Rebooting of System
Reboot the system using the following command at the boot prompt:
>boot -rv
NOTE:
The switch "
r"
forces the kernel to be re-configured, and switch "
v
" enables a
display of the system configuration at boot time
The system compiles the kernel and creates special files in /dev so that it can
communicate with the TZ 89 DLT Cartridge SBB Tape Drive. Since you
booted the system using the verbose switch, the system displays all of its SCSI
targets. Verify that “
DEC 70GB Cart. DLT Streaming /w
Compression
” is displayed as a target when the system is booting.
At this time, the tape drive is configured in the /dev directory in two ways:
rmt format, and rst format.
“rmt” format
In this format, the drive is configured with various options. For further
explanations, see the man pages on “
st
” (the modes are x, xl, xm, xh, xc, and
xu, where x is the rmt number).
■
Options x, xu, and xc, correspond to the 0x85 (
CT-IV
, compressed)
density mode.
■
Option xl, corresponds to the 0x82 (
CT-IV
) density mode.
■
Option xm corresponds to 0x83 (
CT-IV
) density mode.
■
Option xh corresponds to 0x84 (
CT-IV
, native) density mode.
■
Option b associates with the BSD behavior and is for backward
compatibility on all of the above options. For further information, refer
to the man pages of “
mtio
”.
■
The n option provides access to the device with no rewind, similar to
nrst (below), and is also applicable to all of the above options.
