To create a snapshot mirror of a volume set

Create a volume:

vxassist -g diskgroup make volume_name size disk_name

For example:

# vxassist -g PRODdg make snapvset_1 8g snap01

# vxassist -g PRODdg make snapvset_2 4g snap01

Create a volume set for use by VxFS:

vxvset -g diskgroup -t vxfs make vset_name volume_name

For example:

# vxvset -g PRODdg -t vxfs make snapvset snapvset_1

Add the volume to the volume set:

vxvset -g diskgroup addvol vset_name volume_name

For example:

# vxvset -g PRODdg addvol snapvset snapvset_2

Create a DCO and enable FastResync on the volume set:

vxsnap -g diskgroup prepare vset_name [alloc=storage_attribute]

For example:

# vxsnap -g PRODdg prepare snapvset alloc="snap01"
