Avamar: Falha de backup AV/DD com token inválido devido a Key Magic inválido

Os backups integrados do Avamar com Data Domain falham. Quando os logs avtar são consultados, o erro parece ser um token inválido:

Consulta de /usr/local/avamar/var/ddrmaintlogs/ddrmaint.log mostra que a solicitação de token falhou:

<snip>

Analisando o /ddr/var/log/debug/ddfs.info log-on O Data Domain revela que a criptografia de token falhou devido a uma mágica de chave inválida:
1. Faça log-in no Data Domain.
2. Analise a ddfs.info Registre usando o seguinte comando:

log view debug/ddfs.info

Como alternativa, se for preferencial, o 323235 de KB pode ser usado para sair para o modo bash e navegar diretamente para ddfs.info.

.

1. Revogar o acesso ao token do usuário ddboost:

2. Abra o servidor Data Doman no Avamar Administrator:-

• No Avamar MCGUI, vá para Server > Server Management.
• Selecione o servidor DD
• Clique em "Edit Data Domain System icon".
• Clique em OK na janela pop-up.

3. Reinicie o DD Boost no sistema Data Domain:

ddboost disable
ddboost enable

4. Teste outro backup para garantir que isso resolveu o problema de token inválido.
