To analyze volume groups for conversion
◆
Run the vxautoanalysis command:
# /usr/sbin/vxautoanalysis [-f] [vgname ...]
The volume groups may be specified by their names or full pathnames. If no
volume groups are specified, analysis 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 analysis 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 analyzed one at a time.
See the vxautoanalysis(1M) manual page.
Converting volume groups to disk groups
The vxautoconvert utility converts one or more LVM volume groups to VxVM
disk groups. Any LVM extent-based striped volumes are converted to stripe-mirror
(non-layered) VxVM volumes.
Note: The VxVM configuration daemon (vxconfigd) must be running in order for
the conversion to succeed. Conversion of the root volume group is not permitted.
An error results if this is attempted.
