NetBackup Troubleshoot - Howto

This isn't really a how to, is a quick reference with some commands to use to debug the main problems that happens with NetBackup.


1. Log files
- NetBackup Logs
/usr/openv/netbackup/logs (Unix)
Install_path\NetBackup\logs (Win)
- Unified Logs
/usr/openv/logs (Unix)
Install_path\NetBackup\logs (Win)
- NetBackup Media Manager Logs
/usr/openv/volmgr/debug (Unix)
Install_path\volmgr\debug (win)

Obs.: Media manager Logs need be created.
Be aware with log level, they can increase an fill the directory (File system) and the NetBackup will stop to work.

2. Name Resolution
You need ensure that name resolution is working correctly, verify DNS and DNS reverse.

3. Commands you can use for day by day trouble shooting

- Command to list Process are runing
/usr/openv/netbackup/bin/bpps -x

- All process
/usr/openv/netbackup/bin/bpps -a

- List Jobs
/usr/openv/netbackup/bin/admincmd/bpdbjobs

- Command used to confirm the successful lookup of the client name
/usr/openv/netbackup/bin/bpclntcmd -hn client_name
/usr/openv/netbackup/bin/bpclntcmd -ip client_ip

- Commands used to expire or to calculate a new retention for a media
/usr/openv/netbackup/bin/bpexpdate -m ACB001 -d 0
- Change expiration of copy 2, does not afect copy 1
/usr/openv/netbackup/bin/bpexpdate -backupid eel_0904219764 -d 12/20/2010 08:00:00
-copy 2
- If bpxpdate don't work to expire the media execute the command before use bpexpdate
/usr/openv/volmgr/bin/vmquery -deassignbyid media_ID pool_number stat
- To check pool_number and stat
/usr/openv/volmgr/bin/vmquery -m media_ID

- Command to list configured Storage Units
/usr/openv/netbackup/bin/admincmd/bpstulist -L

- Command to list configured Policies
/usr/openv/netbackup/bin/admincmd/bppllist policy_name -L

- Command used to perform operator functions on drives
/usr/openv/volmgr/bin/vmoprcmd

- Command used to display media status
/usr/openv/netbackup/bin/admincmd/bpmedialist -rl 1

- Script to make a media report
/usr/openv/netbackup/bin/goodies/available_media

- Command to unfreeze medias
/usr/openv/netbackup/bin/admincmd/bpmedia -unfreeze -m ACB001

- Text interactive menu to administrate NetBackup when you can't access the GUI.
/usr/openv/netbackup/bin/bpadm

- Command to report media contents of a robotic library
/usr/openv/volmgr/bin/vmcheckxxx -rt tld -rn 1 -list

- Command to inventory a robotic library
/usr/openv/volmgr/bin/vmupdate -rt tld -rn 1 -full [-interactive] -use_barcode_rules

- Command to manager EMM server - bee careful using this command
/usr/openv/netbackup/bin/admincmd/nbemmcmd
This command can be used to list servers, medias, include new servers see nbemmcmd (1M)

- To delete a media manger
nbemmcmd -deletehost -machinename media_server -machinetype media

- To delete a tape
nbemmcmd -deletemedia -mediaid ABC001 -originhost server

- To tell you if which boxes are have a emmserver and if they are reachable
nbemmcmd -getemmserver

- Will let you know if there are any media conflicts
nbemmcmd -listmedia -conflicts

- Will let you know what hosts are seen as media_managers and master servers
nbemmcmd -listhosts

4. Sybase trouble shooting
- Database Files
/usr/openv/db/data (Unix)
Install_path\NetBackupDB\data (Windows)

- Binary Files
/usr/openv/db/bin (Unix)
Install_path\NetBackup\bin (win)

- To create a blank DBDB database for the recovery
http://seer.entsupport.symantec.com/docs/284299.htm

- Database Administration tool (since NetBackup 6.5.2)
/usr/openv/db/bin/dbadm (Unix)
\Veritas\NetBackup\bin\bpadm (Win)

Be careful to use this tool, some operations can stop and destroy database.

5. NetBackup Consistency Check (NBCC) utility
The NBCC command executes the NBCC utility that is used to confirm the integrity of portions of the NetBackup catalog related to tape media. This check includes the review of configured storage units, 5.x volume database hosts, 6.xEMMservers, tape media, and images associated with tape media.
If NBCC detects catalog inconsistencies, it generates a set of output files. It can create a support package bundle of these files by using available system utilities.
More information about the NBCC utility is available in the Using NetBackup Utilities section of the NetBackup Troubleshooting Guide.
