Hello,
On RHEL7, can anyone explain why WWN are trucated with the "lsblk"
command compared to "lsscsi"?
[root@xxx ~]# lsblk -o +wwn --raw | awk '$6 == "disk"'

Reply to myself: using "serial" instead of "wwn" in lsblk does the
trick. I'm still unable to display a serial/wwn with a compiled lsblk
but in the worst case I can use jc:
lsblk -o +serial | jc --lsblk | jq .
Also, if I try to compile a newer version of lsblk to have the --json
option, the wwn is blank :
[root@xxx ~]# /opt/util-linux-2.38.1/bin/lsblk --json -o +wwn
