As the result of a RECONCILE VOLUMES command, the volume shown was found on both the source and target server, but the beginning portion of the high-level archive file name (the prefix) on the target server does not match the prefix in the device class on the source server.
The reconciliation process continues.
Verify that the prefix in the device class on the source server is correct and update it if necessary. Use the RECONCILE VOLUMES FIX=YES command on the source server to rename the target archive objects to match the device class on the source server.
