Administrator Guide

NOTE: The --files in the ost --show --file_history command represents replicated files that were processed via the
DMA optimized duplication operation. This command displays only up to the last 10 such files. The --name in the
ost --show --name command represents the OST container name.
NOTE: For more information about OST-related DR Series system CLI commands, see the Dell DR Series System
Command Line Reference Guide .
Understanding RDA with OST Plug-In Diagnostic Logs
You can collect diagnostic logs for supported DMAs with the RDA with OST plug-in.
NOTE: The directory location, C:\ProgramData, is considered to be a hidden directory on Windows-based systems.
However, you can copy and paste C:\ProgramData\Dell\DR\log\ into your Internet Explorer Address bar or you can
enter this into the Windows command prompt window (Start→ All Programs→ Accessories→ Command Prompt).
For more information about RDA with OST plug-ins and logs, see the topics that follow.
Rotating RDA with OST Plug-In Logs for Windows
By default, the Windows log rotation size is set at 10 megabytes (MB). Once a log file has been reached this size, the
RDA with OST plug-in automatically renames the existing log file, libstspiDell.log to libstspiDell.log.old, and creates a
new log.
Modifying Log Rotation Size
To modify the log rotation size, you can edit the following registry key value:
HKLM\Software\Dell\OST\LogRotationSize
Immediately after modifying this value, the new rotation size value takes effect (meaning that you do not have to restart
the backup process).
Collecting Diagnostics Using a Linux Utility
You can use a Linux utility called Dell_diags to collect diagnostics from Linux-only clients. This Linux utility is installed by
the OST plug-in installer in the /opt/Dell directory. The tool collects the following types of information:
• var/log/libstspiDell.log.*
• usr/openv/netbackup/logs
• usr/openv/logs/nbemm/
• usr/openv/logs/nbrmms/
The Dell_diags diagnostics file is written to the following location: /var/log/diags_client location.
The following example shows the process for collecting the RDA with OST diagnostic logs (the root user account shown
represents one that resides on the media server, and is not to be confused with a root user account on the DR Series
system):
root@oca3400-74 ~]# ./Dell_diags –collect
Collecting diagnostics...Done
Diagnostics location: /var/log/diags_client//oca3400-74_2012-02-27_23-02-13.tgz
The default log level is set to Error in the OST plug-in, is user-configurable, and can be modified via the DR Series system
CLI or GUI.
