43Converting LVM to VxVM
Examples
volume such as recovery and data access will be governed by the usage type
fsgen.
■ The plex dg08lv1-01 is associated with volume dg08lv1, and maps the
entire address range of the volume. Associated with the plex is one subdisk,
dg0801-01 which maps the plex address range from 0 to the entire length of
the plex, i.e. 102400 blocks. As implied by the root of its name, the subdisk
dg0801-01 uses an extent from the VxVM disk dg0801.

Use this operation to rollback from a conversion of an LVM Volume Group. This
operation will tear down the VxVM disk group and recreate the LVM volume
group in its original form. User data is untouched by rollback.
Caution: If the VxVM configuration has changed since the conversion you
should NOT use this operation. See the section “Restoring the LVM volume
group configuration” for more information.
More than one Volume Group or pattern may be entered at the
prompt. Here are some LVM Volume Group selection examples:
all: Rollback all converted LVM Volume Groups
listvg: list all LVM Volume Groups eligible for rollback
list: list all disk devices
vg_name:a single LVM Volume Group, named vg_name
<pattern>:for example vg08 vg09 vg05
Select Volume Group(s) to rollback :
