we have rhel 7.6 server with sdb and sdc and sdd disks

the machine is physical machines with disk of 1.7T each of them

we notice the sdd disk displayed from lsblk as

 lsblk | grep data
sda                8:0    0   1.7T  0 disk /data/sdc
sdc                8:32   0   1.8T  0 disk /data/sdb
sdd                8:48   0   1.8T  0 disk /data/sdd
sde                8:64   0   1.7T  0 disk /data/sde

but when we do the following in order to find the UUID number as

blkid /dev/sdd

then no output

actually we need to get example as

 blkid /dev/sdd
/dev/sdd: UUID="941546ac-2168-4130-b51f-f5a255a4e43c" TYPE="ext4"

what could be the reasons for that and suggested solution?

Note - disk with UUID defined correctly in /etc/fstab

If lsblk command is working fine in your system then you can use the below command to get UUID of the disk

[root@ansible-tower ~]# lsblk -f
