Síntomas
The NetWorker server protection bootstrap save set fails with the following error message:
Bootstrap fails: 4746:save: external ASM `nsrmmdbasm' exited with code 1
Causa
Corruption in the media database
Resolución
WARNING: Media database corruption can lead to data loss. The inability to backup a bootstrap will also leave a datazone exposed to issues should a bootstrap recovery be required in the event of server issues. Contact Support before proceeding.
A bootstrap backup of the NetWorker media database can be backed up and recovered directly using the nsrmmdbasm command: see How To Export the NetWorker Media Database Using nsrmmdbasm
In the case that both the Server Protection > Server backup > Server db backup action and the nsrmmdbasm command run manually fail, you will need to engage Support to assist with manual correction as there is no bootstrap database backup available to recover from. This will require:
- Shutting down the NetWorker server services
- Compressing a copy of the
/nsr/mm/mmvolrelfolder and uploading - Renaming the mmvolrel folder and replacing with the Support-provided, fixed copy
Open a Service Request with NetWorker support when you are ready to proceed with the repair.
