Example:
If you were to install a tape drive SBB on the main (core) SCSI bus and in slot location 4 of
the StorageWorks SWXSE-02 expansion enclosure, the following device files would be
produced in /dev/rmt for a Series 700 computer:
c201d4c
c201d4l
c201d4cb
c201d4lb
c201d4cn
c201d4ln
c201d4cnb
c201d4lnb
c201d4h
c201d4m
c201d4hb
c201d4mb
c201d4hn
c201d4mn
c201d4hnb
c201d4mnb
E.2.1.4 Device Files (Series 800)
The System Administration Manager program automatically creates the appropriate device
files and places them in the /dev/rmt directory.
The following naming convention is used on Series 800 computers for the EXB-8505
Cartridge Tape Subsystem SBB, as shown in the examples listed below:
/dev/rmt/lu#_8mm{8200/8500}[n][c][b]
where:
lu#
specifies the logical unit number of the tape drive as reported from the
ioscan-f
command
n
indicates no rewind
c
indicates compressed data
b
specifies Berkeley behavior
Example
If you were to install a tape drive SBB on the main (core) SCSI bus and in slot location 4 of
the StorageWorks SWXSE-02 expansion enclosure, the following device files would be
produced in /dev/rmt, assuming a logical unit number of 8:
8_8mm8200
8_8mm8200n
8_8mm8500
8_8mm8500n
8_8mm8200b
8_8mm8200nb
8_8mm8500b
8_8mm8500nb
8_8mm8200c
8_8mm8200nc
8_8mm8500c
8_8mm8500nc
8_8mm8200cb
8_8mm8200ncb
8_8mm8500cb
8_8mm8500ncb
E.2.1.5 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/c201d4h /etc/passwd
or
tar cvf /dev/rmt/8_8mm8500c /etc/passwd
The system responds with something similar to the following:
a /etc/passwd 2 blocks
Note that depending on the size of the file, a different number of blocks may be reported.
