E.4.2 HP-UX 10.00
The following naming convention is used on systems which support long filenames for the
DLT format tape drive SBB, as shown in the examples below:
/dev/rmt/c#t#d#BEST[n][b]
where:
c#
specifies the instance number of the interface card
t#
specifies the SCDI address of the tape drive
d#
specifies the device number (LUN) at the SCSI address
BEST
specifies the highest capacity density, which for this device is the TK87
compressed format
n
specifies no rewind on close
b
specifies Berkeley behavior
Examples:
For a tape drive SBB installed in slot location 4 of the StorageWorks SWXSE-02 expansion
enclosure connected to the main (core) SCSI bus, the following device files would be
produced in the directory /dev/rmt:
c0t40BEST
c0t40BESTnb
c0t4d0BESTb
c0t40BESTnb
For systems which do not support long file names, the following device naming conventions
is used:
#m
#mb
#mn
#mnb
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.5
Testing the Tape Drive
To test the tape drive, back up the “passwd” file to tape using the “tar” command, as follows
(assuming that you installed the drive in accordance with the preceding example):
tar cvf /dev/rmt/4h /etc/passwd
