Veritas Storage Foundation Intelligent Storage Provisioning 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

If the specified volume is currently enabled, the data in enabled plexes and their
component enabled plexes is moved without interrupting the availability of the
volume and without changing its redundancy. Subdisks that are within detached
plexes, disabled plexes, detached logs, or RAID-5 subdisks are moved without any
attempt to recover the data.
If the specified volume is not currently enabled, stale or offline plexes are moved
without recovery. The evacuation fails if a non-enabled volume contains other
subdisks that need to be moved.
Removing a volume
When a volume is no longer required, use the following command to delete it and
make its storage available for re-use:
# vxassist [-g diskgroup] remove volume volume
For example, the following command removes the volume, vol1:
# vxassist -g mydg remove volume vol1
Performing online relayout on a volume
ISP does not support online relayout of an application volume in the same way
as when the vxassist relayout command is used on a traditional volume. ISP
can perform relayout internally if this is necessary to preserve the intent of a
volume, or to support operations such as changing the number of mirrors, columns
or logs that are associated with a volume. However, you should note that such
operations may destroy the intent of a volume by changing its desired data
redundancy or performance capabilities.
The nearest equivalent in ISP to the online relayout operation is capability
transformation. This changes the capabilities of a volume in a controlled fashion,
and preserves the size of the volume but not its intent.
See Transforming the capabilities of a volume online on page 86.
You can also add or remove mirrors, columns or logs to or from a volume, stop
and reverse transformation and relayout operations, and verify that the intent
of a volume has been preserved.
