Visualizando WWPN s no Linux

Para visualizar as WWPNs no Linux, fica fácil com o seguinte script:

#!/bin/sh

FC_PATH="/sys/class/fc_host"
 
for fc_adapter in `ls ${FC_PATH}`
do  
    echo "${FC_PATH}/${fc_adapter}:"
    NAME=$(awk '{print $1}' ${FC_PATH}/${fc_adapter}/symbolic_name )
    echo "  $NAME `cat ${FC_PATH}/${fc_adapter}/port_name`"
done

A Saída é consolidada da seguinte forma:


$ print_wwpns
/sys/class/fc_host/host5: QLE2562 0x21000024ff45afc2 

/sys/class/fc_host/host6: QLE2562 0x21000024ff45afc3

Procurando um pouquinho na net encontrei o estiloso comando que também pode ser usado para recuperar informações do SYSFS.
