Create a new Virtual Local Area Network (VLAN) interface from either a physical interface or a bonded interface. An IP alias assigns an additional IP address to a physical interface, a bonded interface, or a VLAN.

DD HA node rebooted after panic or issue; failover occurred but interconnect and veth alias interface did not come up on alternate node.

This Knowledge Base article explains the limitations of CIFS share support on Data Domain systems regarding non windows clients.

Process overview for Data Domain Operation System (DDOS) upgrades on Data Domain "Highly Available" (DDHA) appliances.

Alert for space exceeding 90% will post even if 'critical-space-usage' is set to greater than 90%. This is expected behavior.

This article describes the steps to set and change the passphrase on a Data Domain (DD) system.

This article provides instructions for collecting a PowerProtect DD Management Center (DDMC) support bundle in versions 2.0.1.0 and higher.

The organization’s security team requires disabling password-based logins, which may include Active Directory integration and users using PIV cards.

Cleaning too often can cause fragmentation (poor locality), which negatively affects performance in all areas.

A support bundle (SUB) is a compressed archive of various log and configuration files from a Data Domain (DD). DD support and engineering use its contents when investigating issues. As a result, support agents are likely to ask for a SUB while working a support case. This article describes various methods to generate and collect a SUB and upload it for review.

This article describes how to resolve the condition where a disk drive is in a failed, absent, or powered off state.

Due to a software issue within DDOS (8.3.0.0), a daily disk failure is reported on external storage attached to systems running Protection Pool RAID (e.g DD6400)

A NetWorker VMware Protection (NVP) Virtual Machine (VM) File Level Restore (FLR) fails to mount. Instant Access restore may also fail. The error logging returns that the vProxy failed to log in in to the Data Domain because the REST service on the Data Domain is disabled.

Cloud tier cleaning will not start a quota limit that the ECS admin controls has been reached

Failover bonding on Data Domain relies on link state. If a NIC fails without link change, failover will not occur, causing possible connectivity loss if no alternate interface exists.

This article provides frequently asked questions and solutions for a DDOS upgrade.

NetBackup restores failing due to a changed SIZE_DATA_BUFFERS_DISK to 1048576 (1MB) (or a value that is similar)

To provide the air-gap feature of Cyber Recovery (CR), it ups and downs replication interfaces on Data Domain. There is a timing issue, with bonded interface configuration, that results in link status down being reported.

Interface groups can be used to control the interfaces used for DD Boost MFR, to direct the replication connection over a specific network, and to use multiple network interfaces with high bandwidth and reliability for failover conditions. All protection system IP types are supported—IPv4 or IPv6, Alias IP/VLAN IP, and LACP/failover aggregation.

Introduced in DDOS 7.5 and DDMC in 7.11, multifactor authentication adds an extra layer of security on the protection system. It requires the security officer and system administrator to enter an RSA SecurID passcode before certain destructive commands or configuration changes are allowed. The Multifactor Authentication panel allows the user to configure, enable, and disable multifactor authentication.

Data Domain - /data/col1/backup MTree is the default MTree that has been created for backward compatibility to older DDOS versions and is not allowed to be deleted.

When using failover bonding, the standby interface has many dropped packets. This is expected since the standby interface is not active.

DDOS can diagnose authentication issues for Active Directory from within the DD System Manager interface.
