To convert volume groups to disk groups
◆
Run the vxautoconvert command:
# /usr/sbin/vxautoconvert [-f] [vgname ...]
The volume groups may be specified by their names or full pathnames. If no
volume groups are specified, conversion of all volume groups on the system
is attempted.
If the value of the system tunable, nproc, is too low, the analysis will report
that the conversion of the volume groups cannot be performed in parallel.
In that case, you can use the -f option to specify that the volume groups are
to be converted one at a time.
See the vxautoconvert(1M) manual page.
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 [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.
