tape - magnetic tape maintenance
tape [-tape] [-a arg]
command [device]
The tape command performs control operations on tape
devices. If no device is given on the command line, the file
/etc/default/tape is scanned for a line beginning with `device='; the
remainder of the lines specifies the default device.
The command argument may be one of:
- status
- Print status information about the drive.
- reten
- Retension the tape.
- erase
- Erase the tape.
- reset
- Reset tape drive.
- rewind
- Rewind tape.
- rfm
- Skip to the next file.
- eod
- Seek to the end of written data.
- wfm
- Write a filemark at the current position.
- load
- Load the tape device.
- unload
- Unload the tape device.
- setblk
- Set the block size (in bytes) for the tape device.
- setcomp
- Set tape compression. A value of 0 means no compression, all other values
mean compression
- setdensity
- Set tape density (in hexadecimal). Some density codes are: 0 = default
(autodetect); 4 = QIC-11; 5 = QIC-24; F = QIC-120, 10 = QIC-150; 11 =
QIC-320; 14 = EXB-8200; 15 = EXB-8500; 15 = QIC-1000; 22 = QIC-2GB; 8C =
EXB-8500c; 90 = EXB-8200c.
The -a option gives a count for the rfm, wfm,
setblk, setcomp, and setdensity commands.
The [-tape] option is currently ignored.
