Appendix D. Product Notes for Hewlett-Packard
Order Number: EK–STWCT–UG. E01 E–3
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.
