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.

This article describes an issue in Data Domain Operating System (DDOS) version 7.8 that prevents downloading core dumps from the web interface.

AWS is changing their server certificates from S3 to certificates issued by Amazon Trust Services CA. This change impacts Data Domain systems that are configured with Cloud Tier and Data Domain Virtual Edition (DDVE) deployed on AWS Cloud platform with Active Tier on Object Storage (ATOS).

This article describes how to migrate AWS Elastic Block Store (EBS) volume from gp2 to gp3 type for Data Domain Virtual Edition (DDVE) appliance deployed in AWS cloud platform.

DDBMA: SQL Cluster Database Restore failing with 'disk resource containing the file is not present in the cluster group'.

Replicated period for log backups for SQL is showing the wrong retention period on the Destination side.

The /ddvar (also known as /ddr/var) filesystem is the primary location that DDOS uses to store logs. This knowledge base article describes the common causes and steps to take to help alleviate or free up space inside /ddvar

A few Backup applications using NFSV4 Client backups to Data Domain receive Remote I/O Errors. Clients cannot resolve the same error.

Some customers may rely on GUI Data management-->Mtree -->'Daily Written' numbers to check their backup size, this is not accurate when there is data-movement on the same mtree as the diagram may show both Active and Cloud tier injestions, hence both backup and data-movement would be counted in resulting to misleading number for backup alone statistics.

How to diagnose a failed or absent Trust Platform Module (TPM) on a Data Domain system.

Attempts to delete a mtree or DDBoost that is empty and the retention-lock (enabled or disabled) fails.

Data Domain: Increase TCP Window size to improve Backup & Restore performance.

Basic troubleshooting steps to investigate data movement failures or issues.

File systems created before DDOS 7.5.x may panic after upgrading to DDOS 7.10.x or later if mtree replication is configured. The panic message is "ddr/dm/dmbt_iface.c: dmbt_get_entry_inode: 19746: !(ret == DD_ERR_NONE)."

This article outlines the procedure for performing an offline firmware update on Aries-KP model drives (HUS72604CLAR3000 and HUS72604CLAR4000) from version N9C0 to NE70.

This article explains how to use the Goav dd check-ssl feature to resolve SSL connectivity issues between Avamar and Data Domain.

Data Domain: DDMC: Added DDs and DDVEs are not listed under Configure update section when using AD users

Data Domain Virtual Edition (DDVE) deployed in Microsoft Azure Cloud requires an operating disk, NVRAM disk, and as many metadata disks as necessary for storing backups. However, initially after deployment and with no storage manually added, a "System" disk appears which is not for DDVE, the operating system, or the NVRAM.

After upgrading DDOS, receive the error "Default authentication mode for DD Boost clients does not provide over-the-wire encryption."

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.

After upgrading the destination end for Collection Replication to DDOS 7.7.2 or later, the FS process fails to start. It becomes unresponsive with "PANIC: ddr/lib/dd_flashcache_common.c: dd_fc_set_size_params: 879: !(high_water_cnt < num_blks)"

The standby or passive node of a high availability (HA) pair does not report active tier unavailable, but the active node reports that HA is degraded.

When PowerProtect backups are created from the same PowerStore appliance, to the same PowerProtect DD system, but using different Storage Unit names and backup policies, only one of the backups are retrievable.

The Data Domain (DD6400) generates an alert, Environment alert code ENVIRONMENT-00049, due to an invalid hardware configuration caused by unsupported Qlogic Network Interface Cards (NICs).
