Symptoms

Ao usar a chamada da API REST liaRunOsPatching com o parâmetro isRunningInParallelOnPds, o processo de atualização não é executado nos nós em paralelo como esperado.

Os exemplos abaixo referem-se a um sistema PowerFlex Management Platform (PFMP) 4.x, mas também ocorrerão em um sistema PFMP 5.x.

Exemplo:

SDS_x.x.x.179 é o último no pd4 e o SDS_x.x.x.178 é o primeiro no pd3 - eles são processados em paralelo:

Impacto

A atualização do SO leva mais tempo para ser concluída do que o esperado.

 

Cause

Devido a um problema de software na lógica de atualização do sistema operacional, o processo destinado a executar comandos em nós de um PD em paralelo é executado sequencialmente.

Resolution

Não há solução temporária disponível.
