Backup jobs fail
If backup jobs fail with an Error 800: Disk Volume is Down message, examine
the disk error logs to determine why the volume was marked DOWN.
If the storage server is busy with jobs, it may not respond to master server disk
polling requests ina timely manner. A busyload balancing server also may cause
this error. Consequently, the query times out and the master server marks the
volume DOWN.
If the error occurs for an optimized duplication job: verify that source storage
server is configured as a load balancing server for the target storage server. Also
verify that the target storage server is configured as a load balancing server for
the source storage server.
