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.

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 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.

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.

Steps to determine why Data Domain (DD) cleaning is taking longer than expected.

This article is provided to diagnose and resolve slow cleaning issues caused by a replication context with lag.

This article provides instructions to resolve CPU misconfiguration alerts on Dell EMC PowerProtect DD9900, DD9910, and DD9410 appliances. These alerts occur when hyperthreading settings do not match platform requirements.

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.

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.
