StorageWorks DLT 10/20 GB Cartridge Tape Drive
E–4
Order Number: EK–SM1TB–UG. E01
where:
#
specifies an arbitrary number to distinguish this tape drive from others
N
specifies no rewind on close
b
specifies Berkeley behavior
NOTE
This tape drive will read both TK85 (2.6 MB) and TK86 (6.0 MB)
densities but will not write these densities to the above device files.
Use the front panel override button to write these densities.
To list the device files associated with each device, issue the command “ioscan -f -n/more”.
E.4
Series 800 System Device Files
The System Administration Manager program automatically creates the appropriate device
files and places them in the /dev/rmt directory when adding the device through SAM.
Additionally, the device files are created automatically upon system initialization..
E.4.1 HP–UX 9.04
The following naming convention is used for the tape drive SBB, as shown in the examples
listed below:
/dev/rmt/lu[l|m|h[c]][n][b]
where:
lu
specifies the logical unit as reported for the tape drive using the “ioscan -
f” commmand
h/l/m/c
specifies density, with
h
meaning high density,
l
meaning low density,
m
meaning standard DDS format, and
c
meaning data compression

n
specifies no rewind on close
b
specifies Berkeley behavior
For additional information about DDS tapes, refer to mt(7) of the HP-UX Reference manual
(P/N B 2355-90033).
Example
If you were to install a tape drive SBB in the StorageWorks SWXSE-02 expansion
enclosure, the following device files would be produced for the device having a logical unit
number of 4 in the directory /dev/rmt:
4hc
4l
4hcb
4lb
4hnc
4ln
4hncb
4lnb
4h
4m
4hb
4mb
4hn
4mn
4hnb
4mnb
1
The h, l, and m device designations all yield the same result. To disable compression, use the front panel
override button and select the desired density
