Administrar el hardware raid con el controlador Adaptec

Servidor Dedicado con Adaptec Raid Controller

Este artículo describe cómo monitorear y reconstruir tu hardware raid si tu servidor Linux tiene un Adaptec Raid Controller.

Con el software arcconf64 tienes la posibilidad de controlar el Raid Controller de tu servidor. Por ejemplo, puedes leer información y reconstruir un hardware raid en caso necesario. arcconf64 está instalado en el servidor de forma predeterminada.

 

  • Inicia sesión en tu servidor Linux a través de SSH y conviértete en root.

  • Lee la información sobre tu servidor usando el comando arcconf64 getconfig 1. Aquí hay un ejemplo:

Consulta los acontecimientos en el disco duro usando el comando getlogs 1 device.

Importante

Antes de reconstruir un hardware raid, asegúrate de que la opción Automatic Failover esté activada. Por defecto, este es el caso. Puedes activar la opción con el comando arcconf64 failover 1 on.

 

  • Introduce el comando arcconf64 reexplorar 1. En la mayoría de los casos, la reconstrucción del hardwaire raid comienza automáticamente. El proceso se realiza en segundo plano y puede durar varios minutos.

  • Si la reconstrucción no se inicia automáticamente durante la reexploración, elimine los metadatos del disco duro con el siguiente comando: arcconf64 TASK START 1 DEVICE 0 2 CLEAR, donde 0 representa el canal del controlador y 2 el puerto del disco duro.

  • Monta el disco duro reemplazado como Hotspare con el siguiente comando: arcconf64 SETSTATE 1 DEVICE 0 1 HSP LOGICALDRIVE 1. La reconstrucción se inicia automáticamente.
