SCSI Tape Drive Service Aid
This service aid enables you to obtain the status or maintenance information from a
SCSI 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 displays on the screen. In addition, a
message indicating 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, but 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 SCSI 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 to be copied to a file.
This service aid can be run directly from the AIX command line. The syntax of the
command is as follows (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
-c
-D
