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 this procedure. 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:
# vxdg upgrade diskgroup
2
If the volume to be upgraded has a DRL plex or subdisk from an earlier version
of VxVM, use the following command to remove this:
# vxassist [-g diskgroup] remove log volume [nlog=n]
Use the optional attribute nlog=n to specify the number, n, of logs to be
removed. By default, the vxassist command removes one log.
3
For a volume that has one or more associated snapshot volumes, use the
following command to reattach and resynchronize each snapshot:
# vxsnap [-g diskgroup] snapback snapvol
If persistent FastResync was enabled on the volume before the snapshot was
taken, the data in the snapshot plexes is quickly resynchronized from the
original volume. If persistent FastResync was not enabled, a full
resynchronization is performed.
4
Use the following command to turn off persistent FastResync for the volume:
# vxvol [-g diskgroup] set fastresync=off volume
5
Use the following command to dissociate a DCO object from an earlier version
of VxVM, DCO volume and snap objects from the volume:
# vxassist [-g diskgroup] remove log volume logtype=dco
