Creating the Device Files Once you have verified the tape drive connection, you will need to create the appropriate device files for the drive. Normally, you would have rebooted your system after attaching the tape drive, and this process runs insf However, if you have not rebooted your system since attaching the drive, you...

[-u] Berkeley and AT&T modes differ in their read-only close behavior: In Berkeley mode, the tape position will remain unchanged by a device close operation. In AT&T mode, a device close operation will cause the tape to be repositioned just after the next tape filemark (the start of the next file).

    In order to enable large transfers under Linux (>64 KB per write), edit the file and change the /usr/src/linux/drivers/scsi/st_options.h definition of ST_BUFFER_BLOCKS If you want requests to space to end of data to be faster, you should also enable in the same file. After changing this file, rebuild the ST_FAST_MTEOM modules and install the new binary.

    For example, for an ESP-based adapter: % dmesg | egrep ".*esp.*target" | sort | uniq This produces a list similar to: sd0 at esp0: target 0 lun 0 sd6 at esp0: target 6 lun 0 This indicates that SCSI IDs 0 and 6 are used for existing devices. SCSI ID 7 is generally used for the adapter itself.
