SCSD Tape Drive Service Aid
This service aid allows you to obtain the status or maintenance information from a
SCSD tape drive. Not all models of SCSD tape drive are supported.
The service aid provides the following options:
v Display time since a tape drive was last cleaned. The time since the drive was last
cleaned displays on the screen, as well as a message regarding whether the drive is
recommended to be cleaned.
v Copy a tape drive’s trace table. The trace table of the tape drive is written to
diskettes or a file. The diskettes must be formatted for DOS. Writing the trace table
may require several diskettes. The actual number of diskettes is determined by the
size of the trace table. Label the diskettes as follows:
TRACE
x
.DAT (where
x
is a sequential diskette number). The complete trace table
consists of the sequential concatenation of all the diskette data files.
When the trace table is written to a disk file, the service aid prompts for a file name.
The default name is: /tmp/TRACE.
x
, where
x
is the AIX name of the SCSD tape
drive being tested.
v Display or copy a tape drive’s log sense information. The service aid provides
options to display the log sense information to the screen, to copy it to a DOS
formatted diskette, or to copy it to a file. The file name LOGSENSE.DAT is used
when the log sense data is written to the diskette. The service aid prompts for a file
name when you have selected that the log sense data is to be copied to a file.
This service aid can be run directly from the AIX command line. See the following
command syntax (path is /usr/lpp/diagnostics/bin/utape):
utape [-h | -?] [-d device][-n|-l|-t]
OR
utape -c -d device [-v] {-n | {-l | -t} { -D | -f [ filename]}}
Flag Description
-c Run the service aid without displaying menus. The return code indicates
success or failure. The output is suppressed except for the usage statement
and the numeric value for hours since cleaning (if -n and -D flags are used).
-D Copy data to diskette.
-f Copy data to the file name given after this flag or to a default file name if no
name is specified.
-h, -? Display a usage statement and/or return code. If the -c flag is present, only the
