Appendix D. Product Notes for Hewlett-Packard

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.
