HP Q1581A HP DDS/DAT drives UNIX, Linux and OpenVMS configuration guide (DW049 - Page 28

HP DDS-format drives will work with tar, cpio, backup, restore and dd. For systems other than the 43P, the drive is also boot-capable, provided a boot tape is generated using mkszfile and mksysb. Once device files have been created, you should confirm that your new tape drive is working properly. Chapter 8, "Verifying the installation" provides instructions on backing up and restoring a sample file to test your installation. Device filenames under AIX Use device filenames as listed below for the combination of Rewind on Close, Retension on Open, and Compression that you want: Filename /dev/rmtn /dev/rmtn.1 /dev/rmtn.2 /dev/rmtn.3 /dev/rmtn.4 /dev/rmtn.5 /dev/rmtn.6 /dev/rmtn.7 Rewind on Close Yes No Yes No Yes No Yes No Retension on Open No No Yes Yes No No Yes Yes Compression enabled enabled enabled enabled disabled disabled disabled disabled The n in the filename is the instance number assigned to the drive by the operating system, where 0 is the first device, 1 is the second and so on. Rewind on Close Retension on Open Compression Normally, the drive repositions the tape to BOT (Beginning of Tape) when the device file is closed. Using the no rewind option is useful when creating and reading tapes that contain multiple files. Retensioning consists of winding to EOT (End of Tape) and then rewinding to BOT, in order to reduce errors. If this option is selected, the tape is positioned at BOT as part of the open process. Compression can be disabled or enabled. 28 IBM (AIX) servers and workstations
