47Converting LVM to VxVM
Non-interactive conversion of volume groups
Converting disk groups back to volume groups
The vxautorollback utility converts one or more VxVM disk groups back to the
LVM volume groups from which they had previously been converted.
Note: The VxVM configuration daemon (vxconfigd) must be running in order
for the analysis to succeed.
Reverse conversion is performed on each disk group in turn. Parallel conversion
is not supported.
If the configuration or layout of the volumes in the converted disk group has
been changed since conversion from LVM to VxVM, reverse conversion is not
possible.
The records of the converted volume groups are stored in the directory
/etc/vx/reconfig.d/vgrecords. Reverse conversion is not possible if
these records are removed or modified.
To convert disk groups back to volume groups
◆ Run the vxautorollback command:
# /usr/sbin/vxautorollback [-f] [ dgname ...]
The disk groups may be specified by their names or full pathnames. If no
disk groups are specified, conversion is attempted for all disk groups on the
system that have volume group records stored in the directory
/etc/vx/reconfig.d/vgrecords.
See the
vxautorollback(1M) manual page.
