Figure 309. TAPEUTIL Program Menu
APPENDA
|
If command-line parameters are provided when the program is invoked, the command-line mode will be
|
started. For each command-line execution of the program, the device is first opened, the specific
|
command is issued, and the device is then closed. The program can be driven from within a shell script if
|
desired. Results of the operation will be displayed only when executed in verbose mode. No information is
|
displayed when not in verbose mode. This is particularly useful for quiet shell script implementations. A
|
completion code, as defined in
/usr/include/sys/errno.h for the operation requested is always returned from
|
the program upon exit (in both verbose and quiet mode).
|
Note: Options 4 through 8 of the tapeutil program supported only by the 3570 and the 3590.
|
The usage of the tapeutil program in command-line mode is as follows:
|
tapeutil -f device -o operation [options]
|
where device is the name of the tape device special file (for example: /dev/rmt/1st) and operation is one
|
of the values listed below. The device special file and the operation are required. The specific options
|
associated with a particular operation are indicated in Figure 310, Figure 311 on page APPENDA-4,
|
Figure 312 on page APPENDA-4 and Figure 313 on page APPENDA-5. Parameters enclosed in square
|
brackets are optional. All others are required.
