ON 3.10.0-957.27.2.el7, I see:
# vxddladm list devices DEVICE TARGET-ID STATE DDL-STATUS (ASL) =============================================================== nvme0n1 - Online CLAIMED (libvxnvme.so) sdc - Online CLAIMED (Disk) sdb - Online CLAIMED (Disk) sda - Online CLAIMED (Disk)
On 3.10.0-1062.1.1.el7, I see:
# vxddladm list devices DEVICE TARGET-ID STATE DDL-STATUS (ASL) =============================================================== sda - Online CLAIMED (Disk) sdb - Online CLAIMED (Disk) nvme0n1 - Online ERROR (libvxnvme.so)
That's interesting because both systems are using the same ASL:
# rpm -qf /etc/vx/lib/discovery.d/libvxnvme.so VRTSaslapm-7.4.1.1200-RHEL7.x86_64

I upgraded the asl rpm and at one point, the NVMe drive showed up after the upgrade.. but it was gone upon the next reboot:

This appears to be caused by an issue with NVMe SCSI VPD information on el7.7 kernels:
