Physical volume not getting listed in `pvs` command even after creating it with `pvcreate` command and seeing in lvm metadata file in `/etc/lvm/backup/<vgname>`

Issue

• Physical volume is not getting listed in the output of pvs command even after creating it with pvcreate command. It is also seen in the lvm metadata file in /etc/lvm/backup/backup_vg

backup_vg {
    id = "AFspCj-O7ZI-5MLF-nJTi-1VKu-yWlr-DJpntC"
    seqno = 1
    status = ["RESIZEABLE", "READ", "WRITE"]
    flags = []
    extent_size = 8192      # 4 Megabytes
    max_lv = 0
    max_pv = 0
    metadata_copies = 0

    physical_volumes {

        pv0 {
            id = "TfRcQU-yiYh-ydTQ-YoA6-qvwA-w0cg-szviJ1"
            device = "/dev/mapper/mpathep1" # Hint only

            status = ["ALLOCATABLE"]
            flags = []
            dev_size = 6291472384   # 2.9297 Terabytes
            pe_start = 2048
            pe_count = 768001   # 2.92969 Terabytes
        }
    }

Output of lvm commands is

# cat sos_commands/devicemapper/pvs_-a_-v |grep backup_vg
# cat sos_commands/devicemapper/vgs_-v |grep backup_vg

We could see the mpathep1 partition in the output of ls -lR /dev/ command

lrwxrwxrwx 1 root root   11 Jun 23 11:26 dm-name-mpathe -> ../../dm-14
lrwxrwxrwx 1 root root   11 Jun 23 12:51 dm-name-mpathep1 -> ../../dm-15

There is no UUID seen for the dmsetup device

Also, partitions are seen missing for the underlying devices of mpathe.
