Disk Library for mainframe

Утечка дескрипторов файлов в DLm VTE или приложении VTD приводит к тому, что открывается слишком много файлов, и Virtuent прекращает работу с лентами. В результате могут появляться сообщения об ошибках, подобные тем, которые представлены в следующем журнале Virtuent Console (VT) (которые также сохраняются в журнале /var/bti/log/btilog): DLm0839E: Unable to assess space for /tapelibX/FS_XX (scandir error): Too many open files DLm0034I: sudo: error while loading shared libraries: libselinux.so.1: cannot open shared object file: Error 24 DLm0261E: Device BB17 volume P10130 Unable to set short-term lock: Too many open files DLm0810E: Command failed: crc32 /opt/webconsole/backup_config/current.json: Too many open files DLm0647E: Internal Error in opening /etc/mtab: Too many open files DLm0810E: Command failed: btitool show paths port=1: Too many open files

Site planning and preparation are vital to a successful DLm deployment. Considerations include environmental variables, floor load-bearing capacities, bay positioning and power cabling and connectors.

This document describes the aspects of sizing, capacity and performance, which need to be considered when designing a DLm solution. Sizing for capacity takes into account the total amount of data that a customer plans on storing on the DLm. Sizing for performance considers the customer’s backup windows and RPOs. This paper provides guidelines for both aspects of the sizing exercise.

Describes how to install a SVR-I2U-R2312 server in a cabinet or rack. Also describes how to replace a disk drive assembly, a power supply module, and the entire server.

This document provides information about the physical and environmental requirements, floor placement, connectivity, and power requirements to plan the installation of DLm systems.

This guide provides information on the features, performance, and capacities of EMC Disk Library for mainframe (DLm). It also includes installation and configuration information that is required for ongoing operation. DLm provides IBM tape drive emulation to the z/OS mainframe utilizing disk storage arrays in place of physical tapes.
