Dell recommends that if core_pattern on the client is set by NAT to a specific directory, then the diagnostics script has to look into that directory for any related cores.

NetBackup on Windows Media Servers

For NetBackup running on a Windows media server, Dell recommends gathering the following files:

If a server failure is involved (which could be an inapparent or silent failure), the Windows media server event log for the application could be collected by using Administrative Tools → Event Viewer. Next, check the Windows Logs → Application. Typically, the last entry marked with Error is the one for which you are searching.

Configuring and Using VTL

Configuring and Using VTL

This topic introduces Virtual Tape Libraries (VTLs) and related concepts and tasks. Refer to the subsequent topics and procedures in this section for more information.

Understanding VTL

Understanding VTL

A Virtual Tape Library (VTL) is an emulation of a physical tape library on a disk-based deduplication and compression system such as the DR Series system. The tape library is exposed to a Data Management Application (DMA) as if it is a physical library with tape drives and cartridges, which the application uses for backup. Because a VTL completely emulates a standard library, the introduction of virtual tape is seamless and transparent to existing tape backup/recovery applications. The management of the library, including the drives and tapes, is done by the DMA using SCSI commands. For details on the applications supported, see the Dell DR Series System Interoperability Guide.

Terminology

Terminology

This topic introduces and briefly defines some basic VTL terminology used throughout the DR Series system documentation.

Description

Library

A library is an emulation of a physical tape library and shares the same characteristics such as media changer, tape drives, and slots (cartridge slots).

Tape Drive

A Tape drive is a logical unit which is part of the emulated library. The media or cartridge is loaded in the Tape drives to be accessed by the Data Management application.

Tapes/Media/Cartridges

Tapes are represented as files and are units within the VTL where data is actually written. Tapes are loaded into a Tape Drive before being accessed.

Slots

Tapes are parked in Slots before they are retrieved by the data management application for access.
