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 how to convert collection replication to mtree replication using the CLI.

A static route allows the administrator to specify the network interface (NIC) through which network traffic is directed to a target. This article talks about how to add the net and host route using a specific gateway and interface on Data Domain.

This article provides step-by-step instructions and directions for Customers, Partners, and Internal users for processing License Activation for the PowerProtect Data Domain Appliances from the Dell Digital Locker (DDL) and Software Licensing Central (SLC).

An alert on a Data Domain system shows a disk with only one active SAS path instead of two, indicating a Multipath (MPATH) issue.

NetWorker Clone Controlled Replication (CCR) fails, reporting Data Domain error code 5009 (I/O Error).

Data Protection Advisor (DPA) reports the cloud tier as having an unknown status due to Data Domain cloud units not being connected.

Adding a Data Domain host to Data Protection Advisor (DPA) may generate an error. Error: collector on 3741 fails because host down or credentials invalid, misconfigured Simple Network Management Protocol (SNMP) community string credentials.

This article describes Long-Term Retention (LTR) basic concepts, configuration, and frequently asked questions (FAQ) relating to LTR functionality.

Data Protection Advisor (DPA) fails to retrieve occupancy data for the Data Domain MTree capacity statistics report, yielding no results because the Physical Capacity Secure Shell (SSH) request is not configured.

Log in Using CAC or PIV Smart Card and User Certificates

This article helps with troubleshooting possible cable connection issues on SAS links to attached storage shelves and enclosures.

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.

Disks may show “Unknown” when a new drive isn’t recognized, a failed or unreliable drive reports unknown, a newly added enclosure isn’t integrated, or a replacement disk isn’t initialized.

This article outlines the steps required to resolve a disk that is in an absent state on a Dell Data Domain system.

This article explains the cause of the autosupport alert indicating that a disk has triggered continuous discovery, resulting in the enclosure slot being disabled. It also provides the required steps to replace the drive and reenable the slot.

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.

Descriptions of the various states that a disk drive on a Data Domain system can be in, and the significance of the state.

This article explains why disks appear in a Foreign state on Data Domain systems and provides the required steps to resolve the condition without risking data loss.

This article explains why a disk may appear in a "known" state on a Data Domain system and provides steps to diagnose and resolve the condition.

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.

With the introduction of Data Domain File System (DDFS) support for NTFS Access Control Lists (ACLs), it is necessary to use the Windows method for changing file and directory ownership and permissions.
