处理。更换部件应该是解决接口关闭问题的最后一步。先对查看交换机端之类的问题进行故障处理，有可能会最快解决问题。

Data Domain system gives a pre-check alert for licenses going deprecated.

STIG Compliance – STIG Requirement SV-279028r1138077: This requirement states that information transfer mechanisms must uniquely identify and authenticate source systems before permitting data access. To align with this requirement, DD Boost global-authentication-mode and global-encryption-strength should not be configured as none. Configure DD Boost to use two-way or two-way-password authentication and medium or high encryption strength, and verify that connected DD Boost clients such as PPDM support the selected settings.

本文提供结构化的故障处理工作流、特定于事件的修正指导以及 SDPM （NVRAM） 事件的最可能解决方法。

由于集成 DDBoost D4 库的初始化，BoostFS 装载操作可能会创建 /tmp/Boost_D4_Event.log文件。在受影响的版本上，可以使用全球可写权限创建文件;此行为已在以后的 BoostFS 版本中得到纠正，这些版本应用更严格的权限并在安装或升级期间自动更新现有文件。

本文通过提供域加入、OU 放置、身份验证配置、域验证、访问管理、CIFS 共享注意事项和高级故障处理的常用 CLI 命令，扩展了 Dell Data Domain 系统的 Active Directory 集成。它充当主要 Active Directory 指南的命令参考配套文件，包括用于验证和维护 Active Directory 连接的示例和最佳做法。

本文介绍如何在 BIOS 中清理和重新配置软件定义的永久性内存 （SDPM） 设置，并在系统返回 DDOS 后验证初始化是否成功。

本文解答了关于 Data Domain 许可的常见问题，内容涵盖电子许可 (ELMS)、许可证管理以及如何使用 Software License Central 进行部署。

当源 MTree 和目标 MTree 具有不匹配的保留锁定状态时，复制重新同步可能会失败，并显示错误“MREPL ASSOC 故障：目标 MTree 为 WORM，源请求删除 WORM （5312）”。仅当两个 MTree 都具有匹配的 Data Domain Retention Lock Governance 或 Compliance 设置时，才支持重新同步操作。

If the license is in the old format when upgrading a Data Domain controller to a new model, it fails on newer DDOS codes.

Step-by-Step Instructions on how to download a Data Domain Operating System (DDOS) Upgrade Release Package Manager (RPM), upload it to the server, and verify it was a successful download, before a planned DDOS upgrade with Remote Proactive.

This KB article outlines comprehensive guidelines for preparing a Data Domain High Availability (DDHA) system upgrade. Adhering to these instructions guarantees a successful upgrade experience.

Attempting to add a second disk pack to the active tier returns an error stating a partial shelf must be fully used first. The failure is caused by an insufficient capacity license that leaves the initial shelf only partially consumed.

由于在初始配置期间，无效的 MTU 配置被拒绝，但仍保留在注册表中，导致当系统稍后在接口初始化期间尝试应用无效 MTU 时，导致接口出现故障，因此 VLAN 接口在重新启动后变得无法访问。

本文提供当前 PowerProtect Data Domain 操作系统 （DDOS） 版本的下载链接和状态信息，包括功能和长期支持 （LTS） 版本。它还概述了升级注意事项、文档参考和支持的平台。

将 .lic 许可证文件应用于 Data Domain 系统时，该操作失败，因为系统需要 XML 格式的许可证文件。
