Veritas Disk group

[Vasikaran Venkatesan]

Is there any such thing like making the VRTS Diskgroup as cluster aware ?. (like it is done for LVM VG).

No Veritas Disk group need not be made cluster aware, only the activation mode is importatnt like exclusive mode or shared mode also you have to specify the DG that the involved in the package. Have a look at the package script and you'll have all the idea.
Here is a cut and paste portion from the package configuration file.
# CVM DISK GROUP ACTIVATION:
# Specify the method of activation for CVM disk groups.
# Leave the default
# (CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=exclusivewrite")
# if you want disk groups activated in the exclusive write mode.
#
# Uncomment the first line
# (CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=readonly")
# if you want disk groups activated in the readonly mode.
#
# Uncomment the second line
# (CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=sharedread")
# if you want disk groups activated in the shared read mode.
#
# CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=readonly"
# CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=sharedread"
CVM_ACTIVATION_CMD="vxdg -g \$DiskGroup set activation=exclusivewrite"

# CVM DISK GROUPS
# Specify which cvm disk groups are used by this package. Uncomment
# CVM_DG[0]="" and fill in the name of your first disk group. You must
# begin with CVM_DG[0], and increment the list in sequence.
#
# For example, if this package uses your disk groups dg01 and dg02, enter:
# CVM_DG[0]=dg01
# CVM_DG[1]=dg02
#
# The cvm disk group activation method is defined above. The filesystems
# associated with these volume groups are specified below in the CVM_*
# variables.
