About the NetBackup consistency check repair (NBCCR) utility

The NetBackup consistency check repair (NBCCR) utility is a command line tool that processes database-catalog repair actions. It automates the application of approved suggested repair actions. Veritas technical support analyzes the data that the NBCC utility collects, and site-specific configuration information. This analysis results in the generation of a suggested repair actions (SRA) file. Before NBCCR is run, Veritas technical support interacts with the customer to determine which repairs are needed. Undesirable repair actions are deleted or commented out of the SRA file. Each line of the SRA file contains one repair action that is paired with an associated parameter.

The NBCCR utility executes each repair action in several stages.

Table: Stages of repair

Stage

Name

Description

Stage 1

Data collection

NBCCR first collects the information that is required to perform a repair.

Stage 2

Repair qualification

Immediately before the suggested repair is applied, NBCCR verifies that the current status of the tape still qualifies for the requested repair. It recognizes that time has passed and the environment may have changed since the data was collected. If so, it reports in a history file that the repair is not qualified.

Stage 3

Repair

Finally, NBCCR performs up to three steps of repair for every repair entry in the SRA file. An element may be modified to enable the repair and steps may be necessary after the repair. If the repair fails during the repair operation, NBCCR tries to roll back the repair so that the corrective action does not introduce any new errors.

NBCCR resides in the following location:

UNIX

/usr/openv/netbackup/bin/support/NBCCR

Windows

install_path\NetBackup\bin\support\NBCCR.exe

NBCCR accepts one input file, creates two output files, and uses one temporary file.

Input file

NBCCR accepts as input the Suggested Repair Action (SRA) file named mastername_NBCCA_timestamptxt. Technical Support analyzes the NBCC support package and generates this file which is sent to the end-user. This file is placed in the following directory for NBCCR processing:

On UNIX: /usr/openv/netbackup/bin/support/input/nbccr/SRA

On Windows: install_path\NetBackup\bin\support\input\nbccr\SRA

Output files

NBCCR automatically creates a separate directory for each SRA file processed. The file name is based on the contents of the SRA file. The name of the directory is as follows:

On UNIX: /usr/openv/netbackup/bin/support/output/ nbccr/mastername_nbccr_timestamp

On Windows: install_path\NetBackup\bin\support\output\ nbccr\mastername_nbccr_timestamp.

After repair processing is complete, NBCCR relocates the SRA file to the same directory.

NBCCR also creates the following output files and places them in the same directory.

  • NBCCR creates NBCCR.History.txt, which is a history file of all the repair actions attempted.

  • NBCCR creates NBCCR.output.txt.

Temporary file

While it runs, the NBCCR utility uses KeepOnTruckin.txt, which appears in the same location as the output files described in this table.

To terminate NBCCR while it processes repairs, delete this file. This action causes NBCCR to complete the current repair, then shut down. Any other interruption causes undetermined results.

The following sample NBCCR.output.txt files show the results of two MContents repairs. One where all images were found on tape and one where one or more images were not found on the tape:

  • Example 1: NBCCR found all images on the tape. The MContents repair action is successful.

    MContents for ULT001 MediaServerExpireImagesNotOnTapeFlag  
      ExpireImagesNotOnTape flag not set 
      ULT001 MContents - All images in images catalog found on tape 
      MContents ULT001 status: Success
  • Example 2: NBCCR did not find one or more images on the tape. The MContents repair action was not performed.

    MContents for ULT000 MediaServerExpireImagesNotOnTapeFlag  
    ExpireImagesNotOnTape flag not set
