NetBackup status code: 2106
Message: Disk storage server is down
Explanation: This error can occur when a job uses a disk storage unit whose disk group resides on a storage server that NetBackup has marked down. This error can also occur when a cloud storage backup fails.
Recommended Action: Verify that all media servers that are configured for the storage server can communicate with the storage server. The bpstsinfo command queries the storage server periodically, so you can use the bpstsinfo log set to verbosity level 5 on the media server.
If the error is related to a cloud storage backup failure, you should verify the following information:
The NetBackup CloudStore Service is running on the master and media servers. See the NetBackup CloudStore Service Container startup and shutdown troubleshooting section in the NetBackup Cloud Administrator's Guide for information on how to start the service.
The NetBackup certificates are stale/unavailable on the configured media server, which can cause the storage server to go down. Ensure that you deploy all of the required certificates on that media server to keep the storage server up. For more information, see the NetBackup Security Encryption Guide.
The option on the NetBackup master server is selected if the media server is version 8.0 or earlier. The option is available in the NetBackup Administration Console on the tab.
