Tivemos uma queda de energia em nosso data center na semana passada e quando nosso PIX 515E duplo executando o IOS 7.0 (8) (configurado com um cabo de failover) voltou, eles estavam em um estado de failover onde a unidade Secundária está ativa e a unidade Primária está em espera Eu tentei 'failover reset', 'failover ativo' e 'failover reload-standby', assim como a execução de recarregamentos em ambas as unidades em uma variedade de pedidos, e eles não retornam Primário / Ativo Secundário /Espera. A única coisa no meu arsenal que eu não tentei é dirigir até o data center e executar uma reinicialização difícil, que eu odeio fazer.
Li Como o failover funciona no firewall seguro da Cisco e parece que isso deve ser perverso para a frente.

Não sei exatamente como interpretar os dados do syslog. A Primária não parece tentar se tornar Ativo. Quando eu recarrego as unidades individuais separadamente, minhas conexões são mantidas, então não parece que eu tenha uma falha real de hardware. Existe algo que eu possa consultar (IOS ou SNMP) para verificar problemas de hardware?
Alguma ideia? Meu IOS-fu é fraco.
Obrigado por qualquer ajuda que você possa fornecer,
