SCSD Tape Drive Service Aid
This service aid provides a means to obtain the status or maintenance information from
a SCSD tape drive. Only some models of SCSI 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 is displayed onto the screen. In addition, a
message whether the drive is recommended to be cleaned is also displayed.
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 on the diskette. The
service aid prompts for a file name when the log sense data is chosen to be copied
to a file.
This service aid may be run directly from the AIX command line. The following usage
statement describes the syntax of the command (path is /usr/lpp/diagnostics/bin/utape):
Usage: utape [-h | -?] [-d <device>] [-n | -l | -t]
or utape -c -d <device> [-v] {-n | {-l | -t} { -D | -f [<filename>]}}
Flag
-c
-D
-f
-h, -?
-l
-n
Description
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 cleaned (if -n and -D flags are used).
Copy data to diskette.
Copy data to the filename given after this flag or to a default filename if no
name is specified.
Display a usage statement and/or return code. If the -c flag is present, only the
return code displays to indicate the service aid did not run. If the -c isn't used,
a usage statement displays and the service aid exits.
