basically Symantec has three tools in the toolset: NBCC (NBU configuration data collector), NBCCA (analysis tool) and NBCCR (repair tool).
NBCC and NBCCR are available to end users from 6.5.4 onwards, and analysis component is only available to Symantec engineers.
They will use NBCC/NBCCR in case of catalog inconsistencies.
Formal answer from the Veritas NetBackup 6.5.4 Documentation Updates
– run the NetBackup Consistency Check Repair (NBCCR) utility that repairs NBU database inconsistencies.
NBCCR [-passid passid] [-datapath path] [-volumedatabasehost volDB_host] [-h] [-versionhistory] [-v]
On UNIX and Linux systems, is /usr/openv/netbackup/bin/support/
On Windows systems, is \NetBackup\bin\support\
The NBCCR command executes the NBCCR utility that is used to apply the repair actions that are related to tape. The repair actions are contained in a Suggested Repair Actions (SRA) file. This utility executes NetBackup commands to perform these repairs. Symantec Tech Support generates the SRA file based on an analysis of data that the NBCC command collects. The NBCCR command should be run only at the direction of Symantec Technical Support. It should be used only to apply repairs in an SRA file generated by Symantec Technical Support. The NBCCR command creates a history file that contains the results of each repair action attempted.
The following events can cause inconsistencies: improper use of command-line commands, attempts to restore corrupted data, or by improperly decommissioninga media server. A full file system can also cause inconsistencies. More information about the NBCCR utility is available in the Using NetBackup Utilities section of the NetBackup Troubleshooting Guide pathnameSpecifies the full path or relative path of the directory that contains the repair actions file and the history file (default file names NBCCA.SRA.txt and NBCCA.history.txt). The default is the current directory. Do not include a trailing "/" or "\" character in the pathname.
-emmpw password Specifies the name of the EMM password if different than the default password.
Outputs the extended help information and exits.
-passid password Specifies a string (no embedded spaces allowed) that is prepended to the default input and output file names. The default is the null string, the default repair action file name is NBCCA.SRA.txt, and the default history file name is NBCCR.history.txt.
-sra filename Specifies the suggested repair action (SRA) file name. The default name is NBCCA.SRA.txt.
Specifies the verbose mode. A verbose version of the help is output if you use the -v option with the -h option.
Prints the version of the NBCCR utility and exits.
