NetBackup status: 2107, EMM status:
Requested media server does not have credentials or is not configured for the storage server), because the READ host selected does not have credentials.
When we are facing to the situation where the duplication is failed do to this scenario..
It's been noticed in certain situations there are concerns over how NetBackup plays duplications using optimized duplication (opt-dup). Relying on the version deployed, backups may be performed the usage of one media server, but a duplication can use a distinct media server. With opt-dup duplications the media server defined to perform the examine operation has little or no requirement to do any paintings, because the work is finished by means of the storage server that's associated to the disk pool, where the preliminary backup is living. The media server action is to just initiate the challenge (similar to an orchestra conductor), it's left to the storage server to send the information to the far flung vacation spot and destination disk pool.
Relying upon the NetBackup and garage server configurations, there may be a opportunity opt-dup duplications can fail with credential mistakes, *if* the backup is finished to a disk pool which simplest has a single media server selected, but, the destination disk pool has multiple media servers selected. The trouble occurs because sources are allocated for the vacation spot garage unit, and if a media server selected is not a media server which has get right of entry to to the disk pool wherein the preliminary backup became done, a credential failure will seem and the duplication fails.
The truth we see a one-of-a-kind media server indexed, does no longer indicate this media server is sending records throughout the network, it’s just telling the storage server to do the work.
Whilst optimized duplications are completed the ALTREADHOST and the -COMMON_SERVER_FOR_DUP options are not adhered to. That is because despite the fact that another media server is registered as appearing the study operation, in actual fact the opt-dup operation remains finished by the storage server related to the authentic deduplication disk pool (OST plugin does the work).
The optimized duplications fail with STATUS 2107 (NetBackup status: 2107, EMM status: Requested media server does not have credentials or is not configured for the storage server), because the READ host selected does not have credentials.
NetBackup storage server and disk pool configurations do not have the same media servers defined at both the read and write sides of the optimized duplication process.
Solution of Netbackup status 2107
NetBackup is working as designed and this is documented in the Veritas NetBackup 7.5 Deduplication Guide page 39, and at the time this technical article was written, there are no known plans to alter this behaviour.
