A user metadata record consists of a set of attributes. The set of possible attributes is defined by the schema. Only one schema exists for each 5800 system. For information on configuring a schema, see “Configuring Metadata and File System Views” in Sun StorageTek 5800 System Administration Guide.
The 5800 system emulator loads its schema from an XML file. The metadata_merge_config utility can be used to extend the default schema, appending the new entries to the original schema, which is then read by the emulator. For additional information, see Chapter 2, Example Applications and Chapter 3, Sun StorageTek 5800 System Emulator.
