Adding a Version 0 DCO and DCO Volume
310 VERITAS Volume Manager Administrator’s Guide
To dissociate, but not remove, the DCO object, DCO volume and any snap objects from
the volume, myvol, in the disk group, mydg, use the following command:
# vxdco -g mydg dis myvol_dco
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.
