Default value: The value of the rewind parameter is used.
Used by BRBACKUP and BRARCHIVE to rewind a tape after a backup and set it to offline. This means that the volume is automatically ejected from the tape device (even when you are backing up to a remote system using
pipe or pipe_auto ).Required value: The rewind/set offline command for your host operating system.
You could make the following entry, for example:
rewind_offline = "mt -t $ offl"

Rewind commands:
HP-UX:
"mt -t $ offl" ; AIX: "tctl -f $ offline" ; OSF/1, SINIX, SUN, NT: "mt -f $ offline" ;Make sure that you do not forget the double quotes when you enter parameters composed of several values.
Make sure that you replace the device address with the character $, as shown in the example. The SAP utilities replace the $ character with the address of the device you use.
