Solaris Device Driver (IBMtape) The default value for IBM_trace is zero (0). You can define another IBM_trace value by placing an entry in /etc/system, so that IBM_trace is set at each restart. For example, this entry in /etc/system sets IBM_trace to 2 at each restart: set IBMtape:IBM_trace = 2 When IBM_trace is set in /etc/system, it affects tracing during driver loading, initialization, and operation. You may also set or modify the IBM_trace value manually in an adb session. Because the driver must already be loaded and initialized before using this method, the trace value that is set is active only during driver operation.

The default value for IBM_trace is zero (0). You can define another IBM_trace
value by placing an entry in
/etc/system
, so that IBM_trace is set at each restart. For
example, this entry in
/etc/system
sets IBM_trace to 2 at each restart:
set IBMtape:IBM_trace = 2
When IBM_trace is set in
/etc/system
, it affects tracing during driver loading,
initialization, and operation.
You may also set or modify the IBM_trace value manually in an
adb
session.
Because the driver must already be loaded and initialized before using this
method, the trace value that is set is active only during driver operation.
In this sample session,
ksh>
is a shell prompt, and
adb>
is the
adb
session prompt.
Commands that you enter are in
boldface
. Explanatory comments follow pound
signs (#) or exclamation and pound sign pairs (!#). Text lines without a prefix are
adb

Running Diags_info Script
Run the diags_info script located in the /opt/IBMtape directory. This script detects
the problems on the configuration files, gathers important system HBAs and
configuration information. The script should be run as root. If not run as root, the
information should be labeled as such, but the value of the information is
degraded when run as a non-root user.
To facilitate capture of data, the script places information in a file called diags.out
in the directory locating the script. Send the output file to the location identified by
your IBM service representative.
iostat Command
IBMtape driver supports the iostat system command, which reports I/O statistics
for the supported tape drives in IBMtape.4.1.2.7 and later versions. Refer to man
(1M) iostat for the command usage.
