Explanation: A requesting process or vmd encountered an invalid or an unknown database or communications protocol. The possible data stores that an error affects are volume, volume pool, bar code rule, global device database, and shared drive information.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Identify the target components (for example, vmd and daemons or services, or user interfaces on local or remote hosts). Verify that all Media Manager binaries are at a compatible version level. Depending on which requests encountered the invalid version, determine whether or not the database is corrupt. Use an appropriate interface to query for the type of information that is involved in the error condition.
