The Archive tape controller is a Sun `QIC-II' interface to an Archive streaming tape drive. It provides a standard tape interface to the device, see mtio.4 with some deficiencies listed under BUGS below.
The maximum blocksize for the raw device is limited only by available memory.
ar*: no such drive
ar*: no cartridge in drive
ar*: cartridge is write protected
ar: interrupt from unitialized controller %x
ar*: many retries, consider retiring this tape
ar*: %b error at block # %d punted
ar*: %b error at block # %d
ar: giving up on Rdy, try again
The FSR ioctl is not supported.
The system will hang if the tape is removed while running.
When using the raw device, the number of bytes in any given transfer must be a multiple of 512 bytes. If it is not, the device driver returns an error.
The driver will only write an EOF mark on close if the last operation was a write, without regard for the mode used when opening the file. This delete empty files on a raw tape copy operation.
