dear group,

After i installed a DDS3 SDT 9000 12/24gb dat=20
Tape from sony i start with dump backup

but i need any parameters for "dump" i dont found=20
the right tape size parameters, and the manual from=20
sony tel me nothig about "blocksize, density, records"

its possible to save it the right tape size parameters
to the dump settings or to the kernel ?,

# dmesg | grep st0
>st0 at scsibus0 target 6 lun 0: <SONY, SDT-9000, 0403> SCSI2 1/sequential =
removable
>st0: density code 19
               --> ^^

# mt -f /dev/rst0 status
>SCSI tape drive, residual=3D0
>ds=3D3<Mounted>
^^^^^^^^^^^^^^
>er=3D0
>blocksize: 0 (0, 0, 0, 0)
>density: 19 (0, 0, 0, 0)
	  ^^
>current file number: 2
>current block number: -1

what he thel me here please ?

# man mt=20

i dont understand in the "man mt" how i can change the tape "density code 1=
9"
i want change it to 37 :-),
