Symptoms

The NetWorker server protection bootstrap save set fails with the following error message:

Bootstrap fails: 4746:save: external ASM `nsrmmdbasm' exited with code 1

 

Cause

Corruption in the NetWorker media database.

 

Resolution

WARNING: Media database corruption can lead to data loss. The inability to back up a bootstrap also leaves a datazone exposed to issues if a bootstrap recovery is required due to server issues. Contact Dell Support before proceeding.

A bootstrap backup of the NetWorker media database can be backed up and recovered directly using the "nsrmmdbasm" command. For details, see the following article: How To Export the NetWorker Media Database Using nsrmmdbasm

If both the Server Protection > Server backup > Server db backup action and the "nsrmmdbasm" command run manually fail, Dell Support must be engaged for assistance. Manual correction is required because there is no bootstrap database backup available to recover from. The following steps are required:

  1. Shut down the NetWorker server services.
  2. Compressing a copy of the "/nsr/mm/mmvolrel" folder and upload the compressed file.
  3. Rename the mmvolrel folder and replace the folder with the Support-provided, fixed copy.

Open a Service Request with NetWorker support when the environment is ready to proceed with the repair.
