StorageWorks DLT 10/20 GB Cartridge Tape Drive
C–6
Order Number: EK-SM1TB-UG. E01
C.3.1.2 System Shutdown
After you have edited the “st.conf” file, shut down the system as follows:
sync
cd /
shutdown -i0 -g0 -y
C.3.1.3 Installation of the Tape Drive
Install the tape drive into the storage subsystem and power on the workstation. We
recommend that the SWXTL SCSI device address be set to ID 4 or 5.
NOTE
If your SCSI host adapter is supported by the
“probe-scsi”
command, then you can use this command at the boot prompt
to verify that the connected device is correctly attached to the
system.
C.3.1.4 Rebooting of System
Reboot the system using the following command at the boot prompt:
>boot -rv
Note that 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 SWXTL SBB. Since you booted the system using the verbose
switch, the system displays all of its SCSI targets. Verify that “
DEC 10GB 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 0x81, (TK87, compressed) density mode.
•
Option xl, corresponds to the 0x17 (TK85) density mode.
•
Option xm corresponds to 0x18 (TK86) density mode.
•
Option xh corresponds to 0x80 (TK87, 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.
