I did the following:

amrmtape MF_TEST MF_TEST_002
amadmin MF_TEST find mws_test     
     (MF_TEST_002  is clean)
amlabel -f  MF_TEST MF_TEST002 
     (recreate label)
amcheck MF_TEST
     (no error)

So far, the tape MF_TEST_002 is clean.

After a successful 'amdump MF_TEST', I run 'amadmin MF_TEST find mws_test',
I still see 'history' in the tape:
date       host     disk  lv tape or file file status
2003-04-02 mws_test /      0 MF_TEST_001     1 OK

How to clean the 'history' ? I only need one set index

Thanks!
