Soltuion:
To get rid of this, solution is to re-create device mapping, restart vxconfigd, initialize the device, add the disk back to the diskgroup.
# vxdisk rm NONAMEs2 (Remove the device entry in Volume Manager)
# cd /dev/vx/rdmp (Delete all files pertaining to NONAME*)
# cd /dev/vx/dmp (Delete all files pertaining to NONAME*)
# mv /etc/vx/disk.info /etc/vx/disk.info.old
# mv /etc/vx/array.info /etc/vx/array.info.old
# devfsadm -Cv
# vxddladm stop eventsource
# vxconfigd -k (This will recreate the device mapping and the disk.info file)



Remove all the disk with name NONAME
# vxdisk rm NONAMEs2

# pwd
/dev/vx/rdmp
# ls -lrt|grep -i NONAME

The output is much longer, i had shrinked the output.

After troubleshooting from vxvm end, Disk are visible now, I will be extending the FS today.
