When you load a database dump from a volume that contains multiple dump files, specify the dump file name.
If you specify only the database name, Backup Server loads the first dump file into the specified database.
load database pubs2 from "/dev/rdsk/clt3d0s6"
To avoid this problem, specify a unique dump file name each time you dump or load data. To get information about the dump files on a given tape, use the listonly = full option of load database.
