# vxsnap [-g diskgroup] unprepare volume
For the example output, the command would take this form:
# vxsnap -g mydg unprepare vol1
4. Start the volume using the vxvol command:
# vxvol [-g diskgroup] start volume
For the example output, the command would take this form:
# vxvol -g mydg start vol1
5. Prepare the volume again using the following command:
# vxsnap [-g diskgroup] prepare volume [ndcomirs=number] \
[regionsize=size] [drl=yes|no|sequential] \
[storage_attribute ...]
For the example output, the command might take this form:
# vxsnap -g mydg prepare vol1 ndcomirs=2 drl=yes
This adds a DCO volume with 2 plexes, and also enables DRL and FastResync (if
licensed).
See the VERITAS Volume Manager Administrator’s Guide and the vxsnap(1M) manual
page for full details of how to use the vxsnapprepare command.
