When we want to find the HCTL values for a device, we grep the target_WWN in /sys/class/fc_transport/target8:*/port_name path. If we find it then we use the HCTL values from the path like, target8:0:1 where 8 -> host, 0 -> channel, 1 -> target and LUN number is received from the storage array. If we fail to find the device in fc_transport path, we search in fc_remote_ports path which contains info about all connected devices whether it be storage array port or switch port. We found an issue with the exception handling when we don't find a valid path in fc_transport location eventually raising an exception and skipping the search in fc_remote_ports path. This patch adds exception handling for both fc_transport and fc_remote_ports paths so any errors in individual path doesn't affect the other.
