This article provides information about the patch release updates to the Dell PowerProtect Data Domain Operating System (DDOS), PowerProtect Data Domain Virtual Edition, PowerProtect Data Domain Management Center (DDMC), DD BoostFS, and DD Boost OpenStorage for Release 8.6.1.x.

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.

Commvault backups stall with errors 'Cannot set file access time' and 'Cannot mark file' when Data Domain retention lock is enabled.

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.

This article describes how to troubleshoot memory-related alerts on Dell Data Domain systems, including how to identify a faulty DIMM that requires replacement. It covers common alert codes, root causes of correctable and uncorrectable ECC errors, and step-by-step resolution guidance such as initiating POST-Package Repair (PPR), running diagnostic CLI commands, and performing physical troubleshooting.

Token-based authentication in DD Boost OST Plug-in 8.4 provides a more reliable authentication method and helps avoid intermittent credential decryption issues seen with earlier authentication handling in some NetBackup 10.x environments. It also improves credential security by eliminating dependence on encrypted password decryption workflows.

MarkLogic can be used with the Data Domain BoostFS plug-in; however, MarkLogic is not currently listed in the supported BoostFS application compatibility matrix and its POSIX compliance has not been qualified. Users requiring supportability confirmation should work with their Service Account Manager (SAM) to initiate a Request for Product Qualification (RPQ) and review the compatibility guide regularly for updates.

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

The GUI becomes unresponsive and RPM uploads fail because the iDRAC does not supply Secure Boot entries in host_bios.json, causing the sms_system_get_secure_boot API to error.

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

This 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.

This article describes how to use the Support Connectivity CLI command family to register, configure, monitor, and manage SupportAssist connectivity.

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.

A bonded interface speed mismatch alert may occur when one member interface negotiates at a lower speed than the other member interfaces in the bond. This causes the alert to remain active until all interfaces operate at the same speed.

This article explains how to generate a fresh autosupport (ASUP) log on PowerProtect DD, download it via the System Manager UI, and upload it for drive failure verification.

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).

Data Domain Virtual Edition (DDVE) reboots every hour.

Direct connect is a network topology where two Data Domain, PowerProtect Data Domain, IDPA, or other data protection systems are connected directly through dedicated interfaces without an intermediate switch or router. This article explains direct-connect networking requirements, common deployment scenarios, known issues, and troubleshooting methods for connectivity, routing, performance, and interface-related failures.

During a DDBoostFS upgrade on Linux, warning or informational messages may be displayed related to RPM signature verification, configuration file preservation, operating system libraries, or Lockbox migration status. If the upgrade completes successfully and BoostFS mount, read/write operations, and Lockbox authentication function normally, these messages do not indicate a BoostFS upgrade failure.

Data Domain systems support Active Directory Kerberos authentication and are transitioning away from legacy encryption methods. Starting with DDOS 8.8 and future supported releases, Kerberos communications with Active Directory will use only AES128 and AES256 encryption, removing support for weaker ciphers such as RC4 and DES while maintaining normal CIFS share functionality.

Active Tier in Object Store (ATOS) DDVE file system may go down with an alert about being unable to communicate with cloud provider metadata server.

Dell PowerProtect Data Domain remediation is available for multiple security vulnerabilities that could be exploited by malicious users to compromise the affected system.

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.
