To create a multi-mirror snaphot
1
Add the second mirror and DCO log. When allocating storage for the second
mirror and DCO logs, make sure the snap volumes are splittable. If snap
volumes are not splittable, dbed_vmchecksnap fails with appropriate errors.
# vxsnap -g dg_a addmir dg_a_vol1 alloc=dg_a03
2
Tag the newly added mirror with the same tag as that of the first mirror.
Assume that the volume has fastresync = on, has dcolog = on, and already
has one SNAPDONE mirror and is tagged with .
# vxedit -g dg_a set putil2=dbed_flashsnap dg_a_vol1-03
