Use obtar -Xreuse to reuse volumes. Reusing a volume is similar to unlabeling it, but obtar preserves the existing volume label.
obtar -Xreuse [-f device ] [ -Xow ]
You can specify a number of options with obtar -Xreuse; this section describes those options that you are most likely to use. Refer to "obtar Options" to learn about additional obtar -Xreuse options.
deviceSpecifies the name of the device in which the volume is loaded. The device argument to -f is the name that you have assigned to a tape drive in an administrative domain.
Directs obtar to disregard any expiration date in the volume label. If you try to overwrite a volume that has not yet expired, then the operation fails unless you specify -Xow.
Example 4-35 reuses the tape volume in tape0.
