Fibre channel – apuntes

Para ver el WWN de una HBA:

systool -av -c fc_host        # systool pertenece al paquete sysfsutils. Sacar la línea port_name

Misc:

multipath -ll
sg3-utils package:
	sg_map
	sg_scan -i

cat /proc/scsi/scsi

You can get the Fiber Channel addresses of the HBAs by typing the following commands:
# systool -c fc_host -v

Type the following command to determine the fibre channel target WWN:
# systool -c fc_transport -v

You will get node name (FC WWN) and port name of the storage processor port. Type the following command, to determine the mapping between SCSI HBTL addresses and the disks:
# sg_map -x
