How to reuse a tape after a backup failed and tape was not used

Table of contents
No headers

Summary: If a backup fails and nothing is written to tape amanda will skip this tape and mark it used, thereby wasting this tape

Example of failed backup and unused tape:

2006-06-01 01:00:02 ppragin.zmanda.com /home/vmware/fc5  1 DailyTape-10 0   -- FAILED (chunker) [cannot  read header: got 0 instead of 32768]
2006-06-01 01:00:02 ppragin.zmanda.com /home/vmware/fc5  1 DailyTape-10 0   -- FAILED (chunker) [cannot read header: got 0 instead of 32768]
2006-06-02 01:00:02 ppragin.zmanda.com /home/vmware/fc5  0 DailyTape-01

Solution: To salvage this tape and let amanda use this tape in later backups:
1.amrmtape $CONFIG $TAPEYOUWANTTOREUSE
2.amlabel $CONFIG $TAPEYOUWANTTOREUSE slot $slotnumber

-bash-3.00$ amrmtape tape DailyTape-10
amrmtape: remove label DailyTape-10.
amrmtape: preserving original database in curinfo.orig.18318 (exported).
-bash-3.00$ amlabel tape DailyTape-10 slot 10
labeling tape in slot 10 (/dev/nst0):
rewinding, reading label DailyTape-10
rewinding, writing label DailyTape-10, checking label, done.
