Falla de conexión: Automatización ¡NUEVO!
¡IMPORTANTE! Se lanzó una nueva función en xDoctor 4-8.104.0 y versiones posteriores. Esta base de conocimientos (KB) ahora está automatizada con la consola de servicios para intentar comprobar rápidamente las conexiones de los switches. El script detecta contraseñas, switches de clientes, problemas de configuración en xDoctor y soluciona problemas conocidos de claves SSH debido a reemplazos de switches. Proporciona un resumen detallado de sus hallazgos y si solucionó algún problema de clave SSH. Esta solución funciona en los switches de 2.ª y 3.ª generación para la detección y resolución de claves SSH.
Para obtener más información sobre la configuración de las automatizaciones, siga los siguientes pasos: ECS: ObjectScale: Cómo ejecutar scripts de automatización de KB (piloto automático)
Para encontrar el nodo maestro del rack:
Comando:
ssh master.rack
Para encontrar la IP de NAN, puede utilizar la IP identificada en la alerta o desde getrackinfo:
Comando:
admin@ecsnode1:~> getrackinfo
