command as follows:
# vxprint -g PRODdg

Identify that the specified plex is in the snapdone state. In this example, it is
data_vol-02.
The snapshot mirror is now ready to be used.
Upgrading Existing Volumes to Use Veritas Volume Manager 5.0
The procedure in this section describes how to upgrade a volume created using a version
older than VxVM 5.0 so that it can take advantage of database FlashSnap.
NOTE The plexes of the DCO volume require persistent storage space on disk to be available.
To make room for the DCO plexes, you may need to add extra disks to the disk group, or
reconfigure existing volumes to free up space in the disk group. Another way to add disk
space is to use the disk group move feature to bring in spare disks from a different disk
group.
NOTE Existing snapshot volumes created by the vxassist command are not supported. A
combination of snapshot volumes created by vxassist and vxsnap are not supported.
To upgrade an existing volume created with an earlier version of VxVM:
1. Upgrade the disk group that contains the volume, to a version 120 or higher, before
performing the remainder of the procedure described in this section. Use the
following command to check the version of a disk group:
# vxdg list diskgroup
To upgrade a disk group to the latest version, use the following command:
