Data Domain Operating System (DD OS) Physical Capacity Measurement (PCM) or Physical Capacity Reporting (PCR) Frequently Asked Questions (FAQ)

The boost file system on the Linux and Windows client behaves unexpectedly when Security Scanner or Security Applications scans or accesses files inside a Boost file system mount point.

This article describes how to identify and resolve network‑card-related errors reported in kern.info, bios.log, and system logs on Data Domain systems. These errors commonly involve transmit queue timeouts, unsupported modules, hardware faults, and firmware-related issues across Broadcom, QLogic, and Intel NICs.

Data Domain devices change status to "suspect" and a few minutes later, back to "normal."

CIFS share may become unavailable after being available for a while.

Oracle Incremental Merge (OIM) backups generate the message "Unable to query the list of archive logs for applying retention."

Unable to delete Retention Lock Governance mtree despite it appearing empty.

This article describes the steps to set and change the passphrase on a Data Domain (DD) system.

This article provides a workaround for Avamar backup failures to Data Domain due to SSL encryption.

The goal of this knowledge base article is to address Data Domain capacity issues when used with NetWorker. It provides details of how to reclaim space from Data Domain devices, create detailed problem definitions, identify specific logs, and steps required to resolve the problem.

This article is intended to assist Support and NetWorker administrators triage and troubleshoot issues regarding Data Domain Cloud Tier operations.

Instructions on how to implement NetWorker with a Data Domain Cloud Tier solution. Data Domain Cloud Tier moves data from the Active Tier to low‑cost, high‑capacity object storage in public, private, or hybrid clouds for long‑term retention.

This article provides basic information about configuration of DD Boost with CommVault Application. This article also describes the prerequisites required for configuring DD Boost with CommVault and supported configuration/workflows with CommVault 11.30.x and 11.32.x software versions.

BoostFS is a regular process that the operating system stops when the system restarts or the user logs off, and BoostFS for Windows mounts do not survive without the process. To remount BoostFS mounts during system startup, add boostfs mount commands as part of a system startup script.

Data Domain (DD) running Operating System (OS) 8.3.x and later cannot enable “Share Data with CloudIQ”; Graphical User Interface (GUI) shows error “Registry key config_master.support.cyber_security doesn’t exist”. SupportAssist was fixed by creating a new access key and disabling directFailoverEnabled, but CloudIQ remained disabled (config_master.support.cloudiq_enabled=0).

This article describes an Avamar cloud tier policy error caused by misconfigured Data Domain cloud tier settings or a temporary Avamar issue.

This article explains why a Data Domain system may report an "Invalid SAS cable topology detected" alert after reboot or system changes.

This article describes the process for removing a Data Domain cloud tier unit.

This article explains why maintaining sufficient free space is critical for optimal performance on a Data Domain (DD) system. High utilization can cause performance degradation, cleaning delays, and in severe cases, a full system condition that requires lengthy recovery procedures.

This article serves to assist on issues encountered with failed DDOS login or access.

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.

This article is a resolution path for connectivity issues encountered on Data Domain Virtual Tape Library (VTL)

This article explains the causes and resolutions for errors that occur when completing SupportAssist configuration on Data Domain systems, including issues related to invalid Access Key/PIN and registration failures.

Small-file workloads increase metadata processing during cleaning, especially in the pre‑enumeration phase; this results in slower cleaning performance and inaccurate progress estimates. For reliable expectations, use past cleaning runtimes rather than the estimated time displayed in the UI.

This article provides steps to upload Autosupport logs by customers.
