Please consider to define a constant instead of using a magic number
everywhere. Like:
#define _DISK_WWN_MAX_LEN 35
/* ^ WWN here is extracted from /dev/disk/by-id/wwn-<WWN> which is
* created by udev 60-persistent-storage.rules using ID_WWN_WITH_EXTENSION.
* The udev ID_WWN_WITH_EXTENSION is the combination of char wwn[17] and
* char wwn_vendor_extension[17] from struct scsi_id_device.

Please use constant instead of magic number:
printf("%-*s ", _DISK_WWN_MAX_LEN - 1, wwn_str);
