After you upgrade from previous versions to 6.2, you have to upgrade the disk group version manually.

To upgrade disk group version, you have to first upgrade the cluster protocol version using the vxdctl upgrade command.

# vxdctl list
Volboot file
version: 3/1
seqno:   0.1
cluster protocol version: 120
hostid:  sys1
hostguid:  {fca678ac-e0ef-11e2-b22c-5e26fd3b6f13}
# 
# vxdctl upgrade
#

# vxdctl list

Volboot file
version: 3/1
seqno:   0.2
cluster protocol version: 140
hostid:  sys1
hostguid:  {fca678ac-e0ef-11e2-b22c-5e26fd3b6f13}

Verify if the cluster protocol version shows 140 and disk group version is upgraded to 200.

# vxdctl list |grep version

version:   140
#
# vxdg upgrade dg_name
#
# vxdg list dg_name |grep version

version:   200
