To create a snapshot mirror of a volume
1
Create a volume:
vxassist -g diskgroup make volume_name size disk_name
For example:
# vxassist -g PRODdg make snapvset_1 8g data01
2
Create a DCO and enable FastResync on the volume:
vxsnap -g diskgroup prepare volume_name [alloc=storage_attribute]
For example:
# vxsnap -g PRODdg prepare snapvset alloc="snap01"
3
Verify that a DCO and DCO log are attached to the volume:
vxprint -g diskgroup -F%fastresync volume_name
vxprint -g diskgroup -F%hasdcolog volume_name
This command returns on if a DCO and DCO log are attached to the specified
volume.
For example:
# vxprint -g PRODdg -F%fastresync snapdata
on
# vxprint -g PRODdg -F%hasdcolog snapdata
on
4
Create a mirror of the volume:
vxsnap -g diskgroup addmir volume_name [alloc=storage_attribute]
For example:
# vxsnap -g PRODdg addmir snapdata alloc="data02"
