UNIX, HP-UX, tarjetas de fibra

Para localizar los devices de las HBA hacemos:

ioscan -fnCfc

o también: ioscan -kfnCfc

(la opción k consulta en el Kernel. Ioscan contestará rápido porque no analiza el hardware, pero si ha habido cambios desde el anterior ioscan completo, no los verás).

Luego podemos utilizar la utilidad “Fibre Channel Mass Storage Utility”.

Esto nos permite entre otras cosas saber el WWW de una HBA y su estado.

El WWN que ve un dispositivo remoto es el N_PORT PORT WORLD WIDE NAME.

A nivel de los switches de fibra los fabricantes nos suelen proporcionar el software para recopilar toda la información de zonning y WWW. Incluso nos mostrarán de forma gráfica todas las conexiones de fibra (en caso de Brocade en un gráfico Visio).
