Considering the method of taking tapes out of the STK9310 tape library is purely manual, error prone, and inefficient, the commands of searching the database provided by the Legato NetWorker software and the commands of searching the tapes provided by ACSLS are thoroughly studied, and the networker architecture is analyzed in detail, based on the premise that Legato NetWorker server and ACSLS server are accessible to each other remotely without a password. A shell script is designed in the HP UX environment to realize the automatic retrieval of tapes that had been full of data and to identify whether the data are in the tape library or not, thus to decide which tapes should be taken out of the tape library and produce a tape list incidentally.
