Worker daemons are restarted. Error save error, media index problemNote Not all of the Symptoms listed above will be found in all Cases. However, each is indicative of index corruption therefore the fixes listed below are relevant to each situation. The above noted error messages are typically the result of problems in the media database. Dell EMC EMC Corporation until 2016 is an American multinational corporation headquartered in Hopkinton, Massachusetts, United States. Dell EMC sells data storage. Corruption in the media database could be caused by any number of events, such as hardware failure, or improperly shutting down Net. Worker daemons. The general approach to resolving any fatal media database problem is to use the nsrim, and nsrck tools. If those tools did not solve the issue, so you have to proceed with scavenging the Media Database. Follow the steps listed below to perform media database compression and consistency checks to correct possible media database corruption. Emc Powerpath License Server CompatibilityEMC specific. Using VMware vSphere with EMC VPLEX EMC Tech Paper Implementing vSphere Metro Storage Cluster vMSC using EMC VPLEX 2007545 VMware KB. Capacity License. If you plan to use capacity licenses, the following licenses must be obtained for IntelliSnap and the NetApp SnapVaultSnapMirror features. You may also follow this procedure to simply compress the backup servers indexes Client File Index, and Media Database as part of periodic system maintenance. Media Database Consistency Check Compression Ensure that there are no running jobs backup, recovery, cloning, etcStop Net. Worker daemonsservices Net. Worker Backup and Recovery Server and Net.

Worker to compress the media dbStart Net. Worker Services again first start the Net. Worker Remote Exec Service and then Net. Worker Backup and Recovery ServerRun the following command line nsrim XRun the following command line nsrck L6. If the problem has not been solved with the above steps, proceed with the following procedures for Media Database Scavenging Media Database Scavenging Make sure you have a bootstrap backup before commencing. Ensure that there are no running jobs backup, recovery, cloning, etcStop Net. Worker daemonsservices. Cause a controlled corruption by removing  nsrmmmmvolume. BE VERY CAREFUL WITH THIS STEP, Please read it all before proceeding. In nsrmmmmvolume. EXCEPT the 4 files ss. Vol. Hdr  You MUST keep those files. NOTE  Be careful when deleting the files and make sure not to delete the vol. These files are NEEDED to rebuild the media database. If you do rm ss, this will delete ss. Note this step is simply a way to force Net. Worker to rebuild the media database. The files that are deleted are all rebuild able from the media db file. The files mentioned above and cautioned to not delete them are not rebuild able, Net. Worker will not be able to rebuild your media db without these files ss. Empty the files in the nsrtmp directory. Restart Net. Worker daemonsservice. In the situation where the corruption is severe and the above procedure did not resolve the media database corruption, the media database can be recovered from the bootstrap using the mmrecov command to get a good copy of the media database. Net. Worker software attempts to generate a bootstrap every day, so no more than one day of data should be lost.
