Product(s): NetBackup (8.3.0.1)

NetBackup MSDP log files

The NetBackup deduplication components write information to various log files. Some NetBackup commands or processes write messages to their own log files. Other processes use Other processes use Veritas Unified Logging (VxUL) log files. VxUL uses a standardized name and file format for log files. An originator ID (OID) identifies the process that writes the log messages.

See About legacy logging.

See About unified logging.

In VxUL logs, the messages that begin with an sts prefix relate to the interaction with the deduplication plug-in. Most interaction occurs on the NetBackup media servers. To view and manage VxUL log files, you must use NetBackup log commands. For information about how to use and manage logs on NetBackup servers, see the NetBackup Logging Reference Guide. The guide is available through the following URL:

http://www.veritas.com/docs/DOC5332

Most interaction occurs on the NetBackup media servers. Therefore, the log files on the media servers that you use for disk operations are of most interest.

Warning:

The higher the log level, the greater the affect on NetBackup performance. Use a log level of 5 (the highest) only when directed to do so by a Veritas representative. A log level of 5 is for troubleshooting only.

Specify the NetBackup log levels in the Logging host properties on the NetBackup master server. The log levels for some processes specific to certain options are set in configuration files as described in Table: Logs for NetBackup MSDP activity.

Table: Logs for NetBackup MSDP activity describes the log files for each component.

