What's new in this release

What’s new in this release

This release includes new features, maintenance fixes, and enhancements for the DR Series system software. (Refer to the section, “Known Issues and their Resolutions,” for detailed information on maintenance fixes.)

The following list describes the new features and enhancements that are included in the 4.0 release.

•
New Graphical User Interface (GUI) — This release provides a new, enhanced GUI design that is optimized for PC and mobile platforms.
•
Platform release — This software release applies to all supported DR Series models/platforms.
•
New license format — This release provides licensing support for the new Quest license format with continued support for the original Dell license format.
•
Updated expansion shelf support — This release adds support for the 4TB drive - 36TB Dell MD1200 expansion shelf on the DR4100.
•
VTL replication — Replication of VTL type containers is now available.
•
Fiber channel (FC) support — FC support for VTL is now available on the DR4300 and DR6300 for the following Data Management Applications (DMA)s: NetVault Backup, NetBackup, Backup Exec, and CommVault.
 
NOTE: For FC, Multi-Path, Multi-Initiator and Persistent reservation are not currently supported. Single target port configuration only is supported for FC VTL in the DR Series system. This limitation will be removed in a future DR Series release.
•
Storage groups — You now have a new capability to organize your data by creating storage groups and creating containers within those storage groups on your DR Series system. A storage group allows you to create separate storage policies, for example, for different data groups and the different capacities utilized on a single DR Series system.
•
Secure Erase — Secure Erase is a process for securely deleting data that follows standards developed by the Defense Security Service (DSS). In the process of erasing, the system overwrites data with zeros, a random pattern of data, or ones (1s) to make the original contents unreadable.
•
Registration with Quest Support Portal — You can now register your DR Series system with the Quest Support Portal by using the DR Series system CLI system --support_agent set of commands. The registered DR Series system will collect certain information that it will transmit to Quest Support. Such information can include operational statistics, performance metrics, diagnostic information and configuration settings of the DR Series system. This enables support personnel to monitor and capture information to proactively help troubleshoot issues with your system. Refer to the DR Series System Command Line Reference Guide for details about the system --support_agent commands.

Issue

Description/Workaround

31252

After upgrading to 4.0, you may see a slight decrease in savings percentage on the next update; over time this savings will come back in line as the old data stream is aged out.

This issue is targeted to be fixed in our follow-on release 4.0.0.1. This issue can also result in a slight drop in RDA performance for the next backup but should return in the follow-on backup.

30895

Cleaner schedules that span multiple days are not retained upon upgrade to 4.0.

This issue is targeted to be fixed in our follow-on release 4.0.0.1. You can also work around this issue now by using the DR Series system command line interface (CLI). Please contact Quest Support if you want to fix this issue via the CLI.

31123

At end of upgrade, you see the alert: "SVDC reserved alert ##."

If you see this alert, the last part of the upgrade failed. Please contact Quest Support, or run the upgrade again.

30813

The OST Accelerator option (synthetic backups) can perform poorly under heavy load conditions.

While you can continue to use OST, disable the Accelerator option in these scenarios. This issue will be resolved in a future release.

30422

CIFS Administrator password migration from DR Series system software version 3.x to 4.x.

During the upgrade to version 4.0:

1.
Users corresponding to local workgroup users used for CIFS authentication will be created with the CIFS role and a default password (St0r@ge!).
2.
A Message will inform the users of the above and request him/her to set the password of these users to the password of the corresponding local workgroup accounts.
3.
For local workgroup accounts for which the migration has failed, a message will be displayed asking users to delete these accounts with "authenticate --delete" commands, and then create users with the CIFS role and appropriate CIFS authentication information manually.

CIFS traffic is showing up in the usage graphs when only running iSCSI.

This is a reporting issue only as each protocol uses a similar transport structure. You can ignore the CIFS traffic in this scenario.

29356

When upgrading from DR Series system software version 3.x to 4.0, the backup_user is migrated based on backup_user configuration in version 3.x. This is to minimize post-upgrade configuration.

Configuration 1 - When RDA and OST are configured in 3.x,, the backup_user password is reset to default during the 4.0 upgrade.

Configuration 2 - When only RDA is configured in 3.x, the backup_user password is set to RDA during 4.0 upgrade.

Configuration 3 - When only OST is configured in 3.x, the backup_user password is set to OST during 4.0 upgrade.

29255

GUI: After upgrading the DR Series system software from 3.0.0.2 to 4.0, DR Series members are not listed in the Global View page.

Only Global View member lists from software version 3.1 and later will be migrated.

GV Members which were added in 3.0.x.x builds should be added/re-entered manually after upgrading the DR to 4.0.

28547

Newly added tapes do not show up with "inventory robot" and "update volume config." In NetBackup, when trying to discover newly added tapes, they do not get discovered in the first attempt.

Rerun the tape inventory twice to discover add-on tapes.

27538

Secure connection error occurs in Firefox when navigating to the DR Series system page:

"Error code:

sec_error_reused_issuer_and_serial"

Delete your old certificate exception and use temporary exceptions for subsequent visits to the DR Series system page.

On Solaris, the standalone RDA package installation conflicts with existing packages.

If you are trying to upgrade the RDA plugin on Solaris, the command, pkgadd, will prompt for conflicting files. Respond ‘y’ for yes to the following prompts for installation to complete successfully.

Do you want to install these conflicting files [y,n,?,q] y Do you want to continue with the installation of <DellRDSPlugin-64bit> [y,n,?]y

RDNFS binary upgrade fails in RHEL 7 client.

Uninstall any existing RDNFS package and then install the new one.

23709

Changing the machine host name does not get updated properly in all components.

This issue does not cause known failures to the normal operation of the DR Series system and can be ignored. It will be fixed in a future release.

23641

Cannot join into domain by adding DR into multiple OUs

Work with technical support to add unit to multiple OUs using the authenticate command type as follows:--ou topLevelOU/middleLevelOU/LowerLevelOU/ TargetOU

20553

Specific umount options do not work for Rapid NFS.

The -l and -f options are not supported in the rdnfs unmount procedure.

Replication traffic that is configured to go through an assigned bond may still run through the default bond (bond0).

If you want to run replication traffic through another bond interface, contact Technical Support to update the route.

17294

A NetVault Backup data copy or duplication will stop if the DR Series system goes into maintenance mode as it moves into a read-only condition when this occurs.

Restart the datacopy operation after the DR Series system enters the operational mode.

17206

Advanced networking allows you to change the IP of an interface that is part of a replication link.

Understand your current configuration before adding new advanced networking configuration so that you do not impact the current system configuration.
