Causa raiz do problema

O problema surgiu porque uma operação anterior de nova rotulagem falhou ao ler o rótulo da fita, causando uma entrada duplicada do nome do volume.

Quando o rótulo não puder ser lido, a fita será considerada em branco e a entrada de volume antiga no banco de dados de mídia será removida.

O banco de dados de mídia impede a criação de entradas duplicadas. Uma operação de rótulo falhará se já existir uma entrada para esse volume no banco de dados.

Error: Duplicate volume name `VOLUMENAME'. Select a new name or remove the original volume

Resolvendo o erro de nome de volume duplicado

Para resolver o erro de nome de volume duplicado, o administrador do Avamar Extended Retention (AER) deve consultar o banco de dados de mídia em busca de quaisquer savesets nesse rótulo de volume. Depois de confirmado que não há salvamentos nesse rótulo de volume, a entrada antiga do rótulo de volume deve ser removida manualmente antes de rotular uma fita.

Primeiro, verifique se o nome do volume não existe no banco de dados de mídia executando o seguinte comando:

root@AvaUtilityNode:~/#: mminfo -avot -q volume=VOLUMENAME

Depois de confirmado que um volume não existe no banco de dados de mídia, use este comando para excluir esse volume:

root@AvaUtilityNode:~/#: nsrmm -d VOLUMENAME
Delete file and media index entries for LTO Ultrium-5 tape VOLUMENAME? y

Em seguida, repita a operação de rótulo usando o comando abaixo e use a seguinte sintaxe.

where 
-f=tape_device_path ; -S=Slot_where_tape_is ; -b=Pool_Name ; "-vvvv=verbose level 4"; "-j=JukeboxName"; "-L=label operation
