Joining disk groups
Joining two CDS disk groups or joining two non-CDS disk groups is permitted,
but you cannot join a CDS disk group to a non-CDS disk group. If two non-CDS
disk groups have different alignment values, the alignment of the resulting
joined disk group is set to 1, and an informational message is displayed.

Changing the default CDS setting for disk group creation
To change the default CDS setting for disk group creation
◆ Edit the /etc/default/vxdg file, and change the setting for the cds
attribute.
Creating non-CDS disk groups
A disk group with a version lower than 110 is given an alignment value equal to
1 when it is imported. This is because the
dg_align value is not stored in the
configuration database for such disk groups.
To create a non-CDS disk group with a version lower than 110
◆ Type the following vxdg command:
# vxdg -T version init diskgroup disk_name=disk_access_name
