5. Click Next Step. The next Tape Drive Parameters window opens (Figure 73). Figure 73 Create Virtual Library Wizard window (6 of 12) . 6. Enter the number of tape drives you want to create in the library at this time in the Tape Drives box, if different from the default value. You can add more tape drives to the library later. The Tape Drives box defaults to the standard number of drives for the library type. NOTE: All the tape drives created at one time are mapped to the same Fibre Channel host ports. Make sure to load-balance the tape drives across the Fibre Channel host ports to obtain maximum performance. Tape drives in a library do not have to be mapped to the same port as the library. 7. To enable software data compression for the tape drives on the VLS6100, VLS6500, or VLS6800, select Enable Compression. Software data compression (2:1) is performed only on data handled by tape drives with data compression enabled. Data compression allows the VLS to store more data. Hardware data compression is used on the VLS6600; therefore, software compression is not used. NOTE: A tape drive created with data compression enabled cannot be changed to disabled later. 8. Click Create Tape Drive. A summary window opens and displays details about the tape drives created. HP StorageWorks 165
