Database App Agent

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.

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.

There are circumstances where we would want to backup the historical database on a DD.

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).

How to review the NetWorker environment and Data Domain (DD) capacity when the DD space consumption is growing.

Is Data Domain affected by Microsoft KB5020805 (CVE-2022-37967), Microsoft KB5021130 (CVE-2022-38023), or Microsoft KB5021131 (CVE-2022-37966)

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.

PowerProtect Data Domain systems have reported being stuck in a reboot loop. The NVRAM driver fails to load or initialize successfully resulting in a system reboot.

A defect has been found in some recent DDOS versions (confirmed in 7.7.4, 7.9.0.10 and 7.10.0, dubious if affecting DDOS 7.7.3 as well) by which an FS process PANIC may occur in the inode cache code when, depending on the workload, a cache element pool runs out of memory for further allocations.

When a backup application is configured and integrated with DD Retention Lock (RL), certain backup application and DD RL configurations may lead, in some situations, to backup failures, one of which is described and resolved here. The logs in this KB are for Commvault used as the backup application, but the facts presented are equally applicable to any other backup software which supports DD RL

This article provides best practices and configuration guidelines for applications with the Data Domain DD Boost File System Plug-In (BoostFS). In addition, the article contains insights and tips on how the application should be configured to maximize all the benefits of BoostFS.

This article provides a general overview of how to collect the ddfs.info logs from a NetWorker system when troubleshooting NetWorker backup, clone, or recover operations.

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.

The NVRAM and its Battery Backup Unit (BBU) are critical components of the Data Domain Data Invulnerability Architecture. The Data Domain Operating System (DDOS) monitors these components. If a hardware fault occurs, DDOS generates an alert that must be addressed immediately to maintain system integrity.

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

Data Domain High Availability (HA) can experience drive failures during HA failover due to a known drive firmware issue. Some systems may experience the inability of the file system to startup after a failover or reboot.

This issue affects Data Domain models DD6400, DD6900, DD9400, and DD9900, with software releases 7.2.0.100, 7.7.3, and 7.9, where the power supply status is incorrectly displayed as AC lost due to a parsing error in the DDOS Hardware platform monitor service.

This article explains the cause and recommended action for alert ENVIRONMENT-00032, which indicates a failure in the storage processor on a Data Domain system. The alert generally indicates a hardware fault on the system motherboard.
