Symptoms

Cuando se usa la llamada liaRunOsPatching de la API REST con el parámetro isRunningInParallelOnPds, el proceso de actualización no se ejecuta en los nodos en paralelo según lo esperado.

Los siguientes ejemplos se refieren a un sistema PowerFlex Management Platform (PFMP) 4.x, pero también se producirán en un sistema PFMP 5.x.

Ejemplo:

SDS_x.x.x.179 es el último en PD4 y SDS_x.x.x.178 es el primero en PD3; se procesan en paralelo:

Impacto

Las actualizaciones del SO tardan más de lo esperado en completarse.

 

Cause

Debido a un problema de software en la lógica de actualización del sistema operativo, el proceso destinado a ejecutar comandos en los nodos de un PD en paralelo se ejecuta secuencialmente.

Resolution

No hay ninguna solución alternativa disponible.
