Este documento describe un procedimiento cuando experimenta una utilización del rendimiento del disco que alcanza el 100% y la necesidad de verificar si se trata de un problema de aplicación o de un problema de hardware, se le requiere ejecutar varios comandos para analizar la situación.
No hay requisitos específicos para este documento.
La información que contiene este documento se basa en las siguientes versiones de software y hardware.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
El sistema funciona con lentitud y no es estable. El rendimiento del disco llega al 100%.
La manera rápida y sencilla es acceder a la interfaz web de administración y examinar el estado del hardware de almacenamiento.
Cuando no hay acceso a Cisco Integrated Management Controller (CIMC) administración remota para Unified Computing System (UCS) Series o Integrated Lights-Out (ILO) en servidores HP, puede obtener la información sobre RAID y discos mediante este método:
Para servidores Cisco Unified Computing System (UCS):
Las distribuciones de Debian utilizan un paquete denominado "megacli".
Más información sobre esta herramienta - http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS
Ejemplos de cómo utilizar el comando - http://www.mostlychris.com/blog/2009/07/29/check-raid-status-with-megacli/
El paquete para debian puede ser descargado e instalado.
Nota: Se prueba con megacli_8.07.14-1_amd64.deb
Para verificar qué controladores de hardware se utilizan, ejecute el comando: sudo lspci -vv | grep -i RAID
p. ej.
Controlador de bus RAID 82:00.0: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05)
Controlador del núcleo en uso: megaraid_sas
puede encontrar más información sobre este comando en:
Ejecutándolo como root, ejecute el comando: sudo /usr/bin/megacli
Paso 1. Busque los detalles del controlador RAID, ejecute el comando: lspci -vv | grep -i RAID.
El controlador RAID es un dispositivo.

Comprobación de la batería
Puede guardar el registro para un análisis posterior.
Para HP hay un paquete especial para Debian que necesita ser instalado para obtener acceso al controlador RAID y a los discos físicos. El paquete se denomina hpacucli_9.40.1-1._amd64.deb
Paso 1. Instalación:
Una vez finalizada la instalación, puede trabajar con la manipulación RAID mediante la siguiente herramienta CLI: hpacucli
La herramienta permite obtener la información adecuada del controlador RAID, así como cambiar la configuración con los componentes RAID.
Paso 2. Mostrar detalles de configuración del controlador, ejecutar comando: hpacucli ctrl all show config detail.

A veces, una batería defectuosa en uno de los servidores puede ser la razón. Debería reemplazarlo.
Esto resuelve el problema y reduce el uso del alto rendimiento del disco.
