To find the Fibre
Channel addresses of the HBAs on the machine, run the following:
|
# systool -c fc_host -v
(output trimmed for clarity)
Class Device path = "/sys/class/fc_host/host8" (kernel assigned host name/number)
node_name =
"0x20000024ff2254bf" (hba
wwnn )
port_name = "0x21000024ff2254bf" (hba wwpn )
port_id =
"0x030b00"
(fabric port id assigned by the san to this HBA)
Class Device path = "/sys/class/fc_host/host9"
node_name =
"0x20000024ff2254be"
port_name = "0x21000024ff2254be"
port_id =
"0x010c00"
or alternatively
# ls -1c /sys/class/fc_host/host*/*_name
2> /dev/null | xargs -I {} grep -H -v "ZzZz" {} | sort
/sys/class/fc_host/host8/fabric_name:0x100000053367f20d
