This issue occurs when udevadmn and dell's omreport don't show the exact same serial number for a disk. With these particular 12T disks, udevadmn reported a longer version of serial number and omreport reported a shorter version.

[root@linux integralstor]# udevadm info -q property -n sda | grep -ie ID_SCSI_SERIAL | cut -d "=" -f2

serial numbers from both the commands are compared in disk.py's get_disk_status(), comparison fails since they don't match.
