Currently with '--wwn' flag 128-bit wwns are getting truncated with their last 3 hex-digit missing. Below is a comparison of wwn reported by lspsci compared to wwn listed at /dev/disk/by-id directory.
% lsscsi -w 0:0:5:0 [0:0:5:0] disk 0x60050764008181941000000000000 /dev/sdad % ls -l /dev/disk/by-id/wwn-* lrwxrwxrwx. 1 root root 10 Oct 19 01:08 /dev/disk/by-id/wwn-0x600507640081819410000000000001b1 -> ../../sdad To fix this the patch increases the size of member wwn of struct disk_wwn_node_entry to 35 chars to accommodate the extra '0x' prefix and null terminator. Also the size of the buffer wwn_str thats used to output wwn to the std-out is also increased to match the corresponding member of disk_wwn_node_entry.
