You can specify plenty of columns in whatever order you like:
Available columns:
NAME device name
KNAME internal kernel device name
MAJ:MIN major:minor device number
FSTYPE filesystem type
MOUNTPOINT where the device is mounted
LABEL filesystem LABEL
UUID filesystem UUID
RO read-only device
RM removable device
MODEL device identifier
SIZE size of the device
STATE state of the device
OWNER user name
GROUP group name
MODE device node permissions
ALIGNMENT alignment offset
MIN-IO minimum I/O size
OPT-IO optimal I/O size
PHY-SEC physical sector size
LOG-SEC logical sector size
ROTA rotational device
SCHED I/O scheduler name
RQ-SIZE request queue size
TYPE device type
DISC-ALN discard alignment offset
DISC-GRAN discard granularity
DISC-MAX discard max bytes
DISC-ZERO discard zeroes data
With udev, You can use
ls -l /dev/disk/by-label
to show the symlinks by label to at least some partition device nodes.
Not sure what the logic of inclusion is, possibly the existence of a label.
There is a blkid command which may be what you are looking for. Results are similar to the following:
$ sudo blkid /dev/mapper/vg_rootdisk-lv_var
/dev/mapper/vg_rootdisk-lv_var: LABEL="LV_VAR" UUID="08520908-03cd-4e42-a4e4-0f5a771be16c" TYPE="ext4"
One other option is to use the udevadm command, which likely will give you far more than you need:
$ sudo udevadm info --query=all --name=/dev/mapper/vg_rootdisk-lv_var
