diskdump using swap device defined as a logical volume



I was trying to enable diskdump using a swap space, which is itself a
logical volume.
When I tried to enable it, the command failed and /var/log/messages has
an entry stating that is not supported:

Feb 27 14:35:11 build43 diskdump: diskdumpctl:
/dev/mapper/VolGroup00-LogVol00 is not supported!
Feb 27 14:35:11 build43 diskdump: activating failed

(as a side note, the swap device defined as /dev/VolGroup00/LogVol00 was
NOT initially formatted, as suggested in a knowledge base doc)

So my questions are:

Does anybody know if there are any plans to allow LVs to be used as dump
devices, or work-arounds other than using netdump?
If so, what is the expected time frame?

Any help is greatly appreciated.

Thanks.
