Error Message
# vxsnap -g datadg make snap=snap_datavol/source=datavolVxVM vxassist ERROR V-5-1-16668 Volume snap_datavol does not have the same devsubtype as that of datavol
Cause
In SF6.0.3, when a volume is created, the default devsubtyp for the volume is "dsvm". In SF5.1SP1, when a volume is created, the default devsubtyp for the volume is "none." This may cause an error when attempting to resync, or refresh, a snap volume if the source volume is created in SF5.1SP1 and system was then upgraded to SF6.0.3.
The VxVM volume attribute "devsubtype" is used only on the AIX platform.
Resolution

# vxprint -g datadg -m datavol | grep devsubtype
devsubtype=none
# vxprint -g datadg -m snap_datavol | grep devsubtype
devsubtype=dsvm
Changing the devsubtype to dsvm for the original volume and the snapshot can be created:
# vxvol -g datadg set devsubtype=dsvm datavol
# vxprint -g datadg -m datavol | grep devsubtype
devsubtype=dsvm
The snapshot now creates.
# vxsnap -g datadg make snap=snap_datavol/source=datavol
