Converting a volume group
To do the actual conversion of LVM volume groups to VxVM disk groups, choose
option 2 of the vxvmconvert utility.
vxvmconvert will prompt for a name for the VxVM disk group that will be created
to replace the LVM volume group you are converting. This is the only object
naming that is done through vxvmconvert. Additional details are available on
modifying VxVM volume names.
See “Tailoring your VxVM configuration” on page 413.
As described earlier, the volume groups selected for conversion are analyzed to
ensure that conversion is possible.
See “Analyzing an LVM volume group to see if conversion is possible” on page 406.
After a successful analysis phase, vxvmconvert prompts you to commit to the
change or abort the conversion. When you select to commit to conversion, the
new VxVM metadata is written. Before the conversion is committed, the
vxvmconvert operation displays the estimated required time as:
VxVM INFO V-5-2-4906
The expected time for convert is: 0 hrs 0 mins 7 secs.
Note: The time required for conversion is an estimate and is not a calculated time.
The actual conversion time may differ depending on factors like number of CPUs,
Memory, I/O throughput, etc.
More information is available on the details of the conversion process.
See “Examples” on page 417.
Taking actions if conversion fails
There are several reasons why conversion can fail.
See “Volume group conversion limitations” on page 403.
Messages from vxvmconvert explain the type of failure, and any actions you can
take before retrying the conversion.
Complete details of specific error messages are available.
See “List of conversion error messages” on page 507.
