Data Domain Boost – File System

This document highlights minimum, recommended, and latest code versions for Dell Technologies Enterprise and Datacenter Infrastructure products. We carefully evaluate and monitor code deployment data to ensure that product releases meet our stringent expectations to provide our customers with reliable products and solutions.

This article explains the cause and resolution of alerts related to the Baseboard Management Controller (BMC), also known as iDRAC on Dell PowerEdge-based platforms. The BMC is an embedded controller that monitors system health parameters such as temperature, fan speeds, power status, and voltage. When the BMC becomes unresponsive or fails, the Data Domain system generates an alert.

Data Domain generates Serial Attached SCSI (SAS) or Multipath (MPATH) alerts when a link fails; missing connections, loss of redundancy, caused by incorrect or loose cabling or hardware faults.

This article provides an understanding of the Data Domain Disk Reconstruction process.

Unable to create DD device with DD Retention Lock enabled due to expired Management certificate in NSR Data Domain resource file.

On DD3300 and DP4400, disks flagged by the PowerEdge RAID Controller or iDRAC generate EVT‑STORAGE‑00031 (hardware fault) or EVT‑STORAGE‑00032 (recoverable predictive failure) alerts.

Summary: This document provides actions that Tech Support would complete when performing a general health check on a Data Domain (DD) System. It includes general commands and outputs to help identify alerts or misconfigurations.

Because NFS clients are increasingly using NFSv4.x as the default NFS protocol level, protection systems can now employ NFSv4 instead of requiring the client to work in a backwards-compatibility mode. Clients can work in mixed environments in which NFSv4 and NFSv3 must be able to access the same NFS exports. The DDOS NFS server can be configured to support NFSv4 and NFSv3, depending on-site requirements. You can make each NFS export available to only NFSv4 clients, only NFSv3 clients, or both.

This article discusses a "net set up flag failure when an interface is enabled.

Following a DDOS upgrade some systems might report a firmware mismatch.

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

Too many connections error is the result of lots of connections being created and opened but never closed and terminated. This is causing the active connections count to increase until 256 which is the maximum limit of active connections. The new connections being opened later are failing with too many connections error.

Cloning failed for all VMware save sets, when Retention Lock (RL)is enabled on mtree. System and Database cloning is successful, only VMware save sets are affected. VMware cloning works successfully, and fails immediately when RL is enabled. No other changes are done.

This article contains limitations and recommendations for Data Domain with regard to Veeam 12 backup and replication user guide and other documents.

This article discusses how to use tThe Realtime Charts panel which displays up to seven charts that show real-time subsystem performance statistics, such as CPU usage and disk traffic.

This article explains how to disable the SNMP Agent in iDRAC for DD3300, DD6400, DD6900, DD9400, and DD9900 systems.

NetWorker fails to mount ddboost device with error 5044 read-only file system.

This document serves to help with identifying the error or and fault and provide a resolution path.

The Cyber Recovery software enables and disables the replication Ethernet interface and the replication context on the Data Domain in the Cyber Recovery environment.

For environments that are not using a VPN for secure connections between sites, Data Domain Replicator software can securely encapsulate its replication payload over SSL with AES 256-bit encryption for secure transmission. This process is also known as encrypting data in flight. You can encrypt the data replication stream by enabling the Data Domain Boost file replication encryption option.

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

This article provides information about the Replication Version Compatibility Matrix. It provides information about supported replication (MTree, directory, collection, and delta) for different configurations per Data Domain operating system versions.

The hardening process is twofold. Traditionally, customers that are looking to harden a system are doing so because they are either under mandate, or are practicing secure computing practices. These tables provide both the hardening procedures and the mitigation steps to comply with federal Defense Information Systems Agency (DISA) Security Technical Implementation UIdes (STIGs) on the device. The information in this guide is related to our latest DDOS release 7.10.

This article provides steps for troubleshooting Avamar backup failures to Data Domain.

NFSv4 backups fail when there are more than the maximum limit of 8000 simultaneous NFSv4 connections.

BoostFS Panics or Crashes or the mount point becomes unresponsive when the Backup Application performs I/O operations on the BoostFS mount point.

The failure of NetBackup Auto Image Replication (AIR) jobs can occur when the same storage unit is used as both the source and destination in the AIR topology.

A host certificate allows DD Boost client programs to verify the identity of the system when establishing a connection. CA certificates identify certificate authorities that the system should trust. The topics in this section describe how to manage host and CA certificates for DD Boost.

This article is created to provide commands on how to configure physical interfaces through command-line interface (CLI) on the Data Domain.

Configure the management interface during initial system setup before configuring the interfaces for user traffic. You must configure at least one physical interface before the system can connect to a network.
