| How to tell what ethernet settings you have? |
1. THE NDD WAY: "ndd /dev/hme \?" will give a list of variables, and ndd /dev/hme variable-name will return the value. if link_speed = 1, you are running 100Mb/s, if link_speed=0, you are running 10mb/s. Likewise, link_mode=1 means full duplex, link_mode=0 means half duplex. 2. THE DMESG WAY: dmesg | grep hme will give Human readable output as to link speed and mode. 3. THE SNEAKY WAY: netstat -k hme0 |

HP SureStore DAT - Verifing Installation in UNIX (R)
In this document:
Overview
As part of the installation process, you will have installed the appropriate device driver for your UNIX (R) system, and created device files to communicate with the tape drive. This section describes how you can verify that the installation has been performed correctly. In outline, the procedure is as follows:
- Write test data to a tape.
- Read the test data from the tape.
- Compare the data read from the tape with the original data on disk.
Verifying the Installation
- Test the SCSI connection to the
tape drive by doing a rewind operation:
- Remove tape cartridge, if there is already one in the drive.
- Insert a tape cartridge.
- Rewind the tape using the command line:
% mt -t <archive name> rewind
- or for SCO UNIX:
% tape -a /dev/rStpX rewind
If you do not see the Tape light flash as the
tape rewinds, the hardware installation may be faulty. Check the
troubleshooting section for help in identifying the problem.
- Write a sample file to tape, using 'tar':
% cd /
% tar cvf <archive name> <file>
The options to tar have the following meanings:
| c | Create a new archive on the device. |
|---|---|
| v | Operate in verbose mode. |
| f | Specify the archive name explicitly. |
The arguments follow the cvf options in the
command line. Their values depend on the operating system; suggested values
are given in System-Specific Arguments below,
click here to go to that section
now.
The arguments are as follows:
| <archive name> |
The name of the archive to be created. Example: /dev/rmt/0m |
|---|---|
| <file> |
The name of the file to put into the
archive, prefixed with './'. Example: ./stand/vmunix |
NOTE: Make sure you prefix the file name with a '.' when you back it up to tape. If you do not, the restore operation in step 2 will overwrite the original copy on disk.
- Read the file back from tape:
% cd /tmp
% tar xvf <archive name>
The 'x' option to tar here means "extract
from the archive".
Use the same value for the <archive name>
argument as in step 2.
- Compare the original with this retrieved file:
% cmp <original file> /tmp/<retrieved file>
This step compares the retrieved file and the
original file byte by byte. If they are the same, there
should be no output, and this verifies that the
installation is correct.
The arguments are as follows:
| <original file> | The name
of the original file, prefixed with '/'. Example: /stand/vmunix |
|||
| <retrieved file> | The name
of the file retrieved from the archive. Example: stand/vmunix |
|||
Example
Suppose you are verifying the installation of an HP DDS-format tape drive on an HP-UX 10.X system. The procedure would be as follows. Click here to see System-Specific Arguments below for the choice of <archive name> and <file> arguments:
- Change directory to root:
% cd /
- Back up /stand/vmunix to tape:
% tar cvf /dev/rmt/0m ./stand/vmunix
Note the prefix of '.' to the filename.
- Change to the temporary directory:
% cd /tmp
- Extract the file from the tape:
% tar xvf /dev/rmt/0m
- Compare the original with the restored version:
% cmp /stand/vmunix /tmp/stand/vmunix
Note that the original filename is not
prefixed with '.'.
System-specific arguments
The following table lists suggested values for the arguments <archive name> and <file> in the verification procedure described above:
| System | <file> | Desc. | <archive name> | Notes |
| DEC | vmunix |
OSF kernel |
/dev/rmt/Ym | Y is the instance of the drive. |
|
HP-UX 9.x and earlier |
hp-ux | HP-UX kernel | /dev/rmtcxxxdIl |
xxx is the SCSI card. I is the device number. l is the density. (See man 7 mt for further details.) |
| HP-UX 10.x |
stand/ vmunix |
HP-UX kernel | /dev/rmt/Ym | Y is the instance of the drive. |
| IBM AIX | unix |
AIX kernel |
/dev/rmt/X.1 |
X is the device ID reported back as available when you ran 'smit -C tape' to create the device files. |
|
Silicon Graphics IRIX |
unix |
IRIX kernel |
/dev/rmt/tpsCdX |
X is the SCSI ID of the drive. C is the SCSI card. |
|
Sun Solaris 1 (SunOS 4.1.x) |
bin/csh | C shell | /dev/rst0 | If you installed with SCSI ID 4. |
| /dev/rst1 | If you installed with SCSI ID 5. | |||
|
Sun Solaris 2 (SunOS 5.x) |
bin/csh | C shell | Determine the archive name as described below*. | |
| SCO | unix |
SCO kernel |
/dev/rStpY |
Use the device file created during the running of 'mkdev tape',where Y is the instance of the tape drive. |
*For Sun Solaris 2, determine the archive name by typing:
% ls -l /dev/rmt/*m | grep "st@X"
where X is the SCSI ID.
Identify the line for the tape drive. For example, if the drive was at SCSI ID 2, look for the line containing 'st@2,0'. This might be as follows (but on a single line):
lrwxrwxrwx 1 root root 63 Mar 1 00:00 /dev/rmt/0m ../../devices/sbus@1f,0/espdma@e,8400000/esp@e,8800000/st@2,0:m
Here you could use /dev/rmt/0m (shown in bold
above) as the archive name.
