Symptoms

Cuando el software de escaneo Tenable escanea el puerto 9083, el proceso de administración remota de PowerPath con mTLS habilitado falla y, finalmente, alcanza el máximo de conexiones de socket y se registra el restablecimiento de la conexión mediante un mensaje de par.

 

En la GUI de PPMA, el estado desconectado no se observa hasta el siguiente ciclo de sondeo. Cuando se ejecuta el ciclo de sondeo, el servidor finalmente se muestra como desconectado en la GUI (ROJO).

Cause

Este problema se debe a que la administración remota de PowerPath para Windows 7.2.X con mTLS habilitado no maneja correctamente las conexiones de Winsock desde un servidor que no es PPMA.

 

Resolution

La corrección estará en la versión futura de PowerPath para Windows, pero no hay una ETA en este momento.

 

La solución alternativa es reiniciar el servicio "componente de EMC PowerPath Remote Management" desde los servicios de Windows.
