359Administering volume snapshots

Adding a version 0 DCO and DCO volume

This form of the command dissociates the DCO object from the volume but does

not destroy it or the DCO volume. If the

-o rm option is specified, the DCO object,

DCO volume and its plexes, and any snap objects are also removed.

Note: Dissociating a DCO and DCO volume disables Persistent FastResync on the

volume. A full resynchronization of any remaining snapshots is required when

they are snapped back.

For more information, see the

vxassist(1M) and vxdco(1M) manual pages.

Reattaching a version 0 DCO and DCO volume

Note: The operations in this section relate to version 0 DCO volumes. They are

not supported for version 20 DCO volume layout that was introduced in VxVM

4.0.

If the DCO object and DCO volume are not removed by specifying the

-o rm

option to

vxdco, they can be reattached to the parent volume using the following

command:

# vxdco [-g diskgroup] att volume dco_obj

For example, to reattach the DCO object, myvol_dco, to the volume, myvol, use

the following command:

# vxdco -g mydg att myvol myvol_dco

For more information, see the vxdco(1M) manual page.
