RecoverPoint for VMs: Volumes de registro bloqueados em hosts ESXi específicos podem levar à indisponibilidade da replicação de dados e à regulagem de reinicialização.

O RecoverPoint for Virtual Machines usa volumes de registro para rastrear e gerenciar imagens point-in-time.
Em um ambiente RP4VMs, pode ocorrer um problema que bloqueia um volume de registro em um único host do ESXi.
Se o par do vRPA atribuído para replicar as VMs for acionado em vMotion para um host do ESXi diferente, poderá ocorrer a replicação de dados indisponível (DRU).

Isso pode afetar todos os grupos de consistência (CGs) atribuídos a um RPA específico, o que fará com que o status seja DISABLE ou ERROR.

Podem ser observadas falhas no processo de replicação:

replication Sun May 19 20:12:01 UTC 2024

replication Sun May 19 20:37:55 UTC 2024

replication Sun May 19 20:38:21 UTC 2024

replication Sun May 19 22:32:26 UTC 2024

replication Sun May 19 23:03:56 UTC 2024

replication Sun May 19 23:28:46 UTC 2024

Isso resulta na desconexão do RecoverPoint Appliance (RPA) do cluster.

A causa dessa situação está sendo investigada.
Nenhuma resolução permanente está disponível atualmente; no entanto, é uma situação específica do RP4VMs.

A situação pode ocorrer em vários cenários:

1. Quando o vRPA responsável pela proteção de uma VM é transferido pelo vMotion para outro host do ESXi como o host do ESXi original, o registro é bloqueado nesse host do ESXi específico.

2. Quando um grupo de consistência move a propriedade de um par de vRPA para outro, invocando assim a situação acima.

Resolução:
Existe uma solução para esse problema, mas é necessária a intervenção da equipe de suporte técnico da Dell Technologies.  Os logs adequados do RP4VMs, do ESXi e do vCenter devem ser coletados para triagem dessa situação e encaminhados conforme necessário. Entre em contato com o Centro de suporte ao cliente da Dell Technologies ou com seu representante de serviço para obter suporte técnico e consulte este ID da solução da base de conhecimento da Dell Technologies.