Table: Logs for NetBackup MSDP activity

Component	VxUL OID	Description
Backups and restores	117	The nbjm Job Manager.
Backups and restores	N/A	Messages appear in the log files for the following processes: The bpbrm backup and restore manager. The following is the path to the log files: UNIX: `/usr/openv/netbackup/logs/bpbrm` Windows: `install_path\Veritas\NetBackup\logs\bpbrm` The bpdbm database manager. The following is the path to the log files: UNIX: `/usr/openv/netbackup/logs/bpdbm` Windows: `install_path\Veritas\NetBackup\logs\bpdbm` The bptm tape manager for I/O operations. The following is the path to the log files: UNIX: `/usr/openv/netbackup/logs/bptm` Windows: `install_path\Veritas\NetBackup\logs\bptm`
Catalog shadow copies	N/A	The MSDP catalog shadow copy process writes messages to the following log files and directories: UNIX: /storage_path/log/spad/spad.log /storage_path/log/spad/sched_CatalogBackup.log /storage_path/log/spad/client_name/ Windows: storage_path\log\spad\spad.log storage_path\log\spad\sched_CatalogBackup.log storage_path\log\spad\client_name\
Client deduplication proxy plug-in	N/A	The client deduplication proxy plug-in on the media server runs under bptm, bpstsinfo, and bpbrm processes. Examine the log files for those processes for proxy plug-in activity. The strings proxy or ProxyServer embedded in the log messages identify proxy server activity. They write log files to the following directories: For bptm: UNIX: `/usr/openv/netbackup/logs/bptm` Windows: `install_path\Veritas\NetBackup\logs\bptm` For bpstsinfo: Windows: `/usr/openv/netbackup/logs/admin` UNIX: `/usr/openv/netbackup/logs/bpstsinfo` Windows: `install_path\Veritas\NetBackup\logs\admin` Windows: `install_path\Veritas\NetBackup\logs\stsinfo` For bpbrm: UNIX: `/usr/openv/netbackup/logs/bpbrm` Windows: `install_path\Veritas\NetBackup\logs\bpbrm`
Client deduplication proxy server	N/A	The deduplication proxy server nbostpxy on the client writes messages to files in the following directory, as follows: UNIX: `/usr/openv/netbackup/logs/nbostpxy` Windows: `install_path\Veritas\NetBackup\logs\nbostpxy`.
Deduplication configuration script	N/A	The following is the path name of the log file for the deduplication configuration script: UNIX: storage_path/log/pdde-config.log Windows: storage_path\log\pdde-config.log NetBackup creates this log file during the configuration process. If your configuration succeeded, you do not need to examine the log file. The only reason to look at the log file is if the configuration failed. If the configuration process fails after it creates and populates the storage directory, this log file identifies when the configuration failed.
Deduplication plug-in	N/A	The DEBUGLOG entry and the LOGLEVEL in the `pd.conf` file determine the log location and level for the deduplication plug-in. The following are the default locations for log files: UNIX: /var/log/puredisk/pdplugin.log Windows: C:\pdplugin.log You can configure the location and name of the log file and the logging level. To do so, edit the DEBUGLOG entry and the LOGLEVEL entry in the `pd.conf` file. See About the MSDP pd.conf configuration file. See Editing the MSDP pd.conf file.
Device configuration and monitoring	111	The nbemm process.
Device configuration and monitoring	178	The Disk Service Manager process that runs in the Enterprise Media Manager (EMM) process.
Device configuration and monitoring	202	The storage server interface process that runs in the Remote Manager and Monitor Service. RMMS runs on media servers.
Device configuration and monitoring	230	The Remote Disk Service Manager interface (RDSM) that runs in the Remote Manager and Monitor Service. RMMS runs on media servers.
drcontrol utility	N/A	You must run the drcontrol utility on the MSDP storage server host. The command requires administrator privileges. The utility creates a log file and displays its pathname in the command output. The utility writes log files to the following directory, depending on the operating system: UNIX: /[storage_path]/log/drcontrol/policy_admin */storage_path/log/drcontrol/dedupe_catalog_DR* Windows: storage_path\log\drcontrol\policy_admin storage_path\log\drcontrol\dedupe_catalog_DR See About protecting the MSDP catalog. See About recovering the MSDP catalog.
Installation	N/A	The NetBackup installation process writes information about the installation of the deduplication components to a log file in the following directory: UNIX: /var/log/puredisk Windows: %ALLUSERSPROFILE%\Symantec\NetBackup\InstallLogs
NetBackup Deduplication Engine	N/A	The NetBackup Deduplication Engine writes several log files, as follows: Log files in the storage_path/log/spoold directory, as follows: The spoold.log file is the main log file The storaged.log file is for queue processing. A log file for each connection to the engine is stored in a directory in the storage path spoold directory. The following describes the pathname to a log file for a connection: hostname/application/TaskName/MMDDYY.log For example, the following is an example of a crcontrol connection log pathname on a Linux system: `/storage_path/log/spoold/server.example.com/crcontrol/Control/010112.log` Usually, the only reason to examine these connection log files is if a Veritas support representative asks you to. A VxUL log file for the events and errors that NetBackup receives from polling. The originator ID for the deduplication engine is 364.
NetBackup Deduplication Engine	364	The NetBackup Deduplication Engine that runs on the deduplication storage server.
NetBackup Deduplication Manager	N/A	The log files are in the */storage_path/log/spad* directory, as follows: `spad.log` `sched_QueueProcess.log` `SchedClass.log` A log file for each connection to the manager is stored in a directory in the storage path spad directory. The following describes the pathname to a log file for a connection: hostname/application/TaskName/MMDDYY.log For example, the following is an example of a bpstsinfo connection log pathname on a Linux system: `/storage_path/log/spoold/server.example.com/bpstsinfo/spad/010112.log` Usually, the only reason to examine these connection log files is if a Veritas support representative asks you to. You can set the log level and retention period in the Change Storage Server dialog box Properties tab. See Changing MSDP storage server properties.
Optimized duplication and replication	N/A	For optimized duplication and Auto Image Replication, The following are the log files that provide information: The NetBackup bptm tape manager for I/O operations. The following is the path to the log files: UNIX: `/usr/openv/netbackup/logs/bptm` Windows: `install_path\Veritas\NetBackup\logs\bptm` The following is the path name of MSDP replication log file: `/storage_path/log/spad/replication.log`
Resilient network connections	387	The Remote Network Transport Service (nbrntd) manages resilient network connection sockets. It runs on the master server, on media servers, and on clients. Use the VxUL originator ID 387 to view information about the socket connections that NetBackup uses. Note: If multiple backup streams run concurrently, the Remote Network Transport Service writes a large amount of information to the log files. In such a scenario, Veritas recommends that you set the logging level for OID 387 to 2 or less. To configure unified logs, see the following guide: The NetBackup Logging Reference Guide: http://www.veritas.com/docs/DOC5332
Resilient network connections	N/A	The deduplication plug-in logs information about keeping the connection alive. For more information about the deduplication plug-in log file, see "Deduplication plug-in" in this table. The `pd.conf` file FILE_KEEP_ALIVE_INTERVAL parameter controls the connection keep alive interval. See About the MSDP pd.conf configuration file. See Editing the MSDP pd.conf file.
