Data Domain Capacity Resolution Path.

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) cables and is resolved in DD OS 8.3.1.40 and later releases.

A BoostFS mount operation may create the /tmp/Boost_D4_Event.log file due to initialization of integrated DDBoost D4 libraries. On affected releases, the file may be created with world-writable permissions; this behavior has been corrected in later BoostFS releases that apply more restrictive permissions and automatically update existing files during installation or upgrade.

This article expands on Active Directory integration for Dell Data Domain systems by providing commonly used CLI commands for domain joins, OU placement, authentication configuration, domain verification, access management, CIFS share considerations, and advanced troubleshooting. It serves as a command-reference companion to the primary Active Directory guide and includes examples and best practices for validating and maintaining Active Directory connectivity.

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 transceivers remains configured after the interfaces have been migrated to W4GPP 25Gb transceivers. The resulting speed mismatch can cause interface connectivity loss and intermittent network behavior.

This article provides a structured troubleshooting workflow, event-specific remediation guidance, and the most likely resolution for SDPM (NVRAM) events.

This article describes how to sanitize and reconfigure Software Defined Persistent Memory (SDPM) settings in the BIOS and verify successful initialization after the system returns to DDOS.

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

MTree replication resync can fail with error "MREPL ASSOC failed: Dest MTree is WORM, source requests removal of WORM (5312)" when the source and destination MTrees have mismatched Retention Lock states. Resync operations are only supported when both MTrees have matching Data Domain Retention Lock Governance or Compliance settings.

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.

A VLAN interface became inaccessible after a reboot because an invalid MTU configuration was rejected during initial configuration but still persisted in the registry, causing the interface to fail when the system later attempted to apply the invalid MTU during interface initialization.

KB explains a possible reason why an on-premise DDVE running off VMware may be seen to reboot every few minutes with leaving no traces or logs in the DDOS

Migration send may fail with active critical alerts when the destination hostname specified in the migration command does not match the destination hostname defined in the replication context. Ensure the hostname used in the migration send command matches the destination system hostname configured in the replication context.

A Dell Data Domain DD6400/6410 system may intermittently generate false "EVT-STORAGE-00039: RAID reconstruction is in progress" alerts even though no disk failures, disk errors, or active RAID rebuilds exist.

A Data Domain (DD) system generates alert EVT-ENVIRONMENT-00029 with the message "I/O module has failed" when a PCIe I/O module (also known as a SLIC or PCI card) fails or is removed. Affected card types include SAS, NIC, NVRAM, and Fibre Channel (FC).

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.

Summary: DDOS precheck fails because of an old certificate in the trust chain.

When applying a .lic license file to a Data Domain system, the operation fails because the system requires an XML-formatted license file.

Summary: This document details the steps to register/add a Data Domain System to Secure Connect Gateway while using connectemc.

Clear entries by removing PostgreSQL DB and reinstalling Avamar REST API rpm package.Troubleshoot backup failure by checking software version and client properties on NMC1.

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

Starting with DD OS 8.4, firmware-based LLDP is disabled by default on supported Intel NICs to prevent network stability issues affecting LACP, bonded interfaces, and HA communication. This change addresses multiple field-observed issues including transmit timeouts, intermittent connectivity, and heartbeat failures.

The primary focus for this article is to troubleshoot an interface down, multiple interfaces down, an intermittent interface, and a bad network card. Replacing parts should be the last step in resolving interface down issues. Troubleshooting these issues first such as reviewing the switch side, may lead to the quickest resolution.

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 identify and resolve memory-related errors on Dell Data Domain systems.

When using failover bonding, the standby interface has many dropped packets. This is expected since the standby interface is not active.

This article describes a specific circumstance where space reclamation may not proceed despite a lack of media database records for the files in question.

Data Domain systems initiate a graceful shutdown if multiple disk failures occur and RAID reconstruction cannot proceed. This protective measure prevents potential data loss when RAID protection reaches a critical state.
